Im going camping next weekend and i get 3/4 bars there.. But it isnt on E or G or anything.. Just emergency calls. Is there anyway i can get around that? Because obviously i am in reach of a tower for signal. It just wont let me use it unless its 911. I dont need internet data or anything like that, just be able to call. Changeable?

Ehh try rebooting your phone or reselect your network.
If you're getting a signal, but you can't do anything but emergency calls, it means that specific network's tower is refusing to let you connect because T-Mobile doesn't have any roaming agreements with them.
And there is no way to get around that...

Unlocking means sim unlocking, or the ability to use any company's sim, provided your phone can connect to their network.
Sent from my SGH-T959 using XDA App
The thing is, if T-Mobile has ABSOLUTELY no signal in an area, they have roaming agreements there, even if it's AT&T.
There must be a T-Mobile tower somewhere near there, so it won't let you connect to the AT&T tower with anything else except emergency calls.
If you really need to be able to call someone, go to Wal-Mart or something and buy the cheapest AT&T prepaid phone, get some prepaid time, unlock your Vibrant, and pop the AT&T SIM in your card. You will get data too, since it'll just use some money off your account for data, and you will get 3G since the Vibrant is AT&T 3G capable.

It will always be slow since its on 2g, nothing you can do.
Why aren't there laws that make it so cell phones are all interchangeable? Something like consumer freedom so you can buy any phone you want and use it on the carrier of your choice.
Use straight talk. Hspa compatible.

Actually, T-Mobile has said they're going to start adopting AT&T's 3G bands with the hope that Apple will let them sell subsidized iPhones. So depending on where you live, you may get 3G on the Atrix. I agree though, more interoperability is needed. This GSM/CDMA split we have is ridiculous.
I'm not using T-Mobile right now, but in a year (when my contract expires) I'm switching to one of their value plans and will unlocking my Atrix to use with them if I'm still happy with it. Given that so far the only spec I see improving on newer phones is the screen resolution, I think it'll still be plenty usable when that happens.

Hey guys,
I'm kind of new to android stuff, so bear with me .
About a week back I bought this Motorola Photon 4g for Sprint off craigslist and used the kddi radii trick to make it work on GSM networks, namely T-Mobile. Right now imeon the hybrid 2.3.5 rom, but even when I was in the stock sprint rom, the carrier name randomly shows up as T-Mobil instead of T-Mobile. Is there any way to fix this other than spoofing the carrier name? Thanks for the help!
From what I know, the name is stored in SIM card, try to replace it with carrier.
Thanks, I'll try that. I'm actually planning on doing that soon anyway . The strange thing is it sometimes shows the full name T-Mobile, I'm still trying to figure that out haha

My phone does this too, I'm not sure why. To me it seems like it says 'T-Mobil' when signal is pretty weak, but i have overall weak signal in my apartment so it could just be me making a bad guess.
same thing
i also have the same thing, but i haven't noticed it till you have mention it.
i guess it belongs to 2G/3G. coz when you are having connected to 2G it tells you T-mobil
while when you are connected to 3G it tells you T-mobile.

You guys must be in the refarm area cause the 3g frequencies are the same as the iPhone's. I'm still waiting on that . Btw I got a new SIM and it hasn't said T-mobil yet so maybe it's just a certain kind of sim that does it?

I tried to do something similar.
I called At&t and told them that I wanted to use a flip phone and gave them the IMEI and everything,I used it for a few days and after I put it in an Atrix 2 I have.After 3 days I got a text saying they added a data plan for $20 to my account lol.
They can read the IMEI of the phone,if you call customer service,they can even tell you what sim is in what phone at that very moment.

I don't think that will work. I had that argument with at&t about not needing the data add-on for my sister-in-law's phone. She wanted the large screen for SMS and doesn't know the internet exists. I put an old 64k sim in the phone, and within the day the phone was cut off. After a call to at&t, they told me I need a data plan with the phone. They detect the type of phone.
Don't bring up the topic of phone cloning - its illegal and banned on xda, as it should be.
So it is "phone cloning"?
didnt know,thanks for the heads up.
I can understand making data mandatory on a subsidized phone but on one bought off contract,it is unfair.

That doesn't make sense. Sprint phones are CDMA not GSM. Sprint network doesn't use a sim card to register. In other words, no sprint phone on at&t network.

To add to this comment. At&t will also know if you are using any smartphone from any network or assume its a smart phone I guess. My wife uses a galaxy s 4g exclusive to t-mobile for about 4 months now. Last week she was hit with the 3 gig addition as well. They dont even know what type of phone it is. All she did was turn on the data to download an sms and bam a day later she got the the email.

I'm using this phone on ST. I had to buy a SIM card & minutes. The SIM card is the TMo card & I bought a SIM cutter to cut it to the right size. I didn't have any trouble actually getting it to work. There might have been some settings to change, but I found all that here.
I only get Edge data, but I use wireless mostly so not a huge deal. The only thing I haven't figured out, despite much searching & playing with settings, is getting MMS to work. Which didn't seem like a huge deal until I realized that anytime someone sends a group text it's an MMS.

