I've been doing a lot of testing with different sim cards the last few days, and thought I'd share my results. I have identified with 100% certainty the reason why some people on miui can't get wifi calling working, while others can. It is 100% caused by the sim card. If you have the older style sim card, with the black numbering on the front, it will work every time. Newer style it doesn't, or maybe once per 50 reboots. (That one has gold lettering on the front.)
Another thing I've discovered, (which ironically I wasn't testing for ), is this also seems to be the cause of the "apn issue" that people have on cm7. Same deal, older style sim cards don't seem to have it at all. Newer ones do. I have access to 3 different sim cards from tmobile, all activiated on different numbers. I have two of the newer style ones, and one older. Each test was done with 30 reboots each. (I was going cross-eyed by the end of it.)
1st card, new style, one I got with the phone.
- Miui - No wifi calling at all
- cm7 - Apn issue 4 out of 30 reboots
2nd card, also new style, from a different phone.
- Miui - Again, no wifi calling working on any boot
- cm7 - Apn issue 6 out of 30 reboots
3rd card, old style sim card (and although they say new ones increase the 4g speed, after multiple tests I didn't see one difference between any of them speed wise)
- Miui - Wifi calling working perfectly on every boot
- cm7 - not one apn issue out of 30 boots.
So, while this is a small sample size, (I don't have more sim cards, and I really couldn't do more than 90 reboots without loosing my mind), it seems to show the cause of the problem.
There really isn't much I can see them being able to fix this. I'm guessing the miui devs and cm7 devs are using testers that have the old style sim card, or have the old style themselves (depending on if they have the phone or not.) Now since you can't really troubleshoot an issue you can't re-create, this might be something we all have to live with.
I just figured I'd post this so people who had these issues know now they're not insane, and they're not doing anything wrong, it's a compatibility issue.
If anyone else does find something different than what my tests show, please either respond or send me a pm. I'd be very interested to see others results as well. (Like I said, correlation is not causation, so this could very well be a fluke test with such a small sample size.)
Good job on the test. Unfortunately I have a sim card with black writing, and I still have the APN issues with CM7, as well as the occasional wifi calling issue.
Damn. Well it is sim card related, but perhaps there are a few more types that I wasn't able to test with. Did you get your sim-card with the phone? Or did you have an older phone and used the same simcard in the newer one? (The old one I'm using is at least 4 years old, if that helps.)
how can i help
Thanks for the info. I bet that drove you up a wall. I have 1 maybe 2 of the old "3g" Sims. And 2 newer ones from TMobile Replacing the "3g" ones. And I have 4 brand new ones that came with both of my devices. I kept them when I returned the phone. Let me see what I can do to help. I run cm7 and modified versions of the stock rom. I have big time issues and want to help resolve this.
I agree with the comments about developers....but remember this not there day jobs and they do depend on us to submit info...but then with all of the talk about apn's you would think at least one would have fought on. I have a copy of xboarders Apn fix....never really looked at it. I just keep using apnsbu from the market. I will report back with findings. Thinks for. The post and something to do...
Oh that statement wasn't in any way meant to be a shot at any of the devs, I'm just stating that you can't blame them not being able to look at a problem they are unable to re-create. Infact, it was just the opposite. It was more like saying it's not their fault in the least.
And please let me know your results. (Yes, it was driving me nuts. I've been going through logs, the init.rc, all the added init scripts, everywhere trying to figure out why it wasn't working. This was a last ditch effort, figuring it couldn't possibly be this but there was nothing else to try. Go figure )
This is turning out to be very tedious. My old sim from my tmo shadow/Juno days is a bit unreadable. The number has been tuned and is in readable. But no worries the bb still works and disabled to read the serial number....now on hold with TMobile. I am starting to think I really called at&t. Any how what I would like to knowis how can we identify what card is what. I see some noticeable differences like the old one has a big ger gold contact area, the numbers where in black, and the design on the old one on the contact side is gray. There is. Nothing legible on it. But I do know it is one of the old ones. Is came with a 3g phone from like 3 years ago. I am supplying this info to possibly help identify what Sims work. I will post pics later if needed.....still waiting. Off topic but all three hold songs suck. If they want to keep people happy then they should get some new "caller tunes" will report back more later....25 minutes on hold now.......

