A buddy of mine has a Droid 2 Global as a personal phone and an AT&T crackberry from his employer. With a turbo sim or other unlock method is it possible to be on both networks at the same time with the D2G? He wants to be able to receive voice calls from either network and use Verizon for his data. He's just sick of having to carry around 2 devices when oncall.
I've already got him rooted and on Fission, but I'm not very familiar with this device as I'm an Epic user.
No, you can only use CDMA or GSM, not both at the same time.

And even if you could, Verizon locked out all US GSM carriers.
Hi there, I really like DROID RAZR MAXX HD, but I am not a Verizon user. I am sure it can be used globally outside USA. I am just wondering if I buy a unlocked DROID RAZR MAXX HD from Motorola or Verizon, is it gonna work on Straight Talk's 3G network? Someone told me yes but there was someone told me no. I am really confused now.
Thanks if you can help me. I really like this phone!
Straight Talk uses ATT‘s network, I guess if it work on ATT, then it should also work on Straight Talk
I believe unlocked Verizon phones still have domestic GSM locked being the phones software is the exact same minus the bootloader is in locked
Being that the bootloader is unlocked they is prob a fairly easy was to fix that..but out the box prob not
Can someone that has a dev x926 please try a att sim card???

Straight talk also has phones that use CDMA
Won't work. Straight Talk is basically ATT, and an ATT SIM does not work, the GSM radios in the phone are for international use only and will not transmit over ATT/TMobile towers. It might work for about 30 seconds until the phone figures out its on GSM in the US, then it'll flip to emergency calls only.
Even an international SIM card won't work because they ultimately will connect over ATT/TMobile while in the US. So, to sum it up, you can buy the VZW HD/Maxx HD and it is unlocked -- but it really only helps you when you're abroad.

Did you change the service mode from GLOBAL to GSM/UMTS only on it? In global mode the CDMA radio is active which is why it's seeing Reliance and trying to prefer it.
Got a Code from Unlocker From Motorola, But That Code is Giving Unsucessfull Message Which means it cannot be unlocked
How are you even getting to an unlock screen where a PIN is requested? The American (Verizon) version I have does not ask for any code regardless of the SIM that I put in....
Can verizon's version of DROID RAZR MAXX HD be unlocked and used in India?

Just GSM unlock your phone and use a AT&T straight talk card. You would have to change your APN setting but thats pretty much it.

I a new to all of this, is that hard to do? And, where do I go to unlock the GSM?
http://forum.xda-developers.com/showthread.php?t=2166542
There are other methods as well, using different software tools, but the basic requirement is to make the NV edit in the radio to allow US GSM carriers.
I've read that the update will bring new global roaming capability, so has anyone tried to stick a GSM SIM into the phone yet? Does the new JB update bring unlocked 3G GSM?
No, it does not. I updated to 4.1.1 bone stock and got it to register on T-Mobile's network, but there is no way to change APN's, so data and text/mm do not work.
Now, before the update you could root and get a program to add in the APN of whichever network you wanted... folks (including myself) have had it on AT&T and T-Mobile's GSM networks, albeit without WCDMA ("3g"). Check out http://forum.xda-developers.com/showthread.php?t=1895684 for progress on getting WCDMA working on the 1900 band. The phone works on the 2100 band out of the box, but no US carrier uses that for WCDMA.
Okay, that said, post-update, I am sure the same APN tricks that worked pre-update, will work now, but sadly one has to be rooted to do that. Attached are two screenshots from while I was farking about with it.
Why not root, then? No disadvantages that I can see

I like how they're legally supposed to have it unlocked but still, here we are a half a year later.

To be honest, I'm amazed that VZW is allowing you to use another carrier's GSM SIM at all without some sort of unlock code (since this is the case with most phones sold in this country).
I assumed that their "Global Roaming" capability meant that you can take your SGS3 with the VZW SIM to countries (e.g. everywhere other than the USA) that only have GSM (WCDMA/HSDPA) and pay Verizon's extortion (roaming) fees. Maybe the lack of unlock is due to the fact that the phone's primary radios are LTE and CDMA?
If someone can confirm that rooting the phone will allow you to change the APNs it would be greatly appreciated. My family is vacationing in Costa Rica this winter. I've already acquired a couple of unlocked AT&T phones that we plan to use with local prepaid SIM cards, but it'd be nice to be able to have the option of using my I535 there as well.
Thanks!

