This, it is the only way. I have heard that T-Mobile will give the codes out if you say that you are going out of the country for a vacation or something of that nature.
Also, the T-Mobile version works with ATT's HSPA+ data, but not the other way around. Just so you know.

Sim unlock would be the way crazy vato as mentioned above.. however, without the correct xml files you'll never get 4gee or mms capability... You can set the apn and get interwebs but mms will be a diff story... I just spent a ****wad of time moettling with a att windows mango phone and got lucky enough to somehow make the xml files writeable to change them from att to tmo... Good luck holmsdog.. let us know the result..
Also, make sure the s3 even supports the upper end frequencies needed for the mms support dudeholms

Straight talk with One S and changing apns

Sent from my SGS3

So I bought my son straight talk pre paid plan for his tmobile one s. Where we live straight talk uses T-Mobile as a carrier. Right now he is visiting his mom for xmass and the area he is in has straight talk but through at&t. Can I change the apn settings to make his tmobile straight talk work on at&t straight talk? I did try to change his apn settings to at&t straight talk and the apn wouldn't stick. He's running Zen Rom. Also I never updated the hboot. It's still below v .13 (that iterations not right but I think u guys well know what I mean.) Thanks for the help!

Hard to say. I also have ST but I unlocked my phone and am using the micro at&t sim card. I'm not sure exactly how it works buy considering there's a at&t and TMO sim card. I think it works with the network the sim card is associated with. I could be 100% wrong but I may also be right.

Thanks for the reply. I'm going to give ST customer service a call. How lame though tmobile ST doesn't work on at&t ST. I asked at the store where I bought the SIM card and they said that they only sell ST through Tmobile in the twin cities... oh well maybe I can get it online or just change to another at&t prepaid.

Hopefully CS will give you some good info. They are never too helpful when i call in.. Not sure if it'll work but maybe order an at&t sim and just switch out which ever sim with the better coverage is.

Hi everyone!
I just got on to ST with a t-mobile htc one s and am using the APN given on the sheet that came with the sim card. My emails are coming in just fine but when I go to send or attempt to download a picture text, it fails. Can anyone tell me what they have used for their APN? I was also curious if maybe the locked tmobile APN's are having something to do with the fail. Anyone know how to get rid of them so I can create a separate MMS APN?
THANKS!

What Rom are you on? If stock Sense what version? Also are you using the TMO ST SIM card or are you unlocked and using AT&T?

Just noticed actually that the ST APN isn't sticking. It keeps going back to the locked TMO APN. The version of Android I'm on is 4.0.4. I just tried to use the app APN Lock, but it states that Android versions 4.0+ don't allow it to work. I'm using the TMO ST SIM card.

I'd definitely recommend you unlock your bootloader(if you haven't done so already) flash recovery and install a custom Sense Rom or maybe even give a AOSP Rom a try. I personally just installed LiquidSmooth Rc1.5(AOSP) And when I booted up the ST apn was already there and selected..
All the necessary tutorials and roms are located in the Development Section.
This all assuming you haven't unlocked/rooted your one s before

Thank you for your reply! I really appreciate it!
I haven't rooted it or done anything with it. I'm a super total noob when it comes to this stuff. Before this phone I had a blackberry forever and a day so I'm a bit lost.

Using 3G data in Europe

So I'm looking into traveling to Portugal this summer and I'm wondering if I can grab a 3G data only card from Vodofone and pop it into my S3. I know the phone needs to be unlocked for this to work and I have seen a long involved tutorial on here on how to unlock the phone, but I've also heard Verizon will unlock a phone for you if you are a customer in good standing. Is this true? If I can get Verizon to unlock my phone should I theoretically be able to use this data sim card in Portugal?
Also, I know Vodafone lets you make calls to other Vodafone users for free, will I be able to do this if a get a sim card with some prepaid data on it only? Am I still considered to be on Vodafone's cellular network?
Thanks so much!
As a side: If anyone has an experience with Vodafone's 3G in and around the Lisbon area let me know how it is!! I'm mainly looks to tether my phone to a laptop and do some development work while I'm over there.

Would you happen to have that link yo the process of where you can unlock the phone? Or you just mean the process for changing the apn

I'm pretty sure the thread they're referring to is the GSM travel thread. If using a JB TW rom, one just needs to edit the apn's like you mentioned.

Got it, thanks!
I've also heard that the Verizon GSIII does not have the radio's for internation GSM 3G, is this correct?

I would say that's incorrect given the thread I posted which contains plenty of user experiences contradicting that statement. I'm eager to do this myself if I travel again this year.
The primary thing you just need to do is have an international sim and also use one of the mentioned apps that adjusts your APNs.

Thank you! When you say 'international sim' do you mean just a sim from another country or do I have to ask for some specific type of sim card? Meaning, if I got to a Vodafone kiosk and get a prepaid sim card would it work?

Yes, I mean a sim from another country.
From what I've read, that's pretty much what you do. You just pay for whichever plan you want then follow those steps in the link. I can't speak from experience so I'm useless there. Depending on the carrier and country, some folks seem to have gotten HSPA others have gotten 2G. I'd love to know what you're results were after your trip either here or in that thread.

