What apps or settings might interfere with carrier network connections? - General Questions and Answers

My carrier-branded, SIM-unlocked phone, when starting up normally, will - at first - not make or receive voice calls with the APN settings for the MVNO SIM card I have (mobile data works right away). I need to manually switch to the APN settings that came preinstalled with the phone (and which contain no settings except for the APN address of the carrier that I bought the phone from), then switch back to the correct APN. Then voice calls work. If I boot up in safe mode, this dance isn't necessary. Which would suggest that there might be some app or setting on the phone that interferes somehow with the proper functioning of the voice call function.
Not sure if this is related but I also note that the VoLTE setting is always greyed out (although it's set to "On") and I never see the VoLTE icon in my status bar though with the same SIM card, I see it every time I make calls on my other phone from the same manufacturer (Samsung).
I have posted the specifics of my phone in a previous post in the subforum for that model, see below. Any suggestions on how to trouble-shoot this?

Yeah, guess I'll have to do that. Such a hassle. Any suggestions on what sort of app to focus on first?

Like I said in my first post. The app also likely runs at startup. Be glad it didn't permanently alter a hidden setting...

Thanks, I must have missed your first post then. Makes sense.

No 3G icon or data connection

Hello everyone,
I got my Captivate yesterday shipped from letstalk.com. Everything with it has been working well, except I don't get a data connection with it at all, except WiFi.
As instructed by the sticker on the box the sim I am using is from my old phone, a Samsung SGH-A707 flip phone. The sim is a little over two years old. When the sim is in that phone, I get a 3G icon immediately.
I have tried turning the phone off, leaving it for several minutes, turning it back on again. Also removing the battery.
When I go to Settings, Wireless and Networks, Mobile Networks, Access Point Names, I see ATT WAP listed. I have tried adding another Access Point Network based on settings seen elsewhere in this forum which differed slightly by specifying a username and password, and not having the proxy and port set. But selecting this other APN has no change.
When I go to Network Operators all I see is an unselectable 'Default Setup' item. Others have reported seeing network connection information there, can anyone confirm on their Captivate?
Checking or unchecking 'Data roaming' does not seem to have any effect.
Under Settings, About Phone, Status the Mobile Network Type is listed as 'HSDPA' but Mobile Network State is 'Disconnected'.
LetsTalk are sending me a new SIM to try, but since I get a 3G connection on my old phone my suspicion is that this is a phone problem.
Does anyone have any other ideas though? Any help would be much appreciated.
Wow well you found something I hadn't yet. There was some talk about whether the captivate did hsdpa or not.. and according to the setting you looked at, it does. In that setting does it show your network is on aT&T? You shouldn't have to create a new APN, the default one should work. Sure you don't have the phone in airplane mode? I'm sure that's a stupid question, just asking.
If you don't have a 3G sim card I hear 3G wont work. You can get a new sim from ATT for free. Oh and about hsdpa ATT disables that Icon and uses a 3G one. I seen a test somewhere with two dif phones one with a 3G icon and one with the H getting the same speeds.

Nope, not in airplane mode, but thanks for checking, I'd rather you'd assume I was stupid than not ask me the question!

It is a 3G sim, at least that's what it is labeled as. Like I said I (apparently) got a 3G signal on my old phone. And a new sim is on the way.
on the sim does it say 3G with flames around it lol (thats how my last sim was and it was 3G)
I went to the ATT store to get my captivate. I had an old sim ATT logo with flames that worked in a N1, N97, Bold 9700 and iPhone. I too showed no 3G. They had to replace my sim and it started working. They couldn't explain it.

Great, that gives me some hope the new sim that is on the way could fix it, thanks!
I had this problem as well. This fix worked for me:
Settings > Wireless and network > Mobile Networks
Check both boxes
- Use packet data
- Data roaming
ATT / Captivate Android 2.2
Hope this helps,
Did you find a solution for this? I'm having the exact same problem with my Captivate. No 3G icon and no packet data connection or mms. When I try to go to a page it immediately gives me the "not found: check your data connection" page, and when I try to send a mms, the 3G icon appears like if it was trying to connect and send it and then disappears when the message fails to send.
I just updated to 2.2 today and I no longer have 3G as well.
just an FYI as long as wifi is turned on you will not see the 3g icon.
I have noticed that when you turn wifi off you generally will not see the 3g icon until you do something with the phone that requires data connections
Turn off wifi and try opening a website via browser...the 3G icon should pop-up automatically at that point

