Lot's of questions. One at a time. One thread. - Verizon Samsung Galaxy S III

I recently left the United States, and now my phone isn't working as smoothly as I would like it to. So, now I have lots of question. I also missed the 4.3 OTA update, not sure if I even really need it from the flyer I looked at on VZW website. First things first.
I arrived in Buenos Aires 2 weeks ago and signed up with a local service called Claro, got a chip, found APN's and was online. Pretty smooth. However, I was stuck on the Edge network. So, after almost 2 weeks of pulling hair out and searching on the web for the problem. I called VZW global services and they told me that Claro is who they use for there PRL (preferred roaming list) and that if I use Claro's service with my VZW phone I will be locked in Claro's Edge network and never get 3g or HSPA+. They told me to use a different service in Buenos Aires if I want to get 3g or HSPA+. So I cancelled the Claro service and went to the other companies and their plans totally suck. None of the plans here are really that good, but Claro had the best plan for me.
My first question for this thread is, if I root my phone will it remove VZW's PRL from my S3 and allow me to get Claro's 3g and HSPA+ connection, or is there a way to remove the PRL?
Please help me figure this stuff out. I'm seriously tired of digging through forums. I feel like I have been devoting so much of my energy to a silly phone. :cyclops:

I don't think rooting the phone will get you anything new related to phone service, roaming, or priority access lists.
I don't know much about how PRL's work, but rooting your device might be the first step needed to tinker with embedded phone settings and flashing roms that might do what you need.
I found this: http://www.androidcentral.com/how-update-your-prl-your-cdma-device
may not apply to S3, but could be useful.

Thanks for reply.
I did some reading on PRL's, so yeah, I don't want to mess with that stuff on my phone.
I went to another carrier here in the city and I'm stuck on the same network, Edge. Basically I'm back at the same place as before and I was fed some bull**** from VZW global support. So, I called VZW global support again got totally frickin' nowhere! I should of bought an AT&T phone I wouldn't have this problem right now. [email protected]#k VZW, they sell a product and call it a "global phone" but then it has limitations in other countries, that's not [email protected]#cking "global." God bless corporate America! So fed up with phones right now, I was so much happier with a flip phone.

i dont believe g2x has 850mhz UMTS HSPA

I am from Vancouver bc. I am on the Bell network. Which operates from HSPA network only. Rogers is the only provider in Canada to have both gsm/edge and HSPA networks operational.
I bought a g2x, branded tmobile on the front itself and unlocked from a trusted source that I have repeatedly bought phones from. I get a new android cell phone every two months or so. Im familiar with setting up apn and so on.
The bell sim I use cannot find the bell network upon any kind of search. I can only find Wind and Mobilicity networks and they are AWS. I've tried reseating the sim and so forth, all fail. The sim works fine in my unlocked at&t atrix and Telus milestone.
I borrowed a rogers sim and it was able to register on the 2g network only. I entered the rogers 3g apn but it would disconnect when I put it on wcdma mode. Im convinced that either I have a broken umts radio or a faulty unit or tmobile screwed up. Looking for suggestions please and thanks .

imma keep this too about 3 lines if i can....
it has to have 850mhz its stated by the FCC that it does... (google specs)
and if it didnt... tmobile would have a law suit.... please if you will give us this "trusted source"
and when did you get the G2x?
I'm sure Tmo didnt lie, the phone has to pass the FCC in the US for the bands they will use, so Im sure Tmo knows what bands it's capable of. they wouldnt mismark the box.
Sounds like whoever unlocked it didn't do it properly maybe.
interesting...
only reason i was interested in the phone was the fact that it supported UMTS HSPA and AWS. wanted to use it on rogers but also wind down the road.
I got it this afternoon. The source is a guy I know that buys devices from the states and brings them up to sell. I bought several phones from him his year. I only wish this worked. The unlock definitely works or otherwise it wouldn't work on ROGERS' edge network.
when you put in #*#*4636*#*# into the dialer, what options do you have under Phone Information?
any options for WCDMA only?
Are there any *# codes that have been figured out for the G2x that might get you to a "Select Bands" menu? Maybe all you need to do is find a special menu and turn on the bands.

not to call you a liar but even if your "source" ordered the phone friday with the saturday shipping... how the **** did you get it through customs in one day?
just dont understand how you got the G2x unlocked from someone that buys them in the states and had it shipped so fast....................................
i shipped a 3 oz package to Toronto and it took 4 days... FROM WISCONSIN?!?!?!?!?!
Since ATT and Tmo haven't merged yet it could be locked out of the baseband right now too- to be unlocked by a software update after the merger.

if the merger is even accepted... LG would do all the hassle to lock a baseband till a merger happens that might not happen for 10000 reasons