I believe my sim card is around 3 years old, but I'm trying to think whether I might have gotten a new one during one of my phone upgrades. Not really sure...
Ok I can not further test this today. Turns out that they have to release the old similar card.?.?. What ever that means. Did some questioning. This is what I got. My old card is a 2g. The new cards are 3g. 3g card is needed for 4g. How to tell a 3g from 2g is a marking on the contact side of the card. 3G cards say "TM9073"
So if people could help with trend analys that would help a lot. Info need is...
1) do you have apn issues.
2) what, if any, markings do you have on the contact side of your sim.
3) what rom and version are you using.
4) kernel info.
5) baseband.
This could be helpfully to us and any developer that is willing to help figure this out.
Edit: I have not tried the miui roms. I will help as much as I can with miui, but I think this is the same issue with different Results. So I am adding in the rom question.
Edit 2) wifi calling will come up invalid sim when apn is lost on cm7
1) do you have apn issues.
Yes
2) what, if any, markings do you have on the contact side of your sim.
No markings on the contact side of the sim
3) what rom and version are you using.
CM7 Nightly 114

BY THE WAY NEW R34 128k sims are now available.
im currently running this sim and i have no issues whatsoever!
Do you know of any way on how to id this sim? From others?
If you have an old T-Mobile sim you should be able to call them and tell them you wish to change your number and service to the old sim card. You give them the number on the old sim (if you can read it) and tell them you want to do a sim swap. I have done this before on a prepaid account. I don't see how a sim could increase your data connection speed. The new sims just have larger phone books and can accept longer names, etc.
I called yesterday. They released the sim. What ever that does. So some time today I need to call back and set it up. I have many sims on hand to try but this is the oldest one. I am not worried about how many numbers I can store on. I just want to help try and find a solution to the apn issues using custom roms. Any information posted here in regards to apn or sim cards is usefull. I see people reading this so please chime in. Even the smallest bit of info could help.

Ok could not go back to old 2g sim. Rep gave me many reasons as to why it would not work after submitting it 3 time. The 3g sim I was using was new in early may replacing 2g sim. Insted of reverting back to current 3g sim I decided to use the sim that came with my g2x. I noticed that the contact area on the new 3g sim was slightly different then the old 3g from may. Both. Sims had that "T" code on the contact side. I guess it is time to test. Report more tomorrow.

Update: new 3g sim card a waste of time. Did a reboot and no data. I wish I knew where to look. Cm7 and miui seem to be a waste of time. I need wifi calling at home. Does any one have any ideas? Are their any developers willing to help? Is there some where or some one we can report this to?

Ive found the same thing as OP. WIFI started acting up when I finally switched to using the sim that can't with the phone. Never had any issues with the old one. When I pop the old sim back in wifi is perfect. I'm kicking myself now because I cant reregister my old sim because all the numbers are rubbed off.
FYI: try inserting sim in other device's. Depending on the device you can go into setting and read the sim card number. I used a @#$%berry 8220 Pearl flip. I wish you luck. I just tried to revert back to my old sim. They could not push it because it was inactive to long. Something like 30 days. Keep us posted.

Yeah just another update thread. Who here is still getting the no sim error after installing the update it is now worse for me! I am more of a reader and not a poster im just curious is there a work around for this like for example has anyone installed a rom and the problem went away?
LIttle Rant: I have had nothing but motorola smartphones Droid X, Droid Bionic, Razr Maxx so I got curious since the S3 is one of the top selling phones to check it out and let me tell you love the phone but getting that stupid error all the time is annoying I picked my s3 up thinking I could make a quick sell on my razr maxx but now im stuck switching back and forth between the S3 and the razr maxx Verizon even sent me a replacement did that help? nope now its been 3 days they have a ticket open so who knows any help would be apprectiated and lets hear your story!
I'm still getting it, even worse than before I installed the new modem (radio). It seems to be more prevalent in areas where it's switching from 4g to 3g and back. If I'm in an area that has a strong 3g or 4g signal, it never gives me that problem. Has to be a Verizon thing or something with the SG3 that can't handle the switching between the two modes, just not sure......

UPDATE: I can confirm that if I place myself in a particular position in town where my phone will constantly switch between 3g and 4g and I attempt to send SMS messages my phone inevitably drops all data signal and gives me the no sim and no connectivity message.
I haven't been to were I used to get them bad....but I got one in an area yesterday where I generally get a strong 4G single that I had never had the no SIM issue before.
I was not happy.

I am getting it all the time at my house sometimes to the point where the phone does not work at all but if I drive down the road phone works flawless no errors even at work no errors im starting to think it might not be the phone it could be there network but for the hell of it lastnight I switched back from my razr maxx at home and the phone worked fine and when I woke up phone was fine im wondering if this only happens when the network is more at peak operation im growing very frustrated with this phone might off it and just use the razr maxx or hope for another update.