For Those looking to use the N5 On AT&T...

Just wanted to give you a heads up on my experience today based on the N5 and AT&T. I walked in and told them what phone i was waiting for and they pretty much set me up in 5 mins with a sim and a plan. They said when i get the phone i should be able to put the sim in and it will activate. He did say that i may have to come in to have the APN fixed if im not seeing the correct speeds. It was a lot easier then i expected, but if your interested in using the N5 with at&t just go in and they can have everything set up for you for the arrival of your N5. As of right now, I'm on their mobile share plan, But i can easily switch to prepaid if i want. I don't don't trust prepaid when it comes to speeds and coverage.

idk about prepaid but hopefully i will just take mine out of my One and throw it in the N5

Just a heads up, you will not have to go in to AT&T to have them make APN changes. You can find all of the different APN settings for AT&T here on XDA on many different threads. That being said, I have the HTC One Google Edition and did not have to change the APN settings at all when I stuck in my sim. I had LTE immediately.
If you do need to change the APN settings they are really easy to do in the settings of the phone, but hopefully the phone will read your sim and know automatically which APN to use.

Where can I find these apn settings? How would I know if I need to apply these settings?

Here is a post that has them: http://forum.xda-developers.com/showthread.php?p=26821716
To get there you go to Settings>More>Mobile networks>Access Point Names > the either select the AT&T PTA from the list or hit the plus button to add the APN settings in this post.
I will take a screen shot in a minute and post it, I have to switch my AT&T Sim card back into my phone to do it (I am using a TMobile sim for a while to see the differences).

Here is a screen shot of the APN selection screen and then the settings held within the PTA APN (which is the LTE APN for AT&T). Just a note this is 4.3 but I am sure it will be very similar on 4.4. Good luck. Mine won't be here until the 7th, after that I will know for sure if it has the pre-programmed APN's.

This phone will not be coming to at&t with a contract correct? Or will it be coming later on, because I know T-mobile said is going to have it in the "coming weeks."

Wow. This sucks doing this from the mobile app! Last try.

I would not expect to see this on AT&T at all. The nexus 4 never made it there, but it was at T-Mobile. That does not mean that it will not work on AT&T though. I have been using nexus phones on AT&T's network since the Nexus One without any problem. You do have to make sure you have an LTE enabled plan to get LTE however. You should be able to do that online.

I too have an HTC One on AT&T. I converted it to a GPe though and receive OTAs. That said, I never had to change APNs either with that device. My N5 should be here before the 7th and I can tell everyone if it's a simple sim swap or changing of APNs

Yeah, I have the mobile share plan w/ 4GB and unlimited talk/txt. So LTE should be enabled.

Sim swap worked fine coming from HTC One.

Thanks for posting the screencaps. Does the APN have to be this ATT PTA? Because I see ATT Phone is a choice and that is the APN I use on my HTC One with Google Play Edition rom flashed, and I have an ATT LTE sim which works fine, I get normal LTE speeds.

I think both work for LTE now. I just checked and seem to come up with the same results with LTE speeds. Something else you might want to check is if MMS works on both APN's. Sometimes this is another area that gets messed up when switching APN's.

I didn't have any problems switching my sim from my S3. Though AT&T still seems to think I have an HTC One X+.

That's because AT&T only has your One X+ IMEI on file with your account

[Q] US GSM Moto G won't work on AT&T

Hi guys,
Just got my Moto G from Amazon. Upgrading from a SG2 skyrocket. Went to AT&T store to get a micro SIM. Before leaving the store I made a test call, worked perfectly. When I got home I wanted to test the HSPA+ speeds. It won't connect to mobile network. Called AT&T and they said the IMEI is not recognized in their system as a phone, and as such, will not be assigned a data plan. I called Motorola and they said since I bought it from Amazon, only Amazon can help me.
So I requested a new unit from Amazon, but then I got thinking...is there a way to fix this without having to return it? I don't want to go back to my SG2 for a week while I wait.
As a secondary note, I had my SG2 look for the Moto G via bluetooth and it was recognized as "XT-######". I thought that was strange that it wasn't called Moto G or something similar.
Any help or ideas?
Thanks,
D.

Have you checked the APN settings?

You need to find out what AT&T's APN settings are (Or whatever carrier you're using) and double check if they match with the one you've chosen on your phone.

wait it's not recognized as a smartphone by AT&T? You may have just answered my question! I was looking everywhere to confirm this. I want to get the G for my mom to use on her line, she has a data block, I don't want to use data. So can you confirm this?

AT&T also has its own prepaid (GoPhone) where you can get unlimited voice/text for $50 no data (wifi only) and aren't required to purchase data. However, it's cheaper to go through an mvno like he said.
I'm on GoPhone myself but I'm debating if it's worth the potential customer service hassles to move to a cheaper MVNO like H20 or Airvoice.

are you sure? Because in my situation, the line already has a Data Block. I read somewhere that as long as you do the data block on the line before switching sims, they can't know it's a smartphone. I may just try it and see if they find out. I'll disable Mobile Data from the phone and make sure it always has WiFi.