Well that's the point, its still a year out at least. There'd be no reason to have a carrier branded phone unlocked to those bands yet until if/when it does happen.
If so it was a Tmo decision. And itd be a simple radio update in the form of an OTA update to unlock the bands, nothing too major.

very true but most phones/devices that carry dual basebands are not locked to a carrier that i know of
There are lots of variables though. The baseband software may have just not been ready yet. They may want to keep it locked pending approval of the ATT deal, merely was put there are a precaution to not have an outdated device if it does go through.
Too many variables, but it for sure has those bands. Anyone can go to the FCC page and look up the tests.

but i wanna know how this guy got a unlocked G2x from a "source" in the us so fast... faster than anyone of us ordering it.... (mine comes tomorrow when the sun is highest in the sky)
@dgr8one, let me check that out in the dialer.
@nate420, iwish I knew how he got it up so fast. I confirmed with him Sunday morning that I wanted it and he said unlock code probably be ready by Wednesday. Then he texts me today to say it's ready. Lol

damn must have held someone at gun point to get it the 15th lol <---- joking
It's too early to freak out, one person in Canada's having an issue with one G2X. T-Mobile would be insane to advertise the phone as quad-band and allow the media to report it that way if it's not really offered. If they didn't advertise it, but it had the capability, that would be another story. I'm sure a bunch of people are going to try and use it on AT&T over the new few days/weeks. Let's see what happens then.
I sincerely hope that whoever ordered for at&t purposes that it's only my device having issues.
I tried the #*#*4636*#*# but it only shows "mobile network not found ". My sim card is in there. Perhaps they will unlock the basebands somehow on the 20th.........

Question: Sprint Touch Pro 2 be activated on Verizon

After much searching I found lots of 'no you can't's, but I haven't found any posts that are recent, ...in the last 6 months.
I have a Sprint Touch Pro 2 that I successfully got working on Page Plus. I would like to get it on my folks' Verizon family plan. I called an agent and they said if it doesn't have a Verizon logo on it, it's not possible.
I question this, but I've found no one of late posting about this.
I think the phone will work on Verizon, it may just need the ESN number activated on their network.
I remember someone here or at PPCGeeks activated it for me on PagePlus, is there anyone/any way to activate it on Verizon?
I like the phone, I just don't need data, so I don't want a regular Verizon phone.
thanks,
Yes, you can get it activated on VZW... The only problem is this... you can't do it legally or ethically... It would involve doing things against VZW's rules as well as the law... and you would need a "broken" TP2 (or other VZW phone) to do it... But that aside... the reason it worked with PagePlus is because they allow outside phones on their network, with giving you the responsibility to make it work on their network.. VZW is vey explicit that they will NOT allow anyone elses phones on their network (same with Sprint)... They are the worse 2 when it comes to that IMO..... Sorry to the bad news.... But sometimes that is how it goes.... Maybe you can post an ad on here offering to trade someone yours for the VZW version.. or maybe Craigslist?
Thanks,
Trading for a verizon phone won't work, as then I'll have to get data.
My bottom line question:
I need a smart phone, but I NEVER need data, wifi is always available for me. But I guess there is no way to have an Android phone on a Verizon network, without a data plan?
Not legally anyways, that's one of the downsides to using CDMA, the carrier has much greater control over what kind of phone you use. Thankfully they can't control the Rom/OS you run on it .
You need a Verizon rep that knows what they're doing, it can be done.

[Q] Would it work on nTelos?

Does anyone here know anything about the regional carrier nTelos and its' CDMA network? I'd love to get the Nexus 5 but I'm not sure it'll work on my carrier.

I wouldn't bet on it. They may register it for text and talk, but getting data and mms working has always been an issue. It can be done, but it's a lot of grunt/guess work

Thanks. I was afraid of that. Do you know of any reliable way to set APN's on jellybean or KitKat?
nTelos has LTE launched in a few markets, and now they are selling LTE devices in Richmond even though the LTE network isn't up. (Phones are running on 3G). In theory, if the device is unlocked, you should be able to put an nTelos LTE SIM in the device and it should work. (I went by my local Richmond store and got a SIM card for my iPhone 5 and upgraded my wife's S2 to a Moto X). I can switch the SIMs back and forth between the two devices with no issues. I am trying to find someone with an unlocked N5 here in my area to test my theory, but the only person I know who has one is on T Mobile, and we work opposite schedules, so it's almost impossible to meet up.

Thanks so much for your info! I knew nTelos was launching LTE sometime but here in WV it'll be years before we see anything. If you do find that it works and you have time could you report back? I would really appreciate it.