I had the same situation just moving from one room to another in my house. Yesterday evening I received a text from my neighbor asking if I had noticed we were receiving a 4g signal in our area (we are in a rural area about 12 miles outside of Tallahassee, FL.). Since yesterday I have a solid 4g in my home area so the no sim problem has disappeared. But there are pockets of weak coverage areas on the way to work in town and at the Florida State University where I work and I continue to find small areas where the problem persists. It has to be the SG3's inability to handle the hand-offs between 3g/4g which produce the no sim problem. My Thunderbolt would handle the switching from 3g/4g much better and not produce the no sim error. I'm sure Samsung could remedy this with a software change (at least not display the no sim) when switching service.
I still have the error on 2 phones. Funny thing is it seems that now it is worse on my wifes phone where it was the other way prior to the update.
From reading this thread and similar threads/topics regarding the sim errors with the GS3, I figured I'd post this here. This is confirmed, my friend and I both have a GS3 bought on the same day at the same VZW store. She keeps getting a sim error while I have never gotten one regardless of coverage or 3G/4G switch frequency, I frequently switch from 4G to 3G when on the subway. She went into the store and requested a new sim card, wound up arguing with the rep, according to him there's no possible way the error could be related, she finally got a new card by calling reps at various levels. After doing a factory reset and reprovisioning the internal SD card with the new sim, she has not yet had a sim error with the newest OTA. So it seems many Verizon sim cards aren't necessarily defective, but are improperly configured with the VZW network. This is just an educated guess based off personal experience, hopefully this is helpful to those with frequent sim errors.

How do you reprovision the internal SD card with the sim? If you are correct, some people may be able to fix the problem by doing so with their existing sim cards.

I would also LOVE to know how to do this!!! Very frustrated with this!! Hopefully reprovisioning the sim finally works!!
After searching around, I found to reprovision, you need to go to stock and dial this in the dialar, *2767*3855#. My question is,
- Is it def not possible to do this from an AOSP rom?
- When they say "go to stock", can I just flash a TW based rom and do it?
reprovisioning does not work, don't waste your time

Agreed, I have reprovisioned before, to no avail. I thought it might be my SMS client, GO SMS, but I am getting the same NO SIM error with that client that I get with Handcent as well as the stock messaging client.
I called Verizon back today, to note my account that it's still happening, and spoke to them about a replacement phone. (I am already on my second S3 and second SIM) They offered me my choice of Android device, which currently is a bad deal. So I asked them if their deal would hold true once the Note 2 came out, and the nice lady at level 2 support said yes.
So unless this gets fixed prior to the Note 2... a switch is almost inevitable for me.
Dont waste your time doing the reprovision does not work I tried it earlier today.

Interesting...I might be doing the same thing. This issue is beyond frustrating. However, I have not called Verizon about it yet. Mainly because there doesnt seem to be a fix. I dont want a refurb S3 and there currently isnt a valid replacement. Might try the Note 2 if its possible.

call verizon just so that they can put a note in your account.
vzw put a note on my account and I should be able to just call up and replace my S3 with something new... just have to wait for something good to come out

