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.
Oops from my Incredible 2 using xda premium
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.

The Sprint version is being advertised as an international phone, and comes with a Sprint SIM card pre-installed, and what appears to be a security strap, making it difficult to remove.
Before traveling internationally, you can call Sprint ahead of time to have them active their SIM card, and for the low low price of $1.99/minute, you can use overseas GSM networks to make phone calls, and in many cases, data access.
Of course I'd like to buy a pay-as-you-go SIM card and install that for much more reasonable rates while overseas, but I'm not sure if it's as simple as plugging in a different SIM card.
I had read that the Rogers version of the phone required...something to active the SIM slot, and even then seemed not to work for data via 3G.
Anybody else have the Sprint version? Played with GSM yet?
I'm a little apprehensive to start tearing into it to remove their SIM card just yet...
The GSM is 2G only, no 3G.
Well my buddy has a AT&T sim card that i put in my TP2 but it did not work. I switch the phone to GSM only but it did not pick up a network. I also put that sprint sim on his phone but it had no network either. According to the manual its lock from going to a gsm network on the USA.

good to know.
I read in the manual that it was not usable on US GSM networks too, but I assumed that was because they never intended for you to remove the Sprint SIM card, so of course the Sprint SIM card wouldn't work domestically.
So it seems the Sprint phone can be unlocked for GSM just like the Telus phones, but I haven't read of any success getting GSM 3G to work w/ an unlock code.

It got a signal. But could not pick up carrier or anything just had signal and said searching in notification bar.
But verizon is CDMA so it did not supprise me.
I see that the LTE radio bands are in there, no surprise there. But I also see WCDMA radio bands too. Does that mean that our Galaxy Note 2 have WCDMA radio too? Or is this just an firmware that Samsung uses across all Galaxy Note 2 devices?

I think we have CDMA also....not that it does much for us as verizon and sprint require the imei to be loaded into their systems.
WCDMA != CDMA by the way. WCDMA is 3G/4G GSM (aka UMTS)
CDMA is a competitor to GSM. It is used by mainly North American and Japanese/Chinese cell phone companies.
I know Verizon and Sprint in the US and AU in Japan use CDMA. Most of the world uses GSM.
All though thinking about it while we may have the CDMA radio, assuming it is the same chip as the GSM and LTE radio then they may have just not sokdered the connections. Seen that before with FM radios built into the bluetooth chip on the Atrix 4G
Which of the bands are our 4G?
Love learning.

No problems. This kinda stuff is my hobby. Maybe some day I can get a job at a cell phone company as a technician or something.
I can confirm this works, but I could not get data. I got signal and a carrier name with both an AT&T sim and a Straight Talk (AT&T) sim. It would not load APNs, and I don't have the APN for regular AT&T so I tried with the Straight Talk, put in their APN and still got no data. Neither sim is active currently. It did allow me to call 611 on both sims.

Hi,
I purchased Verizon HTC One from craigslist it was mentioned that it is pre-unlocked phone. I have used T-Mobile sim and it is working however when I tried AT&T sim in it that didn't work. It shows at top that network is AT&T but I am unable to make or receive calls. I was able to use data on AT&T's edge network ( though my sim is LTE). I know that both T-Mobile and AT&T are GSM networks and this phone is CDMA/GSM. Does anybody else using AT&T sim on Verizon HTC One? Do I have to change some kind of settings??

Hello,
I have the same Verizon phone and I'm using T-mobile network, but I can't get data started. What APN settings did you use? If
you could please help I would greatly appreciate it.

You will only get edge because Verizon blocked some of the bands that you would need for hspa speeds.

Weird because I have a straight talk att and tmobile SIM card with correct apn's set and I only get edge. I know tmobile reformed my area to the 1900 band too. If I pop those SIM cards in my droid DNA I can pick up HSPA speeds with the same apn settings.

I think it has only the 1900 and 800 band. Not the 850, which you also need for 3g. Or Verizon blocked those bands despite the phone being factory unlocked.

There's an app called "LTE On/Off", not sure if can download from play store, but included with certain Roms. It allows you to pick different bands. You can select HSPCA/GSM etc. Maybe this will help with other networks??
I'm not sure. On android central I have a thread there about the Verizon one. A person there says he tried it on straight talk with an att SIM and got hspa speeds. I tried both an att and tmobile SIM card in my Verizon one and only got edge with both apn settings. And tmobile rolled out the new bands where I live too. At the time my one was not rooted so I didn't have that app.

could you flash a new radio? Seems like that might help.. and if the hardware is the same and you get the bootloader unlocked, root the device, and achieve s-off could you re-flash firmware, radios, hboot and rom could it potentially operate as a modified at&t (or other gsm) htc one? sorry if this is completely wrong I'm not a firmware guy.. I know basics of rom's and installations that's about it just throwing an idea out there...
Not sure, but you could unlock your cid setting it to all 1's and flash a gsm edition Rom or ruu, flash radios too. Not sure weather it would work or not depending on the Verizon model hardware but all that stuff you can do.
Turns out the guy on android central was wrong, he was also getting edge data but didn't know it.

