Going to buy an unlocked GNex to use on AT&T, anything I need to do?

Hey guys, im gonna buy an unlocked GSM GNex soon for use on AT&T and was just wondering if I had to flash anything (radio, ect) or can I just plug in my sim card and get right to it?
Thanks!

I too did the same and it works just fine. I am curious about my plan though. I still have the unlimited Data plan. I had the Captivate and got an iPhone 4 in trade for something. I switched to it until the Nexus came out.
I had to call AT&T and have them change my plan so that the iPhone would get data. When I got my Nexus I just put the sim in an adapter and have service with Data. Interestingly my phone shows up as a Captivate again at the AT&T website. Anyone familiar with AT&T plans to tell me what plan I should be on now?

one x on go phone plan?

im in a werid situation. the only phone i want is the htc one x. my plan expires the 26th of this month and i dont know what to do the phone comes out may 6th. heres the deal my dad is making me pay my line by myself so he will give the original family plan line to my little brother. so with his upgrade i intend to buy the one x and use the 50$ unlimited plan from their go phone options
will everything work ? the guy told me data wont work on 4g phones. and will a go phone sim even work on a smart phone ? i really want all this to work out because i need a nice screen and camera but do not want a contract. what other options should i look at because even atnt contracts minimum is close to 80 bucks !

are you talking about using an international one x? i decided on a prepaid plan and it works - but i bought an at&t branded micro-sim card from amazon. others are cutting down at&t sim cards. some are transferring micro-sims from unlocked iphones. there are people posting on the boards that the $50/month plan works for them - you just have to be careful about not drawing attention to yourself by your data usage. i am a minimal user so i went for the $2/day when used only plan (i am on personal wi-fi most of the time) and bought a data package.
you should also be aware that carriers like straight talk and net10 are offering $45-$50/month unlimited plans with purchase of their micro-sim cards. you can find out which network they run off in your area - they all use the towers of the larger phone companies.
check out some of the threads in the general forum as well as this one mentioning at&t. may help you. just be aware that having an international htc could mean no access to certain apps. it seems, for example, that google wallet will install but not open (at this time) on an unrooted international one x. could be a function of at&t, but i think it's google. found a way around that for google voice, but not for wallet. don't know if google wallet will install and open on an unrooted phone.

thanks for all the info. i was able to see h20 works in my area. im not buying the international version this is straight up the may 6th atnt released version. thats why im curious how am i going to keep the same number yet somehow use call sms and minimal data. i too am on wifi a lot but i def need 3g for work and gps. im just worried about getting a micro sim card and im hearing a lot of people getting cut off data on atnt once they found out their using a smart phone
also sucks to be buying an lte phone and no lte available lol
would this work ? what kind of speeds are on it

there are a couple of people on these boards who are longtime at&t users and know far more about the ins and outs. you might try searching them out in the at&t-related threads in the one lx forum, since you are planning to buy, i gather, an at&t phone. better to know ahead of time what you can and can't do. it may still be worth your while to check out straight talk and net10, however, since the last i looked they were advertising programs for at&t gsm phones that claim to be unlimited for $50/month. no lte, obviously, but also possibly no hassle over a separate data package, though they are making it clear they will pull your account if you go over their "unlimited" limit.

alright i searched around a lot and straight talk does use atnt towers so that may be my best bet i just need someone to help me confirm that if i buy the atnt one x should i let them install a sim card in it ? will it even matter? as soon as i get home i would take that phone out and put in my prepaid one. does atnt prepaid not let u use data anymore for 4g phones? lol so confusing

check out howard forums re at&t prepaid and also straight talk. i got into at&t recently. apparently there have been some policy changes that i wouldn't have noticed since i am not a long time user. one of them applies to smartphone data usage limitations - as in, you have to buy a data package if on one. there are a couple of people on these boards claiming they are using data without a data package on their smartphones and it's a matter of not triggering usage limitations. i have no way of knowing and it's confusing to me, too, so i'm just sticking with what i have till i run into a wall, then i may jump to net10 or straight talk also.

Use with dumbphone plan on AT&T?

I used to have the international version of the GSII, and I was able to give the IMEI to AT&T, and tell them that it was a dumb phone. This allowed me to use the unlimited $15 data plan.
My understanding is that this is because they don't have the IMEI in their system since it's an international phone. If I were to buy the Galaxy Nexus from Google, would I be able to do the same thing? Or would I have to import one from Europe/Asia? Not sure how the IMEI thing works

Guess I'll try it anyway

Did it work? Anyone know? Looking to do the same thing. Currently have a nexus one on the dumbphone plan, looking to go to a galaxy nexus.

If you already have the plan, go ahead and try it.

I would like to know if this worked as well. I have a photon which is an American phone but is also a world phone and by default is locked to international GSM. Im about to use the domestic hack for the radio to use this as a go phone. Att shouldn't have the imei in their system because its not supposed to work for att lol.

The general consensus is that only the international gnex's can use the unlimited att data plan. Some how att was able to recognize some gnex's bought from the play store (USA) and flag them as smartphones. There is another thread floating around either here or in the sgs3 forum that showed this.

What's this I keep hearing about people buying phones from the play store??? I've seen this all over. Also would this even apply to the photon? The photon is an American phone that can run on GSM but is locked out of domestic and will most likely never get unlocked for domestic GSM use. So would att log the imei as a smartphone?
Edit: we can use a hybrid radio made custom by a dev to allow domestic GSM but the radio used is from a Japanese phone

Using AT&T Nano Sim LTE question

I currently have a iPhone 5 from AT&T and am looking at getting a S3 off eBay. Now my question is if I put the AT&T sim in the AT&T S3 will I get LTE? Reason i'm asking is I see that AT&T has 2 separate LTE plans, one for the iPhone and one for everything else. I already have an adapter for the nano sim.

