[Q] Unlocking Rogers, Bell Canada phones for AT&T

From this Wikipedia list...
http://en.wikipedia.org/wiki/Samsung_Galaxy_S_III
...it appears that both Rogers and Bell in Canada are offering a SGH-I747 Samsung GS3 which is listed as the same variant as AT&T. However, they are offering internal 32GB models and AT&T is not, and that's what I want. I'm current using an iPhone 4S 64GB and I want to be able to swap sim cards back and forth between phones. Yes, I know I can get a 64GB microSD card but I want 96Gb on the phone (I don't want to argue this point).
So I have a few questions:
1) If I get a Rogers or Bell phone without contract and manage to unlock it, will it be fully compatable with the AT&T network just by swapping sims cards with the iPhone?
2) Will it work with AT&T LTE as well as 3G / Edge, both cell and data?
3) Does unlocking companies like cellunlocker.net actually WORK? Is this legal?
Thanks in advance for any info anyone can provide.
Tony

The Bell. Rogers, Telus have the same hardware as the AT&t phone other than the sofware, rom and modem is a little different. I have used AT&T phone here in Canada without issues. The only problem, right now for at least the first month, they will not sell you a phone outright, either new contract or as a upgraded only.

Also it is legal to unlock your phone and you can get the sim unlock codes from companies like cellular unlock.

Hola
I will step in here and say you are presently incorrect about not being able to buy this phone outright. I bought it at a local Bell Canada store (32gb) and no regrets yet.
That being said Bell is the only carrier that is allowing this at the moment. But do note buying the phone outright online is not possible which is an obvious limitation if you can't visit a local store.

I have same problem.

I'll take the opportunity to note that Telus also sells the phone outright; you may have to get it directly from them, though.

You can just go buy the phone out right wherever you want I walked into futureshop bought a Rogers s3 then took it to my buddy who works at a cell repair shop and he unlocked it for me. Money is money whoever says it can't be done is flat out lying

Root and Unlock SIM

so this is my first Android phone where unlocking the SIM card is possible. i've been with Verizon and Sprint so long that i never bothered looking up the unlocking abilities/procedures. the only unlocking experience i've had in the past have been with iPhones, where the jailbreaking software has an option to unlock the SIM card as well.
and i didn't know that you have to ride out your 2 year contract before AT&T will unlock your phone. i've tried searching around here, but i couldn't get a good answer. i kept finding threads in regard to a Canadian carrier where you dial a number + an unlock code, but then some ROMS didn't allow the dialing of that number to work (or something like that).
is there a method to unlock the SIM card of the AT&T version without waiting out the 2 year contract?

yes, just keep asking. use online chat. i got both my devices unlocked, one after 25 days of owning and one after 2 days. you do not need to wait out your contact, that only applied to the iPhone.
p.s. the other two larger unlock Sim threads in this board detail all this for you.

ATT will unlock the SGS3 after owning it for 15 days, and as long as your last months bill is paid in full.
call them, or chat them and ask for it :laugh:

thanks for the info. i totally missed the Q&A section somehow.
in related to other threads i found, should i try to unlock the SIM card first before rooting/flashing a custom ROM?

They are mutually exclusive items to do on your phone. One does not affect the other. So to answer your question you can do whichever task you want to have done first.
That said, I like knowing my phone is carrier-lock free asap, so I'd unlock first to get that done.

thank you for the info!
just got off the Web Chat with an agent. all i did was simply ask for an unlock and he gave me the unlock code to use once inserting a non-AT&T SIM card.
i didn't have to provide a reason or anything.
now all i have to do is locate a non-AT&T SIM card to test the unlock, and then i can proceed to rooting this. hopefully the stable AOKP will be part of today's release.