Are any of you who are trying to use the phone on AT&T running a custom rom, e.g. Cyanogenmod or Santod's Global Edition?
My one max works on at&t fine once you add the apn settings for at&t.
The Verizon one does not have the same frequiences unlocked that require you to have 3g. The DNA has pretty much similar radio frequiences and gets hspa but the HTC one has those bands locked so you only get edge, even with apn settings.

Great. It's usage like this that was a big contributor toward the unlimited data plans going away. Thanks. This is why we can't have nice things.
Back on topic, I'm curious as well if flashing new radios would do the trick.
They would have to be fully compatible and I'm not sure they would be. Maybe possible but I have not tried. Mainly one reason why they stopped selling the DNA.

So the consensus here is that you cant do any better than Edge service when using AT&T SIM in a VZW HTC One?
See, I just swapped my Note 3 AT&T for this phone, and Id like to be able to use data. I use AT&T prepaid but my Note was always able to pickup HSPA and LTE
Have any of you ever tried doing a factory reset from hboot? That will clear out all of the network settings from verizon, and force the phone to be reprogramed from the sim.

Hi,
I am thinking about moving my Galaxy S4 and moto RAZR from Verizon wireless to iwireless (a t-mobile affiliate). I understand that I need to unlock my phone but I am unable to find out if I move it to iwireless if I will still have 4G data. The iwireless sales rep said that I will still have voice and 2.5G service but couldn't tell me if I would still have 4G.
I was looking at this table I found on a site explaining how to unlock the phone but I don't know enough about the subject to make an informed decision.
Samsung Galaxy S4
Can someone confirm whether or not my Verizon S4 or RAZR can be unlocked to work with the iwireless/t-mobile 4G network?

It seems as though your grasp of the subject is strong enough to know that it might work as you'd like - and it might not. You need to call back and ask to speak to a CSR that actually knows what bands their service works on so they can give you accurate information. That's kind of their job...
Also -
Verizon LTE operates on Band 13 while T-Mob operates on Band 17, both of which carry completely different spectrums; this means no LTE on either of your unlocked phones.There's a slim possibility that you will get intermittent 3G but the most likely scenario is that you will get talk, text and 2G / 2.5G only.
Band 17? My Verizon branded S4 is getting T-Mobile LTE. I'm fairly sure its on band 4.
T-mobile is band 4 which is 1700/2100 mhz. The Verizon s4 is not capable of 1700mhz. But if you are getting 4G it may be because your area is using 2100 mhz. I am specifically moving to iwireless and I was told they use the 1700 mhz band.

Yes, I think all Verizon LTE capable phones are unlocked.
The I545 (Verizon S4) can receive LTE on band 4. T-Mobile serves LTE on band 4. The coincidence works well.

My RAZR MAXX HD definitely wasn't SIM unlocked... For the life of me I couldn't get it to work when I moved to ATT from Verizon... Not even GSM would work.
I just need to get some clarification from you guys. Are your VZW phones bought in the US and being in the US on t-mobile's or iwireless's 4g network. Because after I made the first post I went to the phone unlocking place in my local mall and talked to there techs, they said that the VZW S4 will not get 4g. I have also been doing extensive searches online and keep finding half saying it will work and half saying it won't. I have a feeling that the ones that work are working outside of the US as I found posts saying as such.
I read some where that the razr you had to flash the radio FW to get GSM to work properly.

I got my vzw S4 off craigslist but 99% sure it was purchased in the USA. I'm on T-Mobile's $50/mo plan.
Verizon's LTE phones are sim unlocked due to an agreement with the FCC when vzw purchased some bandwidth.
I think there was an update around 03/2014 that enabled band 4 on the I545. Then had to make some apn changes and tell the modem to use gsm/lte on band 4.
The one quirk I have is it will say "no service" after a reboot and until I make or receive a voice call. Then I get the "T-Mobile" instead of "no service" and things work as they should.

I was just at iwireless today and tested my phone with their network and was unable to get it to work. iwireless is a t-mobile affiliate but they do not use 4G LTE in my area. Their system runs on a 3.8G 1700MHz which the VZW S4 does not have. I am told that they will be starting to switch all the 2G radios in the area to 4G LTE later this year, which should work with my VZW S4. So I am just going to have to wait till the end of the year and go back and test it again.

My RAZR MAXX HD definitely wasn't SIM unlocked... For the life of me I couldn't get it to work when I moved to ATT from Verizon... Not even GSM would work.

That phone was before VZW bought the band 4 spectrum and cut the deal with the FCC. All VZW LTE phones are SIM unlocked. Any AWS capable VZW phone is SIM unlocked and can use LTE on band 4. The S4 got it with an update last year.
I am probably going to do the $30 plan soon and plan to use my VZW S4. I am not going to port my number right away in case the service in my area sucks (doubtful, live in DFW in dense surburbia).
I went out off town this weekend and went to a t-mobile store and was able to get 4g service after adding the correct APN. But it is too bad that iwireless that is in my area does not use that band yet, they are staring to upgrade to that band later this year. Until then my s4 will only get edge service.