100% agree with Ripken... call them and have them note it in your account. Basically, I am documenting it once per day (it happens more, but calling more than once per day seems redundant) so they see it, but more importantly, I have some ammunition if I finally move to a new phone. Today's call to 2nd level tech support was a bit frustrating to me, as the nice lady said that, in fact, verizon did get a bad batch of SIM cards. When I pointed out that the bad batch must have been sent all over the country, because it's not a localized issue, and there was a software update addressing it... she didn't have a response. We went thru the same rigamarole with the phone... ie pull the battery, read the number on my SIM, read the numbers from my software build, etc. Again, she offered me any Android phone in exchange, which I turned down. But, at the end, she mentioned she was sending this issue up to a different tier of support that (her words) works with Samsung to fix these issues. I kindly asked her to have them address the headphone jack - bluetooth non-coexisistance, which she giggled at but assured me was working as intended.
So, back to waiting for a fix... or an inevitable new phone.
VRLHD Modem
Ok guys try this at your own risk! I might have found a fix looks like there is another modem floatng around called VRALHD I just flashed it in odin and guess what my phone seems to be working good here at home so try this at your own risk!
Download Link:
http://goo.im/devs/invisiblek/i535/modems
also if you google VRALHD modem galaxy s3 something will come up I cant confirm for sure this will help I will report back after some usage between now and tommorow.
Here it is on rootzwiki
http://rootzwiki.com/topic/34053-of...zon-sgs3-sch-i535-odin-or-recovery-flashable/
Guess I had high hopes for that modem does not fix the issues nevermind lol I am hoping when the jellybean update hits with a new modem this will fix the problem the waiting game begins.
Installed the HD modem last night. I have one area at work that I can test it. I'll report back later with my results.
Update: Flashed the HD radio last night (in CWM touch recovery), install went fine. Didn't have an opportunity to check it out till this afternoon when I put myself in a exact known location where I could reproduce the 3g/4g constant hand-off with the "no sim" notification. Sent out 6 text messages and a couple of phone calls with no problem. Either this new radio did the trick for me or it may be coincidental that Verizon has corrected this "dead" area that would produce this problem without fail everyday I was at work. Couldn't tell you for certain. All I know is that it's not happening anymore at this particular location. I used to have the "no sim" "out of area" notifications constantly at my home until just last week when Verizon finally covered this area with a strong 4g service. Only time will tell as I travel thru areas that have weak coverage. It's very obvious that this problem stems from weak coverage areas and the SG3's inability to handle the transfers effectively.
This is my first time back in the world of Android use (as a daily driver) since 2013. I used to be a custom ROM-aholic, but now I just appreciate Android for what it is a mature OS that offers more flexibility than IOS. I wanted to buy a phone outright. And although they have more minuses than other carriers, I wanted to stay with Verizon.
I don't play games on my phone. The only time I ever found it to be choppy was when I used an app, albeit one that is actively updated, that did not play well with my phone. Headset Button Controller either doesn't seem to work with 6.0 or has issues with Moto phones. . It always did a nice job of playing non-google audio apps when then screen was locked. My all-time indespensible Android app is Dogg Catcher (yes, I am podcast nerd). I started having weird freezes on my G4 Plus when using the Headset BC app, especially when unlocking. Once I removed the app, the problems seemed to go away. Setting Dogg Catcher to stay alive seems to fix my problem.
One issue I have is with the VoLTE or what Verizon calls Advanced calling (a subset of a feature Verizon calls HD voice). Apparently, the phone supports VoLTE out of the box. I looked into the chipset specs. However, it seems that Verizon uses a non-standard implementation of HD Voice. Is that correct? I do not see Advanced Calling in my settings menu. I decided to try an ATT sim for kicks. I was able to get LTE (I live in an area with a strong ATT LTE signal). However when I went to make calls -- my phone dropped down to "H" -- 3G -- allowing calls and data. Yes, I know that ATT offers 3G calling / data simultaneously and verizon doesn't.
I talked to two senior level verizon technical service reps this week. Both essentially told me that every carrier implements HD Voice a little differently. The XT1644 phone registers in Verizon's database however, they are not showing that it supports HD Voice. I tried to explain to them that unlocked phones like the Moto X Pure, Nexus 5, and this one -- will not support the fullness of HD Voice, but can set to allow advanced calling. They told me that this wasn't available on their system yet for this model.
For some of you non-US G4 / G4 Plus users -- have you gotten VoLTE working yet? Will it really take a collaboration between Moto and major carriers as I was told?
I have Verizon. The phone supports and does indeed work on Verizon VoLTE. Settings > More > Cellular Networks > Enhanced 4G LTE Mode. Should be on by default. Works fine for me, allows me to call and use data over LTE at the same time.
AT&T does not support VoLTE on non-AT&T phones, so your calls will always fall back to 2G/3G.
At this time, yes VoLTE does depend on a collaboration between the carrier and the OEM. Hopefully that doesn't remain the case.

It was a huge fiasco for me with Verizon this week. One CSR told me that I needed a new SIM to get this feature. Local corporate Verizon store would not give me a sim because I was not adding a feature to my account and I wasn't buying anything. I end up talking to two senior level TSR representatives. One didn't really want to help me. The other one said she would submit a request to the "DSM" ( I may be spelling it wrong) department to have this feature turned on. She was supposed to call me back Friday and did not.
I am not wanting this for kicks, I can use this feature in my work. I tried the feature in Settings >> More >> and it does not show up.
Previously, I was using the 2015 (prepay) Moto E on my post pay account. That phone does not support voLTE. I am using the same SIM now. Verizon would not give me a SIM at _____ corp. store. I may go to another corp store if it will make a difference. Also, I cannot add HD voice / advanced calling online in My Verizon for this line.

