I hate AT&T but I do like the Atrix. If I manage to unlock it, I know I will be able to connect to T-Mobile's edge network, but is there any chance it would be able to connect to T-Mobile's 3G and 4G networks? Before anyone says no out of hand remember an unlocked Vibrant can connect to AT&T's 3G network.
I know this seems like a dumb question but I really do hate AT&T and would rather stick with my Nexus S on T-Mobile than use an Atrix on AT&T. So I'm hoping that the unlikely possibilty exists that I can use the Atrix on T-Mobile's network.

Short answer...NO.
I was afraid that would be the answer, but out of curiosity you said the short answer was no, is there a long answer that is yes?

lol, you don't give up do you? Well it's still no. This phone was not built with AWS bands in mind, which are 1700/2100mhz. In case of the Vibrant, I guess Samsung wanted more world support and offer the 1900mhz which is also supported by AT&T. Either way you take it, it's just not going work.
I suggest you wait for now, your Nexus S will keep you happy until T-Mobile gets some dual core love as well. Just try and be patient, sometimes this pays off in the end ..
Besides, you have more dev support right now, so go flash some ROMs.
Thanks, for taking the time to answer my question with such great detail. I will stick with my Nexus S for sure now. I knew it was a longshot when I posted but a guy can hope.

Haha no problem..good luck, maybe things will change in a few weeks ..anyway all the best!
I can't find any information on flashing samsung vibrant to cricket. I don't care about a full flash, voice and text is fine for my purposes. I don't care about data or android market or any of that.
I have seriously been NON STOP looking for last 2 days with no luck. I checked the cricket forums and I searched the forums here without any luck. I am an amateur I am not going to lie.
But I have a very good general background in technology and, I have already rooted the phone. I was trying to follow a guide I found but honestly I am not 100% sure that even does what I want it to. QPST samsung vibrant but when I do it I cannot simultaneously connect both the phone and run the software. If software is running first my computer won't recognize the phone as a modem and if the phone is connected first the software freezes and I can't even close it with task manager, I have to reboot comp.
Any help at all would be appreciated. I don't even know if this is the right forum for this question and I am sorry if I put it in the wrong place but this is vexing me.
Does cricket even use sim cards? If they are not a GSM carrier, it would make it impossible to use the vibrant on their network/service
Sent from my GT-I9000 using XDA App
Cricket is cdma (sprint, Verizon, us cellular type radio, meaning no sim card) and the vibrant is gsm (meaning it uses a sim card).
The vibrant cannot and will not work with cricket.
Sent from my SGH-T959 using XDA App
Well question solved. Definately not the answer I wanted but that can't be helped.
Are there any nationwide carriers that use GSM available similar in price to cricket? I will be looking into this right after posting this question but I figure I might as well see if anyone knows any decent ones they can recommend. Basically, looking for cheapest possible with nationwide coverage.
I just need talk and text. Preferably no activation fee and no cost for sim but I know I am being overly optimistic with that lol. I also know that this forum isn't the place for that so any help is appreciated but I understand if no one has an idea.

there is the one that wal-mart sells that you could look into
T-mobile note users ....
I'm posting this thread as a request for information today.....let me explain.
Within the past few weeks, many members have reported sim card errors on their tmo devices after root and flash of custom roms.
I personally know about 5 devices within the week that have suffered this failure.....3 of which, have been recovered by downgrading to Gingerbread .....
I'm sure there are many more sim issues we haven't heard about, as they likely haven't posted.
My intent here, is to have as many tmo users as possible, post your flash success or failure, in an attempt to prevent more sim failure issues.
Although I'm an ATT note user, I'm willing to help monitor and collect data here, so future users won't suffer the same fate.
2 of these failed devices were sent for repair, even though they were only days old, and worked perfectly prior to root and flash.
So please, if you are using the T-mobile network........please post your history and results.
Together we will likely find the cause .
And perhaps generate enough attention to the issues, that a fix can be found...
I am not attempting to cause panic, but I feel we need to fix the problem now, before we have dozens of affected units, rather than just a few.
Many thanks in advance ....g

I would mention that many t-mobile subscribers cannot get good data and voice while using the at&t version of the note. With the choice of an at&t and a t-mobile model, you should get the t-mobile model -- you will be happier in the long run.
Happy T-mobile user