I just dropped by Bestbuy and bought the phone out-right. Un-activated phones and phones without the stock ROM have to use a diff carrier's SIM to activate the unlock screen.
Pick one up on ebay. you can get a T-Mobile micro SIM for like $2. The only thing it's good for is unlocking your phone.
Like the one I bought:
http://www.ebay.com/itm/16086619163...NX:IT&_trksid=p3984.m1497.l2649#ht_500wt_1414

If u got it from best buy you overpaid. Phones are marked up from ATT cost. They are 549.99 with ATT and 700 with BBY.
OP
You can go to cellunlocker.net and put in your IMEI and get a unlock code. Great site. I use them all the time.

Bestbuy does price match. So I got it for $549 plus the $10 in BB rewards.
Why are you telling the OP to pay for it when he doesn't have to?

Guess i'll have to try another time later. Not to mention the guy i chatted with didn't seem too bright. Asked if i could have the SIM Unlock code for my phone, and he said that AT&T sim cards cannot be unlocked.
Told me that it can't be unlocked because it is still contracted to AT&T. Told him i read that people have been getting them unlocked after a couple days of purchasing the device, on contract or not, and he said apparently i was misinformed. haha

lulz;
try a new chat rep, or call them.
like ive said a million times already:
as long as you've had your phone for 15 days or more, and your last months bill is paid in full, you will get an unlock code.
now hook me up with some thanks :silly:

If you're not in a position to call to get the code from AT&T (like me, who got from Ebay and lives in NZ), then cellunlocker.net worked for me in terms of getting a code. Just thought I would mention that for people who see this thread and come to find out about SIM unlocking.

yea, i bought my phone on July 26, so it's been 26 days, and since i just started my contracts with AT&T (new customer), i didn't have a last month's bill to pay. and yet the agent i had unlocked it for me with no questioning.
btw, would i be able to use the LTE SIM card from my old Verizon Galaxy Nexus as a "non-AT&T" SIM card?

If you're waiting on a sim like I was... just install the cm10 nightly for the 21st. It will show the unlock screen upon reboot. I didn't need a dialer code or sim. This bug allowed me to use the code I got from att to successfully unlock my phone.

That is why I listed that site. Cause it works and not everyone has ATT. And sometimes they takes days to get a unlock code. Cellunlocker.net does it within minutes.

After 2-3 months T-Mobile should unlock it for you upon request. Just call them.

So I finally took the time to see if the SIM card from my old Verizon Galaxy Nexus would work.
I turned off my S3, put in the Verizon SIM, and started up. After I unlocked the screen, I was promoted to input unlock code or dismiss. I typed the code in and after a few minutes I was taken to my home screen.
I guess it's safe to say my S3 is now unlocked? If I really want to make sure, I would have to have a working SIM to put in my S3?

[Q] Flash to t-mobile is it possible?

Hi guys,
this may not be the proper forum for this if it is not i apologize.
I have have the cricket galaxy S3 which I payed retail for a few months ago, I am moving to a area where they do not cover, I would like to bring my s3 over to tmobile but im running into a strange issue.
The phone is set to cdma mode in the the engineering menus i can switch it over to gsm and it has the frequencies that tmobile uses but i can not get it to see anyone else's sim card other then crickets, its not an unlock problem, it just says please insert sim with anyone else's, they do something weird they are cdma but have a sim card and the phone will not work without it. I tried installing a rom with the tmobile baseband as an experiment thinking well it may be that, but it didn't work.
I am having a hard time believing there is not a way to get this done so I am turning to the most informed android community I know of for advice, Dose anyone have any thoughts on how to accomplish this?
Please not I am not scared to brick this phone because if I cant get it switched over its a $500.00 paperweight to me anyway it has a cracked glass so I wouldn't be able to sell it anyway.

What model is it? I think cricket is closely related to sprint or verizon. And as far as I know no ones been able to use those models on the tmob or att networks with any success. Just because the option is in the engineering menus does not mean the phone is capable. It was just easier than creating separate apps for every model s3.
Now that T-Mobile has lte in some areas this may have changed a little, but in the past I know cdma phones were not compatible with T-Mobiles gsm network. So there may be a way IF lte is in your market, but I still wouldnt get my hopes up much.