Its just because iphones have an additional APN they work with. If you're provisioned for an iPhone plan you will be good with any other smartphone(apart from blackberries)
all you have to do at this point is put your sim in that micro adapter and you're good to go.

Wrong! You have to add the imei and the correct data plan on your account or you won't be able to access data. I work for a retailer and have people constantly coming in after swapping phones and their data is not working. It don't cost anything for a rep to add the correct soc codes and imei to your account. Just stop by the closest store to you and ask them to do it. It just takes a couple mins and saves people from getting pissed at at&t thinking there is problem.

Wrong! Don't be rude to me when store reps like you call into me for tech help. IMEI on the account does not effect ANYTHING. If a customer needed me to activate a phone of theirs, had the SIM but couldn't access the imei, I would dummy it. As in, put 1111111111111119 in the system. And believe it or not... but it would work.
I've had customers switch from iPhone to Motorola RAZR, for example, no problem. IN FACT my girlfriend has a Blackberry data plan. She HAD an iPhone while using that plan. THEN she sold her iPhone and bought an HTC ONE X. Wouldn't you know, that worked too! I had tech disable the RIM feature on the account and add XIP provisioning (regular data provisioning)
Edit: disclaimer: unless in the US they have crazy provisioning on their plans to completely restrict a regular smartphone from not using an iPhone plan, then I apologize.

[Q] I Don't Want To Pay for a DATA PLAN!

So check this out.... I am an AT&T user and back when the HTC HD2 came out for T-Mobile I bought it from a friend when they signed up for a new contract. Got an unlock code from Ebay and have been using it for the past 2 years without having to have a data plan, never got added automatically to my plan like i have heard happen to others? And I'm wondering why? Is it possibly cuz its a T-Mobile phone? Or is it cuz I still have an old "Cingular" SIM card? I am curious about this because right now, Wally World has a special sale on the phone at $249, plus a $100 gift card, which will bring the phone down to $150 basically, so a pretty damn good deal for a phone just out on the market. And I'm plan on getting it this week, I was wondering if any of you would be able to tell me if at some point if i was able to get a T-Mobile version of the Samsung Note 2 if i could slip my SIM card into it and then be able to cancel my DATA plan, if i told them i went back to a Motorola Razr or something, which worked when i got my HD2? Or will AT&T be able to see that i have a smartphone? Is it the newer smaller SIM card, that will tell AT&T that I have a smartphone, or will the phone it self be what sends info to the servers or whatever that tells AT&T I have a smartphone? Or do you think this method of getting a T-Mobile phone and using an AT&T SIM card will work and I won't get stuck with a DATA plan? Everywhere I go has Wi-Fi so I have no need for the Data plan it will be going to waste.

The newer phones, including this one, use a micro-SIM.

I think it is because you have a phone that is not sold by AT&T that they can't tell what it is, so you would probably be forced to get a data plan if you get the AT&T Note II. I would think that regardless of the sim card you have it would still report your phone model to the network, but I really don't know anything about that, so hopefully others can chime in.
I have been using an unlocked Xperia Pro on AT&T and they don't seem to have a clue what it is or even that it is a smartphone, so I could probably do whatever I want with the data plan.
If you got the international version of the Note perhaps you would not have to have a data plan.

I'm wondering if it has something to do with the IMEI? If it isn't listed in there network or something? Maybe I will be alright? I don't know... But back when I got the Tmobile HD2 I went from a Motorola Razr to the HD2 just fine and wasn't automatically enrolled into a data plan, like some others people on at&t were that got the same phone. I don't know how I wasn't, but I'm happy I wasn't and was hoping to find out how to avoid it again. Everywhere I go has Wi-Fi, I don't need to throw away, $15 to $30 extra a month when I'm not even going to use the Data network very often. I have been going just fine with my HD2 with no data plan, just using Wi-Fi.

Right, I know I'll have to get a new SIM card and that is what kinda worries me, I don't know anything about the SIM cards. I was just curious if my older "Cingular" SIM card is what was helping keep me stay under the radar of them not knowing I have a smartphone, or if its because, the HD2 phone I have is from Tmobile and not in their system, so it can't recognize it? I went from a Razr to the HD2 and it still shows as a Razr in my account. An when I get the Note 2 phone, hopefully from Tmobile sometime, I was hoping I can still get away with not having to add a Data plan if i can find out how to avoid it...

Its all in the IMIE ... I was using a Galaxy Nexus overseas on a dumb phone plan because they didnt have the IMIE in system they couldnt tell it was a smartphone but they have cracked down on it now. Only phone that seem to be making it through the loop hole is overseas ones that are not very popular. If you switch to the AT&T version you will 100% be put on data plan if you choose a note 2 from say Rogers there is a slight chance you could sneak under the radar and not need it but for how long no one really knows.

I've seen people come in with T-Mobile phones or international phones and they don't register as a smartphone with the IMEI. So no data is required with unlocked phones.

Do you work at an AT&T store or something? Just curious, cuz it kinda sounds like it from the way you worded that reply. I've read on other threads that AT&T does checks or sweeps every now and then, that might detect a smartphone? Have you heard about that before, not sure what they meant by that?