I bought an AT&T note off craigslist about a month ago. It was unlocked, before I handed over the cash I put my T-mobile sim in and called a friend he said it sounded great so I bought it. I did a couple of speed tests with it and usually get between 3 and 6 mbps down and a lot slower up. I've had no problems, everything works great including GPS. It's running ICS 4.04 stock AT&T ROM and the baseband is unknown. I don't know who unlocked and set it up but they did a great job as far as I'm concerned. YMMV
off-topic, deleted.
It's all good ranger ....
Any and all info on the T-Mobile network while using the ATT note is welcome ....even the success stories.
I did request both in the OP, as I feel that we need both sides of the user responses to nail this thing down.
I do appreciate your response, and ask you for any assistance you can provide here.
This problem is so odd .....as it's not a brick ....but yet it is ....g
I sold my note to a TMo user...called them today(two days after) and they said it was working amazing....it was rooted and unlocked by an amazingly awesome person though(haha jkjk). The guy never rooted before and said the speed tests were rocking his gfs GS3 in TMo and the clarity of the call was great as well....ait could be a root issue or ROM issue though...
As far as unlocking if the pgones unlocked any way except for calling ATT customer care there is always that risk...plus a three minute phone call and giving someone your imei shouldnt be too much hassle .. So theres that dudes exoeruence from someone that knows what they are doing(kind of)...
The rom I left him on was AOCP CP3 by the collective jsyk

Kflan....
noting the unlock method here.....
I believe you are right.....We have many service unlock options, but only one that is safe....and thats the carrier method...
could this be as simple as users not unlocking the sim prior to root and flash ??? or an improper unlock ???
I'm hoping we can get some users in here to clarify that possibility for us.
Many thanks for bringing that up....g
Thank you Rob....
I appreciate the reply, and I'm glad your device is working as it should...

Users on the T-Mobile network, are losing the ability too see or access the sim card, after rooting and flashing the device with a custom rom.
Generally they are flashing ICS, but we also have some users reporting sim loss while using GB roms as well.
We know a few things that are leading to a possible cause.
The first is the carrier offset (my term for t-mobile users with an ATT device )
The second is the need for carrier unlock for the device to be used at all with t-mobile.
The third is the inability to restore "any " sim activity after the failure....(although a few users have been successful after a complete unroot and downgrade to GB .
Although I haven't yet found a pattern in this ....I have reason to believe we are seeing a carrier related lockout of some kind, as the sim functions fine in other devices, and the device functions normally minus it's ability to detect the sim or any network.
Perhaps a good next step, would be to re-lock the device to the carrier again, after a complete stock restore of the device.
I wish that we had an affected device to try this with, but unfortunately, the affected users are returning the device for repair or replacement.
Not all users will, as they need a working device immediately, and are trying desperately to restore functionality.
That being said, I'm hoping this thread will draw an affected user here, so we can explore more aggressive, and hopefully effective solutions.
I can't ask anyone to risk a device beyond their willingness to try, and with some proactive thoughts from our fantastic user base, we will crack this problem open, and create a fix.
We all know the risks involved in flashing firmware images, but since we are now crossing not only the root/flash barrier, we are adding the carrier change into the mix. And that brings it's own unique set of challenges to the table.
I sincerely appreciate any and all help, in my search to help our note users succeed in fixing the ghost in this machine ....g
I know this is a noob question but I've been reading all these t-mo service/I717 threads cuz I'm thinking of doing this. Does rooting the phone unlock it? I'm on the liquid jb rom.
Sent from my SAMSUNG-SGH-I717 using xda app-developers app
I would like to echo what rangercaptain said earlier in the thread, regarding the fact that the SGH-I717 was never designed to run on the T-Mobile network.
And although we have virtually identical hardware and operational features, clearly something is different enough to cause this issue.
And I "do not " believe it is user error.
In the meantime, I would advise any user thinking about converting the ATT note to use on the T-Mobile network, to think very hard before attempting to do so......at least, until a verified and working solution can be found.
Ultimately, we need a bone stock ATT note, and a t-mobile user brave enough to try the process repeatedly, until the cause is identified, by eliminating one process at a time ...g

Rooting a device simply gives it's user the administrator rights needed to access the protected system and data sections of the device, that are normally reserved to the factory, carrier, and programming engineers of the software.
It does nothing to unlock you from your carrier.
That is done by contacting the carrier, and requesting that service.
It is also possible to be unlocked by a third party, but clearly their are risks involved in doing so while using the ATT note on the t-mobile network.
We are working very hard to correct the current "no sim card present" issue ...g