See I looked at that but I couldnt get it to work with my phone, the part that is hanging me up is it refuses to see the gsm sim card, though outwardly they look identical to the lte card that is in my phone im thinking it has to do with the encoding on them.

i have been trying to Odin flash the stock vzw firmware to it, since the hardware is identical, but i cant get past the qualcomm secure boot check

I wouldn't try that again. Way too risky. Odin won't flash an official firmware to a different model device. But if you get it to it would be more likely to brick your phone than not. I know they're practically identical, but any difference in bootloaders could cause it.

well here is the thing, about the unlocked bit I am not sure, but it dose not prompt me for an unlock code, it simply just dose not see any other sim thats put in it, it just says No Sim. I gave up on flashing it with odin, I remembered the rom I was running had options for all major us carriers in it and cricket so i played around with that re-flashing the rom to it try a few things and well that didn't work either.

Well if you don't get it unlocked its probably not going to work with any other carriers network.

That thread may help. It's for gsm phones so I don't know if it'll do you any good, but it's worth a shot!
The Rom itself will have little to do with getting it working on another network. The main items that you probably need to worry about are unlocking and that SIM card.
The sim is tmob right? Does it work fine in other T-Mobile phones?
If you really do think.it's the Rom you may be able to flash a stock based Rom from the T999. Get verification first though as it's probably not like att where we can just flash theirs and it just works! You'd most likely need it ported.

Switching to AT&T with a Oneplus3.

Hey y'all quick question. I am currently on sprint with a Nexus 6. I have been wanting to switch to AT&T and was hoping to buy a OP3 and use that. My question is will I be able to do that? Also how easy is it.

Shouldn't be that difficult.
You can probably go to a store and just ask for a nano sim card and can get it free. Then call or go online and activate the sim with whatever plan you want when the phone arrives.
You can also get just a sim and plan online, but you'll need to give a bogus imie number if you want to do it before your phone arrives. This is probably what I would do as I just don't care to go to the stores. If you don't have an imei handy, you pobably could find one easily in some photos on eBay. Doesnt matter if your imei is same as anothers, and eventually the system will automatically update to the actual phone's imei anyways.

i have been AT&T customer long time and i have the OP3.
they never said anything to me but in the account online. i see the device stated as "unknown" lol.
i am okay with, i dont want them knowing what phone i use anyway.

i work for att, we don't care if u use an unlocked phone, i have a OP3 and work there, u just need a sim, u can see if ur sim from ur nexus 6 will fit, if so no need to go to store, att will automatically know what phone u have

they will know, imei will be updated, i have seen accounts where it shows A0001 which is the OPO, but again att does not care, especially since they don't do upgrades anymore, they don't make money off of devices

Why at&t instead of T-Mobile? Just curious, thought everyone who was doing the switching was going to T-Mobile since it is cheaper with more benefits and great reception (most) places nowadays

Personally - I have an Unlimited plan with at&t that only costs me $10 more than the new unlimited T-Mobile plans, but I have no tether speed throttle, until I hit the general 22gb for all my data. I believe T-Mobile's new plans will throttle all tethering regardless of data used, and will throttle general usage after 26gb.
That being said I do have a Ting sim as well (runs off T-Mobile) and is generally faster than At&t in my area, sometimes over 2x. BUT some key areas that I use my phone and where I mainly use tethering, I don't get T-Mobile coverage.
If I could get T-Mobile coverage where I generally tether and if they didnt throttle all tethering without hitting a cap I would switch.

AT&T unlimited plan doesnt allow you to tether unless you have an unlocked phone tho

I've been on AT&T with a OP3 for 3 months now and it works like a charm. Just sign up and throw the sim card in the phone. 100℅ compatible.

Such as OP3?
But good to know, I wasn't aware, thanks.

give att your N6 imei or you won't get LTE and your phone will be detected as a feature phone :/

Like mentioned earlier, just use your Nexus 6 to get your AT&T service activated, and then swap out the sims.

Is the VZW version unlockable?

