I would like to know this as well.
I heard that the Thunderbolt can't do this so I doubt it.
Moved to general as not android development.

The Thunderbolt isn't a world phone, which is why you can't do it on the Thunderbolt.
Have you tried putting in a different SIM card? I haven't tried that, but if you switch to a GSM carrier, there should be a way to turn off CDMA roaming and enable the GSM options, that appear to be grey-ed out for some reason...
Called Verizon Global Support a few days ago and had them give me the SIM unlock code. Once unlocked I was able to insert a T-Mobile SIM card. I went to Settings>Call>Preferred Network and changed to GSM. I was able to make/receive phone calls on the T-Mobile network as well as connect to the Edge data service. I did however have to add the APN setting for T-Moble (epc.tmobile.com) to get Edge service.
I got the I2 a week ago and 2 times I have unlocked the screen to see a dialog box saying I have lost my data connection and prompted me to choose between CDMA and GSM modes. I haven't tried to switch modes, but it worries me that I am losing the data connection.

Even though the data is just Edge, it works on T-Mobile in the U.S.? Interesting. The only other global Android devices on Verizon so far - the Droid Pro and the Droid 2 Global - have T-Mobile and AT&T bands completely locked out. I wonder if it would work on AT&T as well.
Yah it works quite well you have to manually change the apns in the GSM settings. I did find the switch to change calling modes between GSM and cdma it's under settings ->call settings

If it's not switching over on its own, try the test mode - *#*#4636#*#* and then in there you can choose GSM (PRL) or WCDMA preferred, both of which switch you onto GSM or 3G GSM respectively.
Did anybory try?

Did anybory try this? Is 3G works on Inc2?
By the way:
Inc2 supports:
CDMA 800/1900MHz +
UMTS/HSPA 900/2100MHz +
GSM/GPRS/EDGE 850/900/1800/1900MHz
And some info from t-mobile forum:
Mobile USA's frequency is the AWS 1700/2100 band also known as UMTS1700. Europe's band is 900/2100, also known as UMTS2100. The phone must be able to connect to uplink and downlink for it to be compatible on a network. Since his Nokia was UMTS2100 it could not connect to T-Mobile's 1700mhz uplink frequency.
3g works in the uk. No idea about T-Mobile

How they gave your unlock code - did you by phone by _retail price_?
Does anyone know if it would be possible to only have T-Mobile US SIM handle only the calls & texts part, and Verizon data with the Pre-Paid $30. unlimited data?

You call Verizon. They verify that you've been a customer in good standing for 6 months or more, and they give you the unlock code. No charge. You can't unlock more than one phone per account per some period (13 months, or something like that). It doesn't matter if you have a contract term, etc. (you don't need to pay full retail for the phone).
Once you're unlocked, you can use a SIM from whatever carrier you choose. There have been reports that you can't use others in the US (AT&T, T-Mobile), but I've not tried that. I've had no troubles using a Cingular SIM in Europe.

does this method work for a us cellular customer? i have the electrify and plan to travel later this year. the whole idea for the world phone was to have it work there as well without the god awful international roaming.
i just use the *#*#4636#*#* code and put it in gsm/cmda auto? then how do i get it to recognize the sim when i get there?
i am using cm7
which an unlock code ( from Verizon - U have to unlock the first time ), Inc 2 can use GMS network ( both GPRS, Edge, 3G - HSDPA 900 / 2100 )
I'm using an unlocked inc 2 in Vietnam, with GSM network. It work well, both 3G and GPRS
PS : Using stock rom ( 2.3.3 ), AOKP and some other rom ICS doesn't work ( may be a part like sms doesn't work ).
FYI - being a VZW customer in good standing, I called up - using another phone line - Global Support & requested Sim unlocking, after verifying my identity - reading the disclaimer/emailing the disclosure docs, etc. & placing me on hold for a short while, came back & gave step-by-step instructions on inputting the 8 digit unlock code into the DI2 - the phone's screen displaying "unlocked" (it's good for life) then powered down & rebooted, and it was good to go.
I replaced the stock Vodafone SIM (note: it's not provisioned or activated) with an active China Mobile Sim card (that I normally used with an unlocked quad-band LG or Sony Ericsson "feature" phone) - turned off roaming data & mobile data access before switching over to GSM mode, and, it's success & ready - registered on AT&T's 3G network (CMCC's roaming partner, also with T-Mobile.)
I was able to send short codes to obtain my CM account balance, etc. (*#130# - Send for my overseas carrier)
Just returned from a weekend cruise to Bermuda (UK) trip and it registered with DigiCel for roaming on the island with GSM active only - (CellularOne is also available for roaming purposes) These are the same carrier for AT&T and T-Mobile Sims when going to this 21 miles island out in the Atlantic.
While on the cruise ship (Royal Caribbean) - it registered with their satellite based ship services for voice/SMS and GPRS (yes, it's slow 2G) services in GSM mode (it also worked in CDMA mode - beware of expensive Mobile Data pricing & per minutes calling rates ...)
FYI - back here on USA mainland now, prepaid AT&T Gophone & T-Mobile Sim cards worked on this unlocked DI2 (Edge/2G data only plus Voice/SMS) - it's easy to change APN settings to match AT&T or T-Mo if the account is provisioned for it - using both SkyRaider's custom ROM and Nijitsu's Sense ROM here.
If I get the t-mobile unlocked version, can I use with AT&T sim? Would I get LTE, HSPA or just EDGE?