"Flashing to Straight Talk" can vary, depending on how you want to go about it... Straight Talk has two types of service, CDMA and GSM, both of which will work on the Rezound to a varying degree.
The CDMA mode is as @mjones73 mentioned, and it required a donor phone to clone the ESN/MEID from to be activated. This will use Verizon service in 3G mode, which is kind of slow (about 600kbps in my area at best) but it will work. The practice of ESN cloning is... umm... questionable though technically possible.
The GSM mode requires a stockish global mode ROM, and a T-Mobile or AT&T SIM card from Straight Talk... Voice and SMS will work out of the box, MMS and data require a little tweaking. There are a few guides out there but @REV3NT3CH is working on a guide to get AT&T 4G on the Rezound... yes, I said 4G! I believe he also has/had 3G working on T-Mobile service with Straight Talk as well. Be patient, those guides will be coming soon, I know he is working on them and they should be ready soon.
I can help anybody flash their phone to straight talk PM me

4G on Verizon (CDMA/LTE) will likely never be possible unless Verizon has a serious change of policy.
4G/LTE may be possible on an StraightTalk AT&T SIM, @REV3NT3CH keeps saying he has it working and will be putting out this step-by-step guide, but so far it seems just like a vaporous apparition.

to answer all the confusion....the htc vigor (rezound) has all the bands to support it...they are just locked by default in the nv....its alot of hex coding and as i do get 4g i also noticed a few errors....like it confusing certain roms to default and do a weird lock and defaults back to cdma only after a few hours of usage on 4g....the reason for its delay on release is kitkat development
As far as gsm goes I didn't even hafta do anything I just popped in my sim card to stock and I could do calls texts yes both sending and receiving (but this is on T-Mobile gsm which should be similar) I haven't found a ROM yet (I'm on PAC man right now) that I can't get everything working on it without too much trouble (I don't have a data plan but I can get MMS to work which works through data)

I'm actually working on a pure gsm kitkat for the rezound....i can also second that right now it doesnt work from straight flash....requires a few build.prop edits and to enter a special menu just to get calling and normal texting to work...data was hit or miss with the 4.4 on the main dev thread...i will also second that using a sim card for straight talk is much less of a hassle than actually flashing the carrier to your rezound and depending on the flash youll never be able to change your rom again without breaking the flash....i use their att version of their sim as tmobile has less likely of a chance to get 4g to ever work on the rezound.....i have gotten it to work with a certain model of their micro sim and sim adapter with a mass multitude of nv edits....
OK been thinking about moving to straight talk with my Rezound. I'm already rooted with custom rom cm10.2. Can I just put in an AT&T straight talk sim card and get 4g coverage? If not are there steps I can do to get 4g working?

no the highest you will get currently is 3g....however i am working on the NV edits (which is required to even get the 3g in the first place) to get full 4g which is only obtainable via the att micro sim and micro sim to normal sim adapter....also you will have to edit the apn settings to get data....same would go if you were to flash it....which just getting a sim is cheaper

No... why would you think that?
Now, if you do something like cloning a MEID/IMEI number, that might fall into a different category, but "flashing" a Rezound to Straight Talk (or most other carrier) involves little more then enabling some of the features and changing a few settings in the phone that are hidden, disabled, or limited by the default carrier.
I think part of the steps to flash the Rezound to get 3g coverage is to have a donor phone and clone it. So you're saying the cloning part would be illegal? What if you own the donor phone and the Rezound outright?

So, you mean move it to Straight Talk CDMA service, not GSM? Different ballgame... ESN/MEID cloning for fraudulent purposes is clearly illegal, doing it yourself for devices you own is a very grey area, the law isn't as cut and dry, if you Google the question of ESN cloning you will find widely varied answers but nothing cut and dry.
I know people who have done it successfully for exactly the purpose and situation you describe and haven't had an issue, but at the same time if Straight Talk/PagePlus or whoever decided to push it, they could say you are performing fraud and possibly violating their terms of service as well since the device ESN is not just a radio identifier, it also is assigned by the manufacturer and registered with a specific device and specific capabilities.
All in all, its your call...no where have I seen this discussion come a black and white answer.
The difference with using SIMs between devices and ESN swapping is clear though and ruled not illegal as the capabilities and service are tied to the SIM and not the not the device itself, as although carriers may require the devices IMEI number for provisioning their services and prevention of fraudulent activities.

As I said, the legality is questionable... Its not black and white.
The Rezound is a Global Phone and has GSM capabilities to an extent... 2G/Edge is possible on all US GSM carriers, 3G/HSPA is possible on AT&T based networks with a compatible ROM. 4G/HSPA+ is marginally possible with a LOT of modding, @REV3NT3CH is kind of the master here on that. 4G/LTE is not possible on any non-VZW carrier.
That being said, the Rezound's GSM radios are not tuned for US carriers, so signal strength and data performance suffer.