(edit)According to user ihatevz in post 7 (https://forum.xda-developers.com/showpost.php?p=72920750&postcount=7), the VZW edition is not unlockable
I see threads regarding TWRP and unlocking etc., but I can't find a straight answer regarding whether or not the bootloader on the VZW edition is capable of being unlocked.

Yeah this is exactly what I want to know. I'm starting to get frustrated about it to the point of going to Best Buy to get one just so I can try it and see.... because apparently no one here has one.

Rule of thumb is no for all Verizon phones.
Some people seems to do it by calling up tech support and trying to fool the other side that they have a non-Verizon device, but I don't think it's worth the effort.

I would agree....if it weren't for the unlocked Nexus 6 I am currently using on Verizon. I understand that it is pretty unlikely for a non-nexus phone to be bootloader unlockable on VZW, but I am in need of a new phone and current deals have a z2 and a Pixel for the same price. I'd prefer this phone over a gen1 Pixel (assuming the VZW z2 is unlockable, ofc), so I'd like to know for sure and someone has one, so someone knows for sure.

I chatted with a VZW rep and they said there is no VZW specific Moto Z2 Play and the one you get from VZW comes straight from Motorola. When pressed for a concrete answer on the unlock-ability of the bootloader, I was given a link to chat with Motorola with the suggestion they'd have more detail. However, that chat didn't go far as the Moto mobile rep said they have no info on the bootloader, then gave a link to the Bootloader Unlock program (on which the z2 is not listed).

Yeah that is why I have a feeling it might be unlockable... if there was a VZW version of the phone, it would be the Droid Z2, not the Moto Z2.
Also the bootloader unlock page says the list is not inclusive of all the models. You can try to unlock it and see what happens.
After this info, I feel more confident about giving this a try, so I am going to order a VZW Z2 Play from Best Buy tonight so I can pick it up tomorrow (I would do it now but I don't have my Best Buy credit card on me for the pickup). I recently learned that there is no restocking fee if I buy a phone and return it in Ohio, so I feel like its worth a try at least as I won't be out anything but time if I don't want to keep it.

Hello everyone. I went all the hassle to buy the verizon phone all the way from china to the usa and guess what? CANT BE UNLOCKED!!! DONT WASTE YOUR FRICKING TIME. So no. I would ask devs next time under the root forum to please indicate what they used to root and unlock the bootloader. Because Verizon cannot. Thanks bye

you guys are all wrong. The phone had the verizon logo on it and it came straight from moto. It sucks that it can't be unlocked. So dont waste your time. I hate the moto service too because they all are from india and think I mean that i want it carrier unlocked. they don't know what boot loader unlocking is.
---------- Post added at 09:57 PM ---------- Previous post was at 09:49 PM ----------
And before all of you ask, yet I bought it from the motorola site and the only option to buy is the verizon version. the gsm one doesn't come out til later. So don't waste your time buying this phone if you want it to be an unlocked bootloader. Just an FYI. And it does come with the verizon logo on it. You can't buy it otherwise. I am pretty pissed off though because I did prior speak to a rep that was a tech that said it could be unlocked even if it was verizon, but what a liar. He must have thought I meant carrier, I am about done with motorola. I have the g5 plus right now and its great but I am tired of the bullsh&t verizon does by not allowing the bootloader to unlock. Like f*ck you verizon.

So they actually said the unlocked version wouldn't have CDMA? Or just their canned line of "the phone has to have CDMA to be part of this network" they rattle off?
Also, wouldn't a phone with VoLTE work if it had VZW LTE bands even without CDMA?

He said it wouldn't come in the cdma form but who knows how he got that...

It's true. The phone only gets LTE. No CDMA roaming. Also texts don't get marked as sent, they do get sent to recipients, but your phone displays not sent.
I literally have tried every firmware, reflashing every modem. I've tried even flashing prl files on it, nothing. It's missing whatever the radio band or whatever it's called, that allows for roaming on verizons network. This means no 3g and no 1x. I often wake up with no bars at all anymore. It takes some time to reconnect. It's pretty bad, not sustainable for a phone.