If you get sim unlocked you can use an AT&T sim. You will be able to get GSM, GRPS, EDGE, HSPA, HSPA+, but no LTE as the LTE radio is software disabled on T-Mobile Note 2's. I remember seeing one Guy claim he had it but I don't remember who or where. Once T-Mobile activates their LTE then you will get LTE on AT&T also.
You may need to add AT&T APNs to use data but they are easy to find/add.

I'm frustrated already, I bought an AT&T SAMSUNG-SGH-I317 and also purchased an unlock code, phone was working just fine with 4g on AT&T ( Tested ) but after unlocking I just don't get service when I use a T Mobile or Simple Mobile SIM.
On the About Phone -> Status I do get "Network: T-Mobile/Simple Mobile" ( Depending on the SIM I use ), but I don't even get EDGE, I cant make calls, I get the annoying emergency calls only, its making me crazy. Is there a way to fix this issue?
I am in Tucson Arizona, a city where T-Mobile has upgraded their GSM frequency.
( I already added the APN settings, but I'm sure I don't need that to make calls, or get EDGE, I don't know what else to do to fix this ).
Thanks
Have you resolved your issue?

hey not sure if you resolved the issue but in the U.S all the NOTE 2s from the carrier should be used with the carrier that you bought from unless you get the international version N-7100 or 7105 because the AT&T NOTE 2s are missing the 1700 band for T MOBILE 4g.
But I read that if you enable aws you can get those bands. Check for "enable aws"

Has anyone used this phone with straight talk? do you need to unlock the phone or will their sim card work instantly?
I'm using my AT&T Optimus G Pro with Straight Talk. Works great. If it's a GSM phone you can use Straight Talk.

No. Their sim card will not work unless you have the phone network unlocked.

Yes mine is the AT&T version as well, did you need to unlock your phone? I have seen some saying you do and some saying you don't, but most people aren't on it it's just their thoughts. Since you are on, did you?
I didn't have to..that's the beauty of GSM phones. Most GSM doesn't necessarily have to be unlocked because most use the same frequencies. Also, I could use my Sim card on a T-Mobile phone, if it was GSM.

I bought mine already unlocked so I have had no issues whatsoever using Straight Talk. Love getting 4G for 45 a month.
Quick tip if you use straight talk all you need to order i straight talk att sim card. That gives you full 4g... If you use the straight talk t mobile sim you'll only get hspa +. If you have the t mobile sim then you'll need to unlock the phone and then set the phone up for T-Mobile network.
Add there is no need to unlock the phone.

I have the AT&T G Pro using Straight Talk. I had to network unlock mine. I verified this by putting the ST AT&T sim in before I unlocked it just to be sure and it did give me the "Invalid Sim" error. So this phone IS network locked. AT&T's provisioning is different than Straight Talks. So just because it's an AT&T phone and AT&T compatible sim doesn't necessarily mean it will just accept the sim without network unlocking.
I also have the AT&T G pro. ordered the at&t micro sim from ST and inserted and it worked without having to unlock the network lock. In fact on all of the AT&T branded phones i have used i have never ever had to unlock to use a ST sim card that used the at&t network.
In fact if you go to this link http://www.straighttalk.com/wps/portal/home/shop/sims
it will ask you if your phone is t-mob or AT&T and as long as you get the right sim for your phone, you should not have to unlock it.
I did have to edit my apn and follow the instructions in the thread below to get mms working

I didn't have to unlock my E980, as I used a AT&T compatible Straight Talk SIM. I get full LTE no troubles, but you have to fool with APNs to get MMS, as with most third-party carriers on other carrier's phones.
I have the North American 64gb Zenfone 2. I use AT&T's Share plan and I registered my phone in AT&T's system and it refuses to give me LTE. AT&T claims LTE is enabled on my sim but it doesn't work. When I pop in my brother's sim from an AT&T locked device I get LTE. I do not have any other AT&T locked devices in my house as I recently switched. Can anyone help please??
I am having the same kind of situation with Cricket which is owned by AT&T. My SIM had LTE with my LG Optimus G Pro but only 4G with my ZF2. It is the exact same SIM.
Im on straightalk i used a att sim with no issues on my NA asus zenfone 2, had perfect 4G(lte) signal on 06610.

If the indicater says "4g" that is LTE
OK, cool. My OGP showed LTE when it had the signal. I guess I was expecting the ZF2 to show the same.

Visit your nearest AT&T store and get the rep to delete your ZF2's IMEI from their system. If they won't allow you to, borrow someone else's phone and **get another SIM card** from them. Modifying your APN settings won't help at this point.

I think the phone only shows 4g.. My Nexus 4 (wth LTE Radio) shows LTE..
I am also using Cricket and my phone shows 4G symbol, with speedtest.net I get the 8Mbps down (Cricket caps 4g at that).
When I popped in my t-mobile sim (from the Nexus 4) it also showed 4G symbol, but i would get 26-34Mbps down (which is the 4G/LTE speed)