You might not have to wait as long as you think. nTelos has launched LTE in Bluefield and Bexley in WV. The person who I spoke with also said that the remainder of the network should be launched by EOY 2014. I saw on an investor relations report that the actual claim is 70% POP coverage. The rumor that the rep told me was hopefully June/July for LTE here in Richmond.
I'll keep you posted on the N5!

Once you do meet up, the T-mobile / Unlocked aspect shouldn't really be an issue as the T-mobile device is the same unlocked device that everyone else in North America has. So far, no locked N5's have turned up

Well, that's positive news! nTelos uses band class 10 for CDMA and LTE bands 2, 4, and 25, so in theory, when an nTelos SIM is placed in the phone, it should register and work without issues.

Yep, but theory and practice are 2 different things
I do like the snap dragon 800 though, meaning there is only a requirement to have 2 devices worldwide. I'm pretty sure soon, qualcomm will be able to support more than the maximum 7 on one radio chip and maybe soon we'll start to see one worldwide device per release. That would be great. Until some other country decides to shun global standards and invents their own band

Exactly. Hopefully it will work though because I am interested in getting an N5. I have a nano SIM in my iPhone 5 and my wife has the same in her Moto X, but I do have a SIM adapter so, barring any setbacks, I should know this weekend if it will work.

Well that's great. I just didn't figure we'd get anything soon because even AT&T doesn't have LTE here yet. I'm really hoping what you heard is true though. Thanks for keeping me updated. :good::laugh:

I do. I am an nTelos dealer and flasher with my own flashing site going live as we speak. It can be done if you have CDMA workshop, otherwise I take mail-ins.
That's awesome! Link to your site? I'll check out when I can. I actually do have CDMA Workshop but no idea how to use it or what all I need to set up on the phone with it. I was afraid to go ahead and buy the phone because I didn't know if I could get it working.
Ok... So I had a friend attempt to try a Sprint variant of the N5 which he got at Best Buy... No dice. Couldn't figure out the carrier settings and it wouldn't make calls either. I tried a Play Store edition yesterday... Also, no dice. Same situation.... I have another friend that works at T Mobile that is going to grab one for me to try. I'm not giving up hope!!! I'm sure there is a way to get it to work, but when you go to network settings, if only allows you to connect to AT&T, Verizon, Sprint, T Mobile and 311 660 which I think is Metro PCS. There has to be a way to change the settings to be able to recognize the nTelos SIM card. The N5 supports CDMA Band Classes 0/1/10 and LTE bands 2/4/25, which should cover nTelos.... Not sure if the device is domestically locked to those certain carriers, and the international version would be a better try (I think it is only GSM though), but if someone can brainstorm a work around, I'd love to hear it!
Ok... Here we go... I might have stumbled upon something here on XDA that might help us out. I'm still researching it, but I wanted to post my findings here so that if anyone else s interested in looking into it, you can. You may have already seen this, and someone here commented about CDMA Workshop, and that is involved, so maybe (s)he could chime in and give us a helping hand as well?
The first link I came across was:
http://forum.xda-developers.com/showthread.php?t=2619312
This looks to be a trial and error guide. I MAY be able to get my hand on some of the files that may be needed with a little digging around and some schmoozing with nTelos employees, so we will see what happens.
I posted in that thread to see if it will only operate on CDMA, or if it will switch over to LTE when it goes live (as long as there is a sim card in it). Waiting on a reply, so hopefully we will hear something back soon!

Ok well good deal! I hope you can get it working. Little word of advice though, all the phones are the same. Sprint, Play Store, doesn't matter they're the same.
Ok, well, I have gotten my hands on a Verizon S3 (boo for the locked bootloader), and when I throw my nTelos SIM card it in, it works for talk and text immediately, which isn't surprising, b/c the device is unlocked. You do get the Non-Verizon SIM message in the notification bar though. Well, anyways, I was able to take my jailbroken iPhone 5 and use an APN editor and recover the APN settings for it. I entered those into the S3 and BLAM! It worked! Data kicked over immediately!
Now here's my thought process... The S3 took the SIM for talk and text without issue, while the N5 wouldn't even read for that.... Even though the N5 is supposedly unlocked, could it still be locked down to the bigger providers, and not allow a SIM card from a smaller carrier, such as nTelos? I have heard of rumors of AIO Wireless SIM cards working, but that is an AT&T MVNO. I haven't seen anywhere posted that someone from, say, Alaska Wireless, or Cspire, or Republic Wireless using the N5.
Now, if there's a way to "unlock" the device to work with additional carriers, that would be great, but I'm not sure where to start even looking for any of that information. most comments you read about the N5 state that it is unlocked to use anyone's SIM card, which obviously isn't true. The phone seems like it wants to pre-configure itself with the SIM card. I did see a thread somewhere that people are able to get the N5 to work on Straight Talk on LTE with redoing the APN settings.
I need to get my hands on another N5 and replace the APN settings with the nTelos LTE APN settings and see if that works. If I can get that done, I'll let everyone know!!!
Ok... Here we go again... I'm posting here more of a "think out loud" type of post. I was digging through the Nexus 5 Q&A thread, and I came across something that might help out. *#*#4636#*#* That is supposedly how you get into the settings for an LG device to be able to change it's network type. I'm wondering that since I missed doing that with the last one that I had my hands on, if that might be why it didn't read my SIM card. I went by my local nTelos store last night to see if it worked on all LG devices since they have the F7 on display. I was able to go in and change it while I was playing with the phone. Some of the settings completely borked the reception, which is what I was hoping, but others worked just fine. I'm going to try and go by a local Best Buy later today and try it out on a display model there to see what I come up with. I'll post back here once I figure something else out.

