...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.

1 yes as long as the Sim is the newer smaller type.
2 yes
3 yes and legal. No warranty void

Sorry, I DID do a search but I could not find anything specifically related to the Canada variants of the Samsung SGS3 running on the AT&T network
Just as a follow-up if I may - How would I then get O/S updates? Will I be able to install updates (like Jelly Bean 4.1 when it comes) from AT&T?
Tony
good question, you will probably get updates through kies regardless, probably end up getting the canadian version (only speaking from experience with the skyrocket) They usually ad an extra letter to the model number to signify carrier, and it will prevent you from flashing an OTA from someone else.
With that said, when an update gets release, it will end up here as well, and you can then choose to flash the AT&T version that way. But thats way down the line.

Thanks. But I'm not quite sure I follow.
What is "kies" and "the skyrocket"? And per your last paragraph, is it possible to flash an AT&T version of the O/S on a Bell / Rogers phone?
BTW - Do you work for Bell Canada? If so, is there any issues with unlocking the phone with a 3rd party unlocker? I don't want to to anything illegal - I just want a 32GB phone that works on an AT&T LTE network.
Thanks,

From what I've seen and heard, I am confident that the big 3's version is fully compatible with AT&T network.
The model is all the same as I747M. Spec are all the same, so.... I am not worried.
In fact, Rogers uses the exact same network technology to AT&T. All the phone works on Rogers will works perfectly on AT&T as well! As long as it's unlocked.
Prior to my purchase of Rogers' SGS3, I was tempted to buy the AT&T version as it's cheaper.....
The point is probably moot since I cannot get either Rogers or Bell to sell me a phone at full price without a plan and ship it to the USA. They won't do this.
So I probably have to wait until one of these phone is offered from a Canadian customer via another source, like eBay. Any suggestions from anyone on how to get a Rogers or Bell phone shipped to the USA?
Jeez...If only AT&T offered a friggin' 32GB phone!! I wonder when those 128GB microSD cards are coming out.
Tony
You can buy the phone outright directly from rogers but yes, you will need a friend's address in Canada to ship it to. Then have that friend ship it to you in the US. Your other option is to come up - many dealers will sell it to you outright.
If you look around xda, the current methods of rooting and unlocking the phone are not so simple or pretty. In addition to that, the risks you'll have to take and extra costs likely isn't worth the extra 16GB.

Kies is the desktop software that samsung uses to backup your device as well as deliver updates
Now can you use this method to flash an AT&T rom on a rogers device. is unknown. in the past with the skyrocket (otherwise known as the Samsung Galaxy S2 LTE) the only difference is the hardcoded model number was I727R while at&t was I727 so flashing which would prevent that.
At the same time, this is xda there are fantastic people that would make a method for you to do that. The key, if you are game to do so is to do a lot of reading, and do nothing without feeling confident in what you are doing.
No I don't work for bell, but if they're here and in need of someone in the Marketing Dept..... However no issues with unlocking on a legal front

I assumed you wanted the free unlocking method. Of course if you're willing to pay for the unlock codes, I stand corrected.
Oh there's a free method? Knew there was for the s1 and s2 but didn't have it for the lte version of the s2.
I would look for the free method usually doesn't involve too many steps.

I'm a new to ATT and was wondering if a lost phone can still be used inside/outside the US when inserted with a SIM card? Or is there something that blocks the phone?
You sound like the guy who "purchased" a GS3 on Craigslist which was sim locked by AT&T when it was reported stolen. Honestly, why would it matter if you're new to AT&T? If your phone is lost or stolen then report it and they'll in turn shut down that SIM. You can report it to Samsung as well who may track stolen devices no matter the SIM entered.
Won't give any other answer as I'm sure it's a violation of the rules to aid criminal like behavior.
Sent from my SGH-I747 using xda app-developers app
Haha. if i had "purchased" such a phone why would i ask? couldnt i just see for myself..?
Why would it matter? cause i just switched from VW, which as you know doesnt use SIMS.. I also just came back from a trip overseas where everyone just switched their SIM cards on the plane.. so being a new ATT customer i was wondering how that thing works.. if phones can be locked despite putting a different SIM locally/internationally.. it's just good honest curiosity. ATT CS did tell me i can put any ineternational local SIM and it'll work as long as its a partner..
You kinda sat yourself up for those kind of comments. You didn't ask in the OP if a phone could be used in/out of country.... U clearly said "lost". This is they word that will probably lead everyone that reads this post to think that 1:its a stolen phone or 2:what the guy above me said. Just making an observation.... If this is not the case maybe you should edit your OP to read differently.
Again.. this is just curiosity.. i don't understand why we can't talk about this.. i asking in general how SIM technology works whether it's active or deactivated.
Since you guys like scenarios VS hypotheticals here's one -- Imagin i lost my phone and bought a new phone under the warranty.. then later found my old phone.. will it still work if i put my SIM in? will i need to report that i found my phone? Those are valid questions that should get valid answers...
SIM cards will work in any phone. You not have to call AT&T to have them activate it. Although I don't know if the new lte SIM cards work in older 3g phones I'd assume they should. And you'd have to return one of the phones because AT&T will block the imei of the one reported lost or stolen. So you generally return the lost/stolen phone.
Edit: Also we should stop treating everyone like criminals because you find the post "suspicious".
Once reported lost or stolen...at&t will block that imei. So no, if you find that lost phone later...it won't work on at&t. Get it sim unlocked and sell it.