Yep, had it on T-Mobile and AT&T (GSM only) here in the states, and worked great on O2 (with HSPA+ YAY) in Germany. Page 6 for my screenshots of Domestic carriers, page 9 for screenshot of me on O2.

Its not as cut and dry as that. If you have to root the phone to move carriers technically you are in the wrong. If that is what you mean by unlocked.

Actually you are wrong. He is referring to the FCC ruling. And we should not need to root to be unlocked. I think that is the point he was trying to make.
Does the inability to change APN affect only the domestic US carriers or is it true for any country's Sim card you put in for gsm use. (Verizon global phones have in the past operated where domestic sims don't work but international ones do)

I recently updated to the leaked K3 while traveling on business in the Philippines. While voice and text work, there is no way to add any new APN settings in both GSM/UMTS and Global modes. When clicking on Menu in the APN settings, the only option is to restore to default.
Note that while voice and text do work, there is a notification i the notification menu stating "Non-Verizon SIM: Sorry, this SIM card is not supported. Please..."
I believe that the frequency the carrier runs on is GSM900. Hope that helps clarify things. I spent way too much time trying to get 3G to work over here to no success.
Has anyone just tried using Verizon's Global Data Plan ($25 for 100 MB)? Is the S3 somehow not compatible with that plan?
I'm looking at getting the VZW S3 but I've heard all kinds of things about getting the Verizon S3 to work globally pre/post JB update. I know the local sim rates are much cheaper, but for an occasional traveler this is supposed to be the easy solution.
Just curious if there is a way to get the t-mobile feature of wifi calling on phones which are not running the stock t-mobile rom? I have a phone in canada that uses a US sim for when we send drivers to the states for deliveries (transportation company) but the phone is from canada.
Can this be achieved? Is there maybe a successful app that can do this?

Nope. Many have tried, all have failed. It was possible until T-mobile changed the APK when ICS was released.
How did the APK affect everything? Did they add some special code that makes it not function properly?
So would changing the rom from lets AT&T to T-mobile or from Rogers to T-mobile, would the feature be successfully unlocked?

I don't know the specifics, but it is built into the framework of the ROM. Yes, changing the ROM on another network's device to a T-mobile ROM will allow you to use the Wi-Fi calling feature.
Figured as much.
Thanks for the responses.
The first requisite is that you're using a T-Mobile SIM, because the SIM has an internal authentication method that interfaces with the internal Wifi Calling app. You can't use any other carrier's ROM/Wifi Calling (e.g. Rogers' Wifi Calling) with a T-Mobile SIM, even if both carriers use Wifi Calling.
The second requisite is that the carrier actually supports Wifi Calling. It requires specific Kineto servers on their end.
Thirdly, you can flash a T-Mobile ROM on, say an AT&T phone (I've done this with an AT&T S4) if the phone can handle it, and that will "enable" (because it'll technically become a T-Mobile phone) Wifi Calling.
Fourthly, Wifi Calling is more than just an APK. Previously, it used UMA; that meant that the phone sent normal GSM signal over Wifi instead of through it's cellular radio. Now it uses a proprietary SIP (completely internet-based) protocol that nobody has been able to port to other ROMs. It's extremely embedded into the software framework of the phone.
So pretty much if you want to be able to use T-Mobile Wifi Calling, you need a T-Mobile phone or a T-Mobile ROM. The good news is that T-Mobile phones are fully compatible with all carriers in the US & Canada. They have all the required frequencies for every carrier. I have family up in Canada, so I'm familiar with all the Canadian carriers and what bands they operate on. Or like I said, you can flash your phones (depending on the phone, if T-Mobile also has it) with a T-Mobile ROM.
By the way, calling to Canada would still cost you with a normal T-Mobile plan. It's considered long-distance from a US perspective. There are apps you can use to make phone calls to land lines over Wifi, like Skype (if you pay). You could also use free apps that allow you to make calls to other people using the app (like Viber, which also does free messaging similar to Whatsapp and has a desktop app).
You would also need the right SIM card. Not all T-Mobile SIM cards support Wi-Fi calling.