Hello sir, I tried this and now i have 3G(icon popped up and internet/mms works) but am i incurring roaming charges?
For me even that's not working, I think my stupid phone is broken.
When I got a refub'ed Captivate for my partner via AT&T online store since it was only $49, I followed the instructions that came on the box, and everything worked except no 3G/data. So thinking that it might be because of a refurb'ed unit, I called AT&T. They told me to bring it into a corp office store. Fortunately, there's one right down the street from me. I took it in, they fiddled with it for about an hour, including swapping 3 different SIMs, and told me that it was a defective phone. I asked then how do I get a replacement. The rep told me to contact cust service for them to ship a replacement out and it'll include instruction to ship the defective one back since they can't replace refurb unit there at the store. So I went out to my car, called the cust service. The cust service rep told me that I have to send the defective one in first before they'll send me a replacement. I got angry and I went right back in the store, grabbed the rep that was helping me out and told him to please talk to the cust service rep to work things out because I'm not leaving the store until it's resolved. So they talked on the phone for about another 30 min. Then they hung up. The rep fiddled with it for another min, then handed me the phone and the 3G/data was working. Appearantly it was the way that the phone was registered with the system, something was out of whack and 3G/data was not available for that phone line. I then recalled that when I ordered the phone from AT&T, I got an email with instructions that I had to follow, which I did, then I followed the instructions that came with the box. I didn't think much at the time, but it seems like the instruction was telling to do the same thing as the email's instruction was except it was via a slightly different way. So I think I might have inadvertly register the phone twice. In any case, when that happens, 3G/data is not available and yet, the reps checking in the system found the account was setup correctly with the proper plans, changed plans, swapped SIMs, and came to the conclusion of defective phone when the phone was perfectly fine. I don't know if this will help any one. But if your phone is not flashed or rooted, you might want to have AT&T check your account and phone registration.
Go to Settings -> Wireless and network -> Mobile networks -> Access Point Names. Inside that option go to Menu -> Reset to default. (Reboot your phone)
Worked for me, i have a samsung captivate thats rooted running on 2.2 froyo and i was deleting some user data,believe it was dialer data (do not delete that, it also deletes your texts) and i all of a sudden my internet stopped working,i tried every setting and i even think there weren't any APN in the list of APNs because of deleting rampage, so i reset my phone and after that i reset the APN back to default settings and rebooted my phone and it worked. For some of you guys, if it still has an APN(the cingular one) in the list of APNs then all you have to do is reset it back to default by clicking menu with the menu button on your phone and click reset. It should work.

[Q] HTC One E8 bought from Etotalk APN issues (AT&T)

So I bought the HTC Once E8 from Etotalk, which came with all the Chinese apps removed and the Google Play store added. I went to the ATT store to get a nano sim, and calls and texts work just fine. My issue is with the data connection. I have done a lot of google fu, and have tried the same settings that people are using for UK M8's but am still having issues. From my understanding the bands are supported, so It should just be a configuration issue.
Would anybody be able to shed some light on this for me? This is my first overseas phone, and I have only had experience with vanilla Android installs to date.
Also, the first thing I did was install the software update from HTC, which probably wasn't the smartest move. I don't see how this would affect APN settings though....
Let me know if any other info is needed, thanks in advance for any help!!

You probably lost the etotalk modrom while updating, but that shouldn't be a big deal. Though it may have overwritten the predefined APN settings?
Did you manualy check your APN settings under settings --> mobile data --> sim1 --> access point names?

Yeah that's what I think happened, is that I lost the modrom. I wouldnt think that would affect the APN though, isn't that supposed to be unique to each country, or something of the sort? I will send Etotalk a message and ask them if there's a chance that could be it anyways.
I have indeed tried keying it in manually, trying every combination from default, to the one I got from the ATT rep, to the ones I have found online from different forums.
Fixed
I tried using the legacy cingular APN. Apparently my grandfathered unlimited data plan was on these old codes, ie. 3G only...
Thanks anyways.

Is there any way to make IMS settings permanent or stop Android from auto discovering IMS settings on boot?