here is a set of answers that should help your curiosity, since you are new to GSM/WCDMA-based networks (aka most networks that aren't VZW or sprint):
1. SIM cards can be switched in phones very easily. AT&T's 4G LTE SIMs can still be inserted into previous non-LTE phones (i.e. an old Moto Atrix) and it will work fine as long as the SIM card is valid. Your phone account/line is tied to your SIM card, NOT your phone. this is useful for those who have 'beater' phones for clubbing/debauchery nights.
2. phones from providers such as AT&T are usually SIM-locked, meaning you can only use an AT&T SIM in them. You can use other AT&T SIMs (say, from another account/line) and it will still work fine.
2.a. If your phone is reported stolen to AT&T, they will blacklist the IMEI and it CANNOT be used on AT&T's network anymore, period. So if your phone is stolen, you can have it barred from AT&T. This is why people who buy phones off craigslist often run into issues - the phone is actually stolen. There are no workarounds.
2.b. If you need to use your phone with a different provider's SIM (i.e. another country carrier, or t-mobile) then you need to get it unlocked. this requires a code that you input when you insert a foreign SIM. you can buy this code or get it from AT&T for free, pending a few requirements.
3. Verizon, now that they have an LTE network, uses SIM cards as well now.
Per the insurance rules if you do find the "lost" phone you are supposed to send it to them. I know they black list stolen phones, but from my experience they do not black list lost phones.

I just upgraded an Atrix 2 to an Atrix HD; and after 3 weeks the Atrix HD for a GSIII (fix your software MOTO!). Well between those two phones they switched the SIM card form factor. The Atrix 2 had the ones they've been running since ATT bought Cingular; and the Atrix HD used this one about 2/3 the size called a micro Sim card.
My question is this; can I use my micro SIM in my Inspire 4g I have for a backup?

yes you can. if your slot is snug enough and not a push-slot you don't even need an adapter, just put it in so that the contacts are correctly aligned and it will be fine. did this all through europe when my SGS3 batt died.
I've wondered the same thing. Coming from sprint, I had to verify the ESN wasn't bad if buying used. This one done by calling sprint. I assume its the exact same thing but calling ATT with the imei number to see if its clean?

You will need to be able to hardware mod the phone to accept a GSM sim on top of the hardwired chip.
You'll also need balls of steel.

The sprint note has no accessable sim slot. To "possibly" accomplish this one would need to modify the hardware by adding a sim slot and hack the software.

in layman's terms, you can't. if you remove the back cover from your device there is no sim card slot on the sprint variant to insert a sim. the only current wait to use our phones abroad is to use the sprint international plan.

You could buy an AT&T Note to use with Straight Talk. I have one for sale on eBay right now (Note 1, not 2) that I bought for that same reason, but don't have coverage where I live to make it happen. http://www.ebay.com/itm/290826024805?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
ebay search
note ii sim or search for this one 271090307387
$6.47 swap that plug and play component into place and BAM sim card slot.
either cut a hole in your middle cover OR buy a int middle cover.
also someone is working on a mod solution to keep the 4g AND add a sim card slot
we off course still need to unlock to work on US carriers but maybe its not locked to begin with since they would not have thought of someone swapping parts like this.

very cool. do you know if you can do a similar trick with the ebay sim card holders for the Galaxy S3 (i.e. L710) ? I'm really hoping to buy a sprint GS3, put it on ting, and be able to occasionally take it internationally.
I was about to buy a motorola photon, but the lack of updates is scaring me.

maybe it's just me, but amazing that so many people still believe that phones are compatible with other carriers............if you have Tmobile, AT&T then you're GSM network, Verizon & Sprint are CDMA..............it just bugs me when people ask to get their Sprint phone activated on another carrier (only exception is Cricket). I had someone a couple of days ago who bought a Tmobile version of the Galaxy S3, and wanted to know how to jailbreak it to use on another carrier.
normally you would be absolutely right. but in this specific case and possible with the S3 as well your incorrect.
the Note II and possibly the S3 have full GSM capabilities. Sprint just "corrupted" them on purpose (and should be illegally as well)
with the gizmo from ebay we get a normal sim card slot. now we just need a good hacker/coder to unlock the intentional "block" put in place by sprint to prevent it from seeing US GSM signals from companies other than sprint.
once someone manages to do that we will literally have a phone that could in theory be used on "ANY" US provider and probably any world provider.

I don't know. Someone posted that the LTE SIM card (a chip on the board) is part of this board. so removing it would remove LTE (disable it)
but if your going SIM your going GSM so can't use sprint LTE anyway. so its not a "huge" deal.