[Q] XT912 change from Verizon to AT&T?

Hello,
New here, don't see an up to date thread on this issue. I moved and Verizon has no towers here, so I had to cancel. I'm lucky to get a single bar of 1x or maybe 3G. Then it cuts off. Anyway, AT&T is about the only choice here, tower coverage wise, so I was looking into it. I popped in an old SIM card from a friend's AT&T phone, and it recognized it, didn't seem to request an unlock code. My contract has been up with V for months, not sure if that has anything to do with it.
Poking around, seems like basically the issue is some providers use GSM towers (like the rest of the world's standard) but a few like V use CDMA. This info seems a little outdated, probably because not a lot of folks care about the older Razrs anymore. AT&T seems to have upgraded a lot of their service to LTE now. I might pop into AT&T tomorrow to see what I can come up with. My GF has a family plan thingy going so to add this old XT912 would only be another $20 / m.
I just thought I'd throw it out there, and ask you guys what sort of problems I'm going to have? I've read I might get signal, but no data. I've read that the physical radio operates on a different frequency and might connect to GSM but might not be stable. Just wanted to hear your thoughts in laymans terms. I'm pretty new to phone modding, but it's interesting for sure.
Thanks for any attention.
Just looked up more about the physical issues with phone radios. Stumbled across this app named GetRIL
Read on other sites that some phones are Radio Interface Layer locked, which I think is just the physical limitation of the phone. After the FCC changed some things, like forcing carriers to unlock phones after service is complete, most newer users won't have this issue. Anyway, it's interesting reading.

Question An A52 4G Dilemma

So this past summer I purchased a 4G version of the A52 from Amazon, my main reason being it was cheaper than the 5G. Now I'm finding that this choice may be affecting my carrier situation. I am in the United States, and had Cricket Wireless at the time of purchasing the phone. It worked for about 4 hours, then the service quit on me. Apparently Cricket claimed that my phone did not have the proper technology, blah blah blah, something to do with the discontinuation of 3G and or VOLTE. This obviously does not make sense, since this phone is from 2021 and would not be made with old tech. Anyway, I got them to turn my sevice back on, after it being in a "suspended" state. It was still working for a while, and then some time in september I think Cricket sent a text to me (and my fiance as well, also has a phone cricket doesn't like) saying that they would start redirecting our calls to customer service to get us to "upgrade" since the phones would supposedly stop working completely in February or whenever 3G is supposed to go kaput. So, we switched to Mint, who claimed that our phones would both work on their network, and they did, except that the service sucks, even while being in a modest sized city. It also has little to no service at my work, and I'm convinced that T-mobile's service, at least through Mint, absolutely sucks.
So, my question is, what do you all suggest? Does anyone have this model, and what carrier are you with? What kind of luck (or lack thereof) has anyone been having?
Sorry if this has no place here, just doing all I can to get some answers
Well, I don't think I have a clear answer to your question, this is something that I found very very weird. I handed over a Galaxy S9+ to my fiancee who's carrier name I forget, I think it also got acquired by T-Mobile, but I'm not 100% certain. However, the phone didn't work properly. I can't remember what problems exactly it had but they were network related. Turns out that if you're going to change phones you need to go to a store for them to configure it and change it in their system. Otherwise it will either not work or not work properly.
And this was also the case with her sister who bought an unlocked, Mexican phone and she also had to take it to the store for them to configure it. It would have these problems unless she took it to them.
You would assume that all you need is to insert the SIM and it would work out the box but I don't know why this carrier had this method which just makes everything so annoying and complicated when it doesn't need to be. Oh and this isn't a one time thing, every time they changed phones they would need to do this! So you should probably look at going this route, it's my best guess.
EDIT: Oh and also before we knew this, we had also purchased a Galaxy Note 3 (which yeah it's old, but had 4G when I used it with my carrier and all of a sudden it turned to 3G when used on her carrier) so we ended up giving it away. So it was definitely a carrier problem. It was so annoying.