So, I've got a Galaxy S10e, with a model number G970U1, and the entire reason I bought this thing was so that I could use voice over LTE on AT&Ts network - it was one of the model numbers listed that was supported by AT&T, however, the phone itself, while being brand new, was originally a Verizon phone, as the phones CSC states that it is XAA/XAA/VZW. Upon insertion of my ATT sim card, the phone did not adapt to being an ATT CSC, even though it has the OYM software that should have the ATT CSC in it. I have tried a ton of things to try to get it to switch CSCs, from flashing an ATT CSC in Odin, to just doing resets with and without the sim card in, to literally paying $35 for Samkey to try their CSC changer, but simply doesn't work. nothing I do will get this thing to switch to the ATT CSC.
Anyways, as a consequence of not running the ATT CSC, VoLTE does not work. ATT has already provisioned the phone for VoLTE but the phone simply doesn't automatically acquire an IMS registration upon boot. I've discovered after many hours of trial and error, a way to make VoLTE work, but I can't find a way to make the fix stick between boots. This is where I'm hoping somebody else can come in and help. I'm looking to try to get the phone to stop automatically discovering IMS settings since I think it's this very auto discovery that is causing my fix not to stick.
Here is what I have to do every time the phone reboots to get volte working:
Open Alliance Shield X, go to App Manager
Search for IMS settings, click it, go to activities, and then launch the IMS settings menu with the first activity in the list.
Go to the IMS service settings, upon clicking of the IMS service settings, ALL of the toggles for RCS and MMTEL will be off and the upper left corner says "ATT US" - I toggle all of the toggles on and wait about 10 seconds
Go to settings, about, sim card status, and at this point my IMS registration status should have gone from not registered, to registered, however, VoLTE still doesn't work at this point.
Switch back to the IMS settings menu, go back a page and then click "Reset to default" to reset all IMS settings to default. Here is where things get strange - at this point, the IMS settings menu will claim I am using the T-Mobile IMS settings - but at this point my IMS registration status will remain registered, and VoLTE will work properly until I restart the phone.
I want to try to keep these settings, but like I said, once I reboot the phone, it gets the ATT IMS settings and VoLTE will refuse to work, and my IMS will not be registered.
Any advice?

Do you absolutely HAVE to have ATT? You would likely get better results with T-mobile.

Not necessarily, but the issue is that I've got 6 lines on AT&T, with some of the phones not being paid for.
You might try this method. Download the Latest same firm tool. Hit this tool is basically used for removing the FRP lock on phones, and it actually does work for that, but one other feature the program has is the ability to change the CSC code on your firmware. Which it did successfully, until the phone was rebooted and then it locked back on to AT&t. So the trick I think would be that after you use the tool and before you reboot the phone do whatever you're going to do because it you can change it to xas or xaa in which case it's unlocked and you should be able to manipulate it. I have never actually done this but in theory I think it might work good luck brother keep fighting the good fight

Question Lack of Verizon Compatibility

I installed a Teyes CC3 unit about a month ago. I have a Verizon unlimited data plan and hotspot so I was using this combination to receive WiFi. It was a bit inconsistent so I called Verizon and negotiated a good monthly rate for an added android tablet line. I picked up a sim card from Verizon and installed it in the sim card slot as shown in the Teyes direction or what appeared to be the sim slot. The unit indicates 2 sim slots but I could only locate one. The exposed sim slot was poorly installed and it was tricky to insert the sim card. I now wonder if the two sim slots are hidden behind the perimeter trim? After installing the sim card it did not show up on the sim card interface. I called Verizon to activate the sim card to confirm it was properly installed and the rep. stated that Verizon does NOT support the Teyes android unit! Question: 1. Could anyone confirm if they have been able to connect to Verizon with a Verizon sim card? 2. Is the sim slot(s) visible on the unit or are they buried behind the plastic trim piece. Thank you
Does it have an external sim reader.The joying I have has to have the card all the way to the right on the reader for the unit to pick up the card.I am also trying to get onto the Verizon network, but no dice. I had to trick the network into thinking my unit is a phone for them to give me service, that's as far as I got. Still playing with the APN settings, but nothing get.
Did you ever find an answer to this? I have a verizon sim card as well. Shows 4G but no actual data
Didn't pursue this further after Verizon stated they don't support the T'eyes unit. I just use Hotspot on my unlimited data Verizon plan. I downloaded a Hotspot Automatic app so with Hotspot activated my phone automatically connects to the T'eyes when I turn on the radio. Works fine.