I have been running the AT&T i717 note on the T-Mo network since Tomin figured out how to get the 4g working, many months ago. I have not had problems with voice quality or sim card issues. I have run the Saurom GB roms, Goldie's Only1, many ICS roms, and now am on the stock T-Mo rom with the Blaze ICS modem.Tried all the modems, and Blaze works best for me. YMMV. I got a new sim from T-Mo to enable wifi calling. My data averages 3-5 megs, upload 1-1.8 megs, but at work I regularly hit 14 meg download. But like everyone, the speed is erratic, but functional for everything I do, including streaming netflix. My speeds were faster and more consistant with the GB roms, but the ICS speeds are plenty fast. I unlocked my phone with cellunlocker.com I think was the service. Nothing but a success story with my AT&T note on T-Mobile. And I get to keep my unlimited, unthrottled $5.99/month grandfathered data plan with 4g (if I used a "known" to T-Mo 4g phone I would have to upgrade. The AT&T note is "unknown" to T-Mo, If I got the T-Mo note it would trigger new data charges). For me, this is the point of the whole excersize. I have been lucky, and the Phoenix area has good coverage for me as far as T-Mo. This has been my experience.

Hello forum-goers! It seems that I am at a crossroad right now. I have been researching switching to T-mobile for the past few months now (I was sold on the Wi-Fi calling feature). I just had a few questions before doing so.
1) Would you guys recommend switching over to T-Mo now or should I wait for the new, new to to switch over (I haven't owned an HTC since the Touch Pro 2 and the One is a pretty sweet device).
2) Does anyone have the insurance/JUMP program, I am pretty clumsy with my phone so I have the insurance with Sprint on my current Samsung Galaxy S II? Would you recommend getting a different type of insurance (like SquareTrade)?
3) Does anyone have any experience using this device in the SF Bay Area? I have heard plenty of good news, but it's mostly in different states.
4) I was flashing ROMs on the Touch Pro 2 (Windows Mobile 6.x) and the E4GT is my first Android phone, what is the learning curve with HTC Android devices?
I don't have much to add but I will say WiFi calling is great to have considering T Mobile's poor building penetration. Sending and receiving text is not an issue but when having an actual phone conversation the other party can't hear you to a few seconds after you said it and the whole conversation sometimes become awkward and confusing deciding who needs to speak next, but its serves its purpose.
As far as the jump program goes its really not a bad idea as long as you get approve for no money down on the original headset or else it really makes jump seems like a bit of a rip off considering you could sell the phone yourself outright and not lose out on the initial deposit you made on the phone.

i just switched from sprint to T-Mobile and havent looked back once. was worth the 180 ETF. I really really wanted to stay with sprint but their service just kept getting worse and worse as they "upgraded" towers. I do have the jump program and i dont see why you want to use a different insurance. its ten bucks for full insurance (sprint was 11 or 12 now i think) plus it allows you to upgrade every 6 months if you wanted to. I have the ONE and i really dont see myself upgrading anytime unless something amazing comes out. The phone really is fantastic.
I'm in NJ so no experience in SF.
Flashing is pretty simple once you do the initial setup which there is self contained programs here in forums that can help simplify that for you. right now im still on stock because i really like the wifi calling and most other roms beyond 4.2.1 dont support it yet. hopefully in the next month the update will be out.
hope this helps a bit.

I ended up pulling the trigger and so far the experience is great.
Stock, out-the-box the device is fantastic, I've never seen something so fluid without some tweaking done to it.
The service in my house is a bit similar to Sprint but WiFi calling negates that. When traveling around I get 4GLTE pretty much every where I go. I have yet to try it in my work environment, but since that is in SF I'm sure I won't have any problems. The only thing is, I signed up for the 2 GB plan. I've never really tracked my data usage since Sprint was unlimited, so I'll just have to wait and see if that is enough.
I am still reading up on how to flash the device, it's a completely different process from my old E4GT. But I am definitely excited to be onto something new and can't wait until I am able to figure out the whole process.
Thank you both for responding to my questions!

No kernel needed. I assume you're going to get the T-mobile One and not keep the S4 right? Then yeah, no kernel needed. Just root, install twrp/cwm and flash any rom you want from the international XDA section. Its what I've done (except I have the att model unlocked to tmobile) and it works great. You can even flash the Google play edition roms too.