Yeah, unfortunately not all CSRs are knowledgeable. Easier to turn to the Internet to look for help lol
Congrats on getting everything working!
I really wanted to US pre-order the G4 Plus 64 GB version and wanted to grab one on release day. I'm seeing way to many issues on connectivity, especially new customers. Verizon and AT&T would be new accounts for me. The issue of only a corporate store can hook up the phone with the rep placing the sim into a demo phone and things might work in a day or so by Moto rep on their main forum. For a $300 phone and a new service, case, screen protector that are all musts. They need to get their issues fixed. It wasn't a surprise this phone was coming out. I've been dealing with a junk no service at home scenario for 4 weeks now waiting on the G4 Plus. I work 12 hour shifts 3rd shift and I can't really find time to drive around back and forth and hope and pray a rep can do some twists and turns with a sim sadly

I've been dealing with a junk no service at home scenario for 4 weeks now waiting on the G4 Plus. I work 12 hour shifts 3rd shift and I can't really find time to drive around back and forth and hope and pray a rep can do some twists and turns with a sim sadly

This is an issue with Verizon, not with the phone. There isn't much Motorola can do about it besides get mad at Verizon.
There aren't any connectivity issues, the issue is rather with Verizon activating a new SIM card in the device. The workaround is not restricted to corporate stores, but corporate stores do give SIMs for free, while 3rd party authorized retailers make you pay for SIMs. If you're signing up for new service anyway, there's no need to drive around back and forth, just do it all in one go.

I know the whole situation and all the options as you basically just re-worded what I said in a few sentences. I've been on the official Moto forums. Not everybody has a working g4 or g4 plus phone right now. It doesn't matter if the phone working on Verizon is a Motorola issure or a Verizon issue. You still can't order a phone and pop in a sim card with a new account and have a working phone. I haven't had to go to a cell phone store to get a phone working in 9 or 10 years maybe longer. Even from memory when the Samsung Blackjack, Moto Razr and 09 IPhone (3g or 3gs can't remember) was plug and play. 2016 buying a phone and having issues from day 1 can't be tolerated from me or anyone else. All these manufacturers, companies, etc are getting clumsy and lazy. Especially the last 2 years. There was a time you could buy a phone and it have no bugs whatsoever. I've owned many phones like this. Maybe 6-12 months issues start to happen. Everything is rushed, From planning to parts to google OS to the manufacturer to the provider. Something seems to always be incomplete. Like lets release 5.0 with a whole bunch of issues so we can get some money rolling in and just release a update when we can. Connectivity issue to me is the phone not connected. Doesn't matter if its a full moon the cause of it. I can't go to Sprint or T-Mobile because the service at home/work is minimal. Verizon is the king in my city and at&t second but at&t pre-paid doesn't have options like there post paid (wifi calling, volte, etc)

The issue is not with Motorola, it's totally and completely an issue with Verizon's system. This issue affects any non-approved phone you bring to Verizon, not just the G4. You should really direct your complaints to Verizon, post on Verizon forums, etc. Motorola can't do anything about it, as they do not have access to Verizon's activation system.
Mobile hotspot
Does the mobile hotspot work out the box for folks with unlimited data or does it require rooting to disable the carrier check?

I have a UDP, hotspot worked out of the box.
One last question, does data and voice work at the same time? It does with my moto pure, but not my nexus 5x.