Considering he said his sim was from the US, I think it is safe to assume that it is not a Canadian sim, and most likely T-mobile.
Uggg, this XDA app is terrible, I can't even edit posts. Anyways, how do I know what SIM card this person has? They didn't say, but even if we assume it's T-Mobile that's no guarantee it will work.

Glad to know that there are a few people here that know about the canadian phones. I just found the t-mobile rom so I am going to try and flash it via odin on my canadian phone.
And for the record so it doesn't confuse other XDA members, its a T-mobile sim and one of their more recent micro sims.
Don't ODIN another model's ROM. Stock ROM files include a modem. If you flash another model's modem, you will lose your IMEI. You need to root the phone and install a custom recovery so you can flash the ROM without the modem.
Pretty much all of their SIMs from the last two years will work. So that's not an issue. Like I said though, Wifi Calling simulates being you in the US. For example, I visit my grandparents in Ottawa. I use their Wifi to make Wifi Calls on my Galaxy Note 3. The calls are made as if I'm in the US. Meaning if I used Wifi Calling to call one of my friends who lives in the US, it counts as a domestic call. But if I call my grandparents' house phone, it'll be long distance, the same as if I were in the US making the call to Canada.
If you're trying to save money on calls, this won't work since you'll still be calling Canada long distance.

Glad I caught this. I didn't think this would actually have such a possible outcome.
Where can I get the t-mobile rom only then? sammobile doesn't seem to bring up the rom when i type in the model number of the phone.

Which phone is it?
It's probably easier to go with a custom T-Mobile ROM from here on XDA since you won't be taking official updates anyway.
N900w8 - telus carrier.
EDIT: judging by the second statement, the custom roms aren't exactly AOSP based if one would still want to acquire such a feature.

The Canadian Note 3 is actually equivalent to the T-Mobile Note 3 (same frequencies). You can flash a T-Mobile Note 3 custom ROM from here (just don't flash any modems). Get one that is Touchwiz based. NB4-based ROMs (Android 4.4.2) are the latest. Vision NX3 is one that I use and is a minimally-tweaked stock based ROM (it includes some T-Mobile bloat, but that can be removed with root apps like Titanium Backup).
Would it be possible to flash a stock T-Mobile rom to at&t lg g4 I can skip the modem flash, I know that's a bad idea.
Hi,
Just bought today the verizon variant of the galaxy s6, and I need help with a couple of questions:
I'm moving to Europe in the near future, would I still be able to use the phone?
From who do I get software updates? Will I get updates from verizon even if I'm abroad?
Would it be able to flash international firmware on this phone in the future? Are the models fundamentally different from each other or are they just handicapped by firmware?
Thanks in advance

Yes it works internationally, I'm using it on GSM right now and plan to use it in Egypt over the summer. You will get updates but I think verizon needs a verizon sim to check for updates but when one releases you can always check through a computer if you need to. As far as I know verizon one is the bay because it supports CDMA radios and GSM radios and comes pre unlocked while other versions like tmobile only support gsm. That's the only hardware difference, the rest is all software.
Also be careful with your phone! Nor sure where in Europe yuppie going but some classes visited Spain recently and lots of them we're pickpocketed and had something stopen.

Hi,
Didn't u have the same issue with texting?
I bought my s6 from verizon on a trip in the USA, but I live in UK and using 3 network. The only issue is the texting. I spent lot of time to figure out what is the real problem, and it seems like it is sort of prefix problem. If I receive message from someone with new number with +4407 (obviously all of them start) and I reply, message is not going to be sent and I always get a message: " Your text to speech message to 0114407..... has been rejected by recipient phone." I never use text speech btw, and it definitely prefix problem because if I send to 07... only they receive it. I changed all my contacts to 07... but still after that I couldn't reply to messages for a long time just only with the Handcent next sms app. But If I receive a new message from a new number I'll get with +447.. and I need to save it and change the number to 07.. otherwise it will never work. I found some people had the same issue in the past, but there was no final solutions: http://forum.xda-developers.com/showthread.php?t=2106370