I am using the $30/month 100 min/5G-4G Data. Since for prepaid, t-mobile wifi calling still eats minutes......I've swapped to using Groove IP + Google Voice for all my needs. Ported my old Sprint # To Google Voice for $20.00 and have been happy ever since.
Just have to make sure to setup Google Voice app to get all SMS's and call or chat with T-mobile CS to turn off T-Mobile voicemail, as prepaid cannot forward to google voice properly as post paid.
All in all, I'm very happy with T-mobile, and will never, ever miss sprint. Ever.

Coming from the Sprint GS 2 E4GT, flashing seemed so easy, with all the videos from QBKing77, the thorough guides on how to flash the phone, even the super easy one-clicks, flashing was a cake walk. After reading guides on how to flash the HTC One, I thought that I was going to end up bricking my phone.
Luckily I was able to find some videos from Flow Wolf and QBKing77 which basically walks you through the steps on Unlocking the Bootloader, obtaining root, and flashing the recovery. From there, flashing the ROM works just like it does on Samsung devices, with the exception of having to flash the kernel separately.
Last night I flashed TrickDroid 5.6.0 due to many people saying that you are still able to maintain WiFi Calling. So far, I'm loving it!

I've never had the S4 so I cant compare it to that. Its not great, but It will get you through the day fine.
I read a few threads and am confused, so I thought I would just ask. I have a few 4G LTE devices for Verizon and am ready to switch to AT&T. Let's just say that Verizon and I had an argument and it is time to switch. Plus I would be saving over $50 to switch to AT&T with a month to month with a BYOP plan.
I visited the AT&T store today and had them insert a SIM into my S4. I get the error "This SIM card is from an unknown source" in the banner. I get a signal strength and a H for where the data symbol 4GLTE is. Then it drops the signal and refuses to have a data connection. At this time the APN settings were NOT adjusted. This was a straight out of the box S4 rooted on NC5 with Android version 4.4.2. After messing with the S4 for awhile he moved to the S3 and entered the proper APN settings. It pulled data, but only at EDGE speeds or 1X. Also, my last device, a Samsung Galaxy Tab 2, has no way of editing the APN settings. It is NOT rooted and is still on stock firmware.
My questions are these:
1. Can this be done?
2. What do I need to do to the phone(s)/tablet to make it work?
3. Will I be able to get 4G speeds?
I do not want to purchase phones with AT&T today because I just don't have the money. I already have these devices, I just want to swap them over. I am comfortable with flashing using ODIN and even so far as using safe-strap. I have flashed some custom roms, but my phone is a daily grind phone and I really want something that works 90% of the time.
Thanks in advance for any help!

It was an answer to this same question asked by you. This thread is redundant.

That thread just asks if the SIM card would work and if they would need to flash a GSM ROM to their S4. That thread does not answer the questions I asked. I just gave my insight after a visit with the AT&T store. Store techs tend to not know as much as the XDA community. That is why I asked here. So no, it is not a redundant thread. I appreciate your answer, but it isn't what I am looking for. Not a straight up yes or no, this or that.
As for the GSM locks I discussed, it was from an experience I had with a Motorola Droid 2 and using it on a local GSM provider in the USA. So yes, that was pre LTE.

My point, which you apparently missed, is that there is no reason for starting up yet another thread to ask questions that have already been answered. That''s why I said that this is redundant.
OK, let me answer your questions.
1. Can this be done?
Yes, you can install an AT&T SIM, set up the APN, and it will work. What bands you get and what bandwidth you get depends on what bands AT&T are using in your area. You won't likely be able to get LTE speed; most likely just Edge. You can't fix that, as it's a limitation of the phone's radio hardware. Again, some people have made claims that you can flash the AT&T GS4 modem on a Verizon phone and change that, but that's pretty risky as it will likely brick your phone.
2. What do I need to do to the phone(s)/tablet to make it work?
It works, for some level of "work". If you're stock,some people have reported that the firmware requires CDMA for some functions, like SMS. I haven't verified that. I was able to send SMS with my phone and a UK SIM which uses the AT&T network.
3. Will I be able to get 4G speeds?
Not likely. For example, see here http://phandroid.com/2012/12/10/nexus-4-att-lte/ - the common band, LTE Band 4, has limited AT&T coverage.
I haven't gone over the specs of the two phones lately to match them up, so that may be worth looking at again.

Thank you for your answer. I decided to trade the phones into AT&T and get a credit towards a Samsung S4 and a Asus Padphone X. After I read a few more posts over the internet and a few more hours figuring out how LTE works I came across the answer. I did miss what you meant and I apologize. Again, thank you for your answer.