Yes, it supports Verizon VoLTE (which enables simultaneous voice and data over LTE).
How was the problem solved? Having the similar issues.
I'm performing research into an odd issue that may affect custom ROMs across multiple devices, and I'm hoping a few people can help me.
If you're here, you probably know that Sprint is a CDMA carrier. The SIM card is for LTE only, and so removing it should not affect ability to make calls, and the phone should still get 3G data just fine.
On my stock Lollipop Note 3, it works as expected; a notification bugging me to insert a SIM, but otherwise works fine with 3G.
I had a Samsung rep take the SIM out of his Sprint Marshmallow S6, expecting it would work the same... but instead it completely killed the cell radio. No connection at all, no phone calls, no Mobile Networks option in Settings.
On ports of Note 5 firmware, the phone will connect to the network for phone calls, but absolutely not allow mobile data to turn on. However, this seems to be because the source ROM is GSM only - the Sprint kernel and modem allow it to use CDMA, but the UI still can not fathom having mobile data without a SIM and simply disables the option. The same happens with an S7 ROM port (also from GSM-only source). With a lot of command line %&$#ery, I managed to make it use 3G, but only for about 10 minutes before it catches on and the phone has to reboot.
Now the question I seek to answer is whether the ROM port issue occurs because the source ROM was GSM, or because Samsung just removed the capacity for CDMA-only data from more modern phones. Once I know that, I can work toward fixing it. As such, I humbly request that a few people boot their Sprint Note 5's on stock(-ish) firmware without a SIM card, and let me know if they can use 3G like that.
Cheers! :fingers-crossed:
Newer phones have different hardware. The S6 and Note 5 need the SIM card to authenticate with LTE and with CDMA/EVDO. A rom change will never fix this. This is the next way phone manufacturers and Sprint want new phones to be built. The CDMA and LTE are one authentication.
Your Note 3 had the old way of authentication, where the CDMA portion was separate from LTE. Hence, when the SIM card was removed, 3G worked because the CDMA authentication was embedded into the device.
New phones will not allow this, and honestly, the only reason you were able to use Sprint CDMA without the SIM card is because Sprint has your device ID and let it authenticate for a bit, but then the network itself rejected you because there was no authentication mechanism.
That's... all really a wonderful theory, but the whole point is that current research is indicating it doesn't work the way anyone thinks it does. Even the Samsung rep was shocked that his phone behaved the way it did.
As of right now, I have located one Marshmallow ROM that will allow 3G to work perfectly without a SIM, but have not heard back from the dev on how; it's based off CM, which in my experience will not. The ROMs that don't, don't stop because of authentication issues, they stop purely because of a UI trigger. Otherwise just rebooting wouldn't allow it to be fine for another 10 minutes.
Hence, research. I know all about what it ought to do. And why, and how. I could write a paper on it. I want to know what it does. For that, I ask only for some kind soul to boot their phone without a SIM for two minutes.
That's because its not a theory. It's reality.
In a cdmaOne/CDMA2000 ("CDMA") network, the UICC contains a CSIM application, in addition to 3GPP USIM and SIM applications. A card with all 3 features is called a removable user identity card, or R-UIM. Thus, the R-UIM card can be inserted into CDMA, GSM, or UMTS handsets, and will work in all three cases.

I fried my SIM card when I first got the phone by using QPST to try to flash a custom PRL. Not only did the phone power cycle every 5 minutes, but it lost its entire connection to the network. No 3G, no LTE, no 1x. When i went to replace the SIM card, the rep went through about 5 cards until he found one that was actually a UICC card, as the others were ordinary SIM cards just for LTE.
Also, please don't tout research on XDA. Your research is at best an observation with one ROM, and my guess it was a fluke where Sprint didn't reject your connection. Research requires actual proof and peer review. One ROM working one time doesn't warrant research. This isn't an issue with a "UI Trigger" as you put it, but its just the new way phones are authenticated.
Try removing a UICC card from a recent Nexus device (6,5X,6P), it will lose all connection as well. Why? Not because of a UI Trigger, but because new phones need the UICC to authenticate both CDMA and LTE.
Finally, unless that Samsung rep was a Samsung engineer, he is just a salesman with little tech knowledge past what is needed to sell the device.

Similar issue with HLTESPR (Sprint Note3) moved to Lineage OS 5.8.2 can not make calls with SIM card inserted. Remove the card and the 4 works fine (no LTE). APN and Carrier show up in settings.
Replace the SIM card no APN's no carrier, no phone unless on WiFi.
I recently purchased an open box Galaxy S10+ G975U. Phone was in excellent condition. Was told it was an unlocked phone from Verizon. Upon receiving it, it had ATT Splash Screen and Apps. Was trying to get it working on Page Plus, and MVNO of Verizon. After much effort between seller and Page Plus, we finally got just about everything right.
We switched it back to Verizon Splash and Apps. We got everything working or so we thought finally with some APN changes. However, after using it a day or two, I noticed that during a phone call, LTE would always drop to 1X, thus making MMS and Data usage unavailable. Page Plus Customer Service is not good, some are better than others, but I cannot seem to get the issue resolved.
I recently got rid of the Verizon from CSC just to see if it would help and switched to XAA/XAA/VZW. Thinking it would help and it has not. My Galaxy S8 that still works with the same Sim Card with LTE that works correctly as well during calls, has a CSC with TFN/TFN/XAA.
I do not have the ability to switch to Tracfone (TFN/TFN/XAA) but don't really think that is the issue as Page Plus uses VZW devices.
Does anyone have suggestions or an answer as to what could be the issue? I have collectively spent at least three full days of my life between customer support and reading through all the forums and posts.
Thank you in advance to anyone who replies or has knowledge that may help.