What app did you use?
I don't think these support VZW radio bands.
Just set mine up with VZW, so I was wrong, it must have been my USMobile SIM that didn't support VZW network.

App is HotSpot Automatic by Christian Heinisch
See, I still want this to work without my phone hotspot because I'm not the only one who drives the car (and/or has an unlimited plan).
I have a spare Verizon sim for the summer that I'm parking (Visible, my kid is going away to camp) and I notice that when I put it in, I'm getting bars, and a 4G/lte icon. It is connected to the network, but I think the APN just won't populate and it won't let me set it manually.
If it didn't work, there wouldn't be bars I think. I mean, it's obviously registering itself on the network. I've used this sim in plenty of "unsupported" phones before, as long as it supports the right LTE bands, Verizon is basically a GSM carrier now. They will tell you otherwise, but even GSM unlocked phones seem to work in my experience as long as they are activated elsewhere first.

Sorry, you can try googling the apn settings for your carrier, or maybe put it in an Android phone. Or contact your carrier and ask them. There isn't really a network-wide setting that we can give you. I can tell you what I used on my visible line, but it's different then page plus or Verizon post paid or any other Verizon line would be so I'm not sure how useful it would be unless you're also using Visible.
I was able to get internet working on my Teyes CC3 with the following settings, although I will mention that I had to use a 3rd party APN app to unlock the edit function as default it is locked through the android interface.

The settings did save. I rebooted the cc3 unit, and I had data and continue to have data. I did want to try editing the settings a bit, but I noticed when I opened the app and opened the APN settings, that they were blank, despite that my APN settings were still saved in and working in my unit. So yes the settings did stick, I continue to have data and it works perfectly fine, except if I open the app and try to view the settings they will display as blank as if they are not there, but my unit is working!

volte missing in Samsung s8

I do not have very good reception where I am, so I started looking for things to help. Got a booster which wasn't much help. I then thought voice over wifi, so I checked if the s8 had it and yes it does, or so I thought. Voice over WiFi did not appear anywhere in my settings, my Telus provider was baffled as I was. We have been on the phone for hours. I with guidance backed up and factory reset my s8. This brought in an app under settings>Apps>more>show system apps and then scroll till I came to WiFi Calling. This appeared with the reset. Apparently something like that should appear in the phone app settings and have a switch, Mine does not. Then I discovered there were codes and service mode. Under code *#9090# I found a setting that reads "VoLTE Weakcell Setting.
My question is please if anyone knows how to implement WiFi Calling on s8 I would be grateful. God bless.

Typically, VoLTE functionality is controlled by your carrier in their system.
This is how it normally works:
1) your device must support/offer VoLTE service
2) your carrier must support VoLTE
3) your carrier must support VoLTE on your specific model number
4) your carrier enables VoLTE service to your device in their system somehow or they send you a specific SIM to enable VoLTE.
In other words, VoLTE support and functionality is more controlled on their end than it is on your end.
Yes I understand, when their tech support says s8 should do wifi calling, and the settings dont appear where they should, and then after a reset an app called "wifi calling" appears in the app list, but nothing anywhere else. Except, as I was able to find, there is a service mode and there is a selection there that is called "Weak Cell Settings". Sadly I dont have service programming manual. Thank you.

It could be that the network supports S8 but doesn't support your specific model number of S8, especially if the S8 that you are using is not the same model number as the specific model of S8 that they offered/sold on their network, if it's from another network and has been unlocked to be used on other networks, it may not be a specific model number that is specifically supported by their network. If this is the case, the specific model number(s) of S8 that they support would have a firmware that has the settings in the correct place but the firmware on your specific model number might not have it. Not all model numbers are equal, the firmware on each of them is designed and built by the specific network that it is branded to, with each if them having differences intentionally chosen by the network that is branded to, including what settings it has or doesn't.
Hi Everyone
Thank you for your help. Problem is solved. It is a service setting that sets the retail company selling you the phone and /or the plan. In my case I had a phone which my provider did not program when I began a new plan with them. all companies are listed and I guess the program for wireless calling is included with your selection of the company....phone responded immediately with all the proper programming. Thanks again for your time and effort

I've never known a device to have that setting. If your device is an international model, it would make sense to have that setting for the various regions/carriers.