Another option seems to be sign up with Verizon buying real cheap 10$ phone and change the sim card.

You what mate?
AT&T and Tmobile are GSM networks, mostly compatible.
You can use any AT&T phone (even locked) on AT&T or one of their MVNOs, basically resellers of their network. See here:
http://en.wikipedia.org/wiki/List_of_United_States_mobile_virtual_network_operators
If you unlock it, you can also use it on Tmobile, or any of their MVNOs. But Tmobile HSPA+/LTE data networks may or may not match up too well with your AT&T phone, depends on the phone.
Sprint/Verizon use CDMA, a fundamentally incompatible technology from GSM, so it is a no-go.
okay , i switched to tmovile and got an LG G FLEX. Turns out this phone is piece of ****, dropped 2 feet with the rubber case and screen cracked. Now I am going to use the ATT NOTE II with tmobile. Once I transferred the sim card out of that ****ty LG G FLEX's SIM onto NOTE II, it says network locked SIM card. What do I do? should I bring to tmobile and attempt to have unlock the sim card? Or Bring to ATT? Thanks.,

When I moved our Note II to T-mobile, I got an unlock code from one of the websites. Then I took it to T-Mobile and used that unlock code at the store. Lot's of sites that will send you and unlock code and directions to unlock. You can search this forum for "SIM Unlock" and you'll find plenty of threads.
Did you get the T-Mobile "JUMP" for the Flex? If so, then you can have it replaced, otherwise you're SOL.
So - this is my 1st Dual-SIM phone, and I'm very happy to get away from having to carry 2 different phones (personal on T-Mobile; work on AT&T - in the USA). I thought that everything had been working correctly - until I was away from my Wi-Fi signal. If I have SIM1 selected for data (T-Mobile), everything is fine. If I select SIM2 - I get nothing. It always shows 3G for AT&T even though I'm in a very strong 4G area for AT&T.
I've been through the Access Point Names settings for AT&T and they matched what I found on AT&T's web site. I even duplicated them with a new name to make sure that they were correct - still nothing. I've played around with which slot the SIM card was in as well as only installing one at a time (just AT&T in SIM1, just AT&T in SIM2, etc.) rebooting the phone each time - still no luck.
Hoping for an assist or "things to try" from the community as I don't expect much help from AT&T on an unlocked phones. Any help is very much appreciated!
Thanks!

Welcome to the DS family. Does SIM card manager show 4G/3G/2G enabled for both SIM's? On my older Note 8 4G wasn't supported simultaneously so you had to manually switch the 2nd SIM to 4G but on my Note 10+ this limitation doesn't exist but still worth checking.

4G/3G/2G is selected for both SIM's, but still only shows 3G for the AT&T SIM.

That would've been too easy. Do you observe the same behavior if you swap the SIM card positions? Also what if you put in just the AT&T SIM by itself (i.e. does it ever get 4G in either slot)?

I've tried both slots with just the AT&T SIM - never get data and never anything but 3G. Strange thing is calls and texts go through...
Hmm, that sounds like it's missing an LTE band it needs to get 4G with AT&T. I don't have an AT&T SIM hand to test with but for the non-US Samsung phones don't have full support for the frequency bands US carriers use (I'm assuming you have an intl phone so correct if wrong.).
I have the dual SIM and get LTE on ATT. I reckon you need to contact ATT and tell them you are using a note 10+ and need LTE enabled.

Spent 2 hours on the phone with them last night. They had me set up the Access Point names over & over - no luck. They suggested I buy an AT&T branded phone. Big help...
I once came from another device to another device and had the wrong kind of sim for 4G/LTE. Or maybe the sim is damaged, or it's just registered wrong.
So: try Hard reset the device AND get a replacement sim card from ATT (can get them at the store and don't let them sucker you into paying for it). Perhaps that will do it.
Came across the post below - I do have an old AT&T SIM card (6 or 7 years?). Looks like an Android 9 update at some point caused issues with older AT&T SIM cards. I'm heading out to get a new SIM from AT&T tonight... Thanks for the attempts at helping - I'll update tonight and let you know how it goes. May be in for a fight - it's a corporate phone and I'm not authorized on the account...

So - I was able to get it working. I had been using the same SIM card for 6+ years. However, getting a new one didn't fix the issue.
They said that the IMEI number wasn't coming up as a valid number. I had a One Plus 7 Pro laying around, so I had them register the new SIM card to that phone, and it magically started working (the old Sim didn't work in it, either). After getting that working, I just moved the SIM to the Note 10+, and haven't had any issues, since.

I don't use Samsung Pay, but it was there lurking on the side (I disabled it). I use the Samsung Shop app for rewards - it works just fine.

Thanks what was the exact model number of your phone?
I guess it's time for me to sell my TMobile one and get the international one. I use the Samsung Pay / Cashback and Shop Samsung app from their set

Did you notice any signal degradation on T-Mobile with maybe lack of bands?
Lastly where did you buy yours from? If it was eBay what was the seller name?
Thanks