I was able to get H+ on my s4 from Verizon to tmobile by changing the network mode to global and the App to fast.T-mobile.com

With the announcement of the T Mobile $100 2 line unlimited everything, I'm also interested in bringing my Verizon S4 MDK boot loader phone to T Mobile, but want to do my research first-- is it as simple as signing up for T Mobile and getting one of their SIMs and then-- would I be able to flash any of the ROMs in the S4 T Mobile Dev forum or is the T Mobile S4 a completely different device? Any caveats? Would I have to LokiDoki after the flash? Would I need to flash a T Mobile specific radio too (currently on i545vrufnk1)? Or is that all just overcomplicating things? Would i be able to just adjust the APNs on my current ROM after inserting a T Mobile SIM?

Quick reply to my post and for anyone else interested-- there's a post here that talks about using a 4.4.2 T-Mobile ROM by Fenny on the a Verizon S4: http://forum.xda-developers.com/showthread.php?p=57453019 I've tried it and LTE works great, MMS works properly, phone calls work as well. I'm on the Verizon i545vruamdk bootloader and Verizon i545vrufnk1 radio. The ROM is a T-Mobile m919uvufnb4 by Fenny.

Any idea why the G5 I have that was unlocked by Sprint OTA will not work with my AT&T SIM? The phone shows the "Bad SIM" icon and refuses to work. I checked the ##DATA# settings, and LTE + LTE roaming are on? Any ideas? Thanks!
I'm no expert, but I believe the Sprint network and phone antennas are 180 degrees different from AT&T.
- Sprint uses CDMA; AT&T uses GSM/UMTS/HSPA+
- Sprint 3G uses bands 10 and 1; AT&T uses bands 2 and 5
- Sprint 4G uses bands 25, 26, and 41; AT&T uses 2, 4, 12, and 17.
Unlocked or not, a Sprint phone antenna is not designed to connect to the same networks as an AT&T phone.
I know there many more knowledgeable than I here, so I welcome corrections.
Change band priority
4 and 2 are from AT&T
Put 1 and 2
And Select GSM on network preference
Open Dial 5689#*992#
Field test
Módem settings
RAT selection and select
GSM/ WCDMA / LTE Auto
@adop_19 Don't get the field test menu when typing the above code. Get "HiddenMENU' with the following;
Device Test
ELT Test
Factory Reset
Log Service
WVDRM Keybox
Any ideas? This is puzzling as Sprint swears the device has been unlocked OTA? There are others on this forum using the same device on Cricket, and thus I believe it should work on AT&T? I am at a loss? Thanks.

Mmmm , is rare, Maybe not is unlocked

Yours may have only gotten internationally unlocked. Sprint has 2 unlocks. They sneakily volunteer information and assume you mean international unlock only. You have to specify domestic unlock to get it to work in the US if you unlock through Sprint's OTA. It does have the bands to support GSM in the US. Even the G4 does. I unlocked one and have it running on T-Mobile. Talk and text only since it didn't give me the APN menu then, but that's ok, it stays near wifi. If you can't get back in touch with Sprint, there are other ways to get it done without them. You'd have to PM me for that part.
Just Reread The Title. It sounds Like they didnt really domestically unlock it.
Is your agreement with sprint for the device fullfilled?

Fyi, being domestic unlocked vs released by sprint are 2 different things

Need help with unlocking G5.

Yes, it only gets Talk, text and 3G and you can only get it working by swapping your SIM. Verizon won't do it if you ask them

There is a free guide to try in dev section
Piggy backing this thread. I've had my LG G5 domestically unlocked by Sprint. I've put in both a ATT and T-mboile sim and added the correct APNs. Calls work so it is definitely unlocked but I can't for the life of me get data to turn on. Not even 3g. Any ideas? Sprint service is deactivated so that shouldn't interfere with the LTE and data. Bands 2,3 ,4, 5, 7 and 12 are enabled according to ##DATA# LTE is enabled. LTE roaming is enabled as well in there.
In network mode I have Automatic, LTE/CDMA, CDMA and GSM/UTMS only. Currently set to automatic. I also tried gsm/utms but nothing.
In LTE discovery I noticed it found LTE band 12 for a second but just connected to UTMS with no data. Everything shows as not roaming (maybe that is the issue?! since these non sprint lte bands are considered roaming bands or something). Reception is good in the area. I usually hit 20mbps+ down in this location with the same sim using band 4.
Help please!
I have a Sprint LG G5 (LS992) and before the ZVC update, I was able to get LTE coverage in my house all the time... Now, after the update disabling my hiddenmenu app trick, I was forced to pay for remote sim unlock for the phone, and everything went great, I have full functionality, and pretty good speeds, using AT&T service now, but I don't get LTE anymore when i'm home... I haven't tried it anywhere else, that is my next move... Just wondering if there was something I missed... I set up the AT&T APN correctly from the ATT website apn settings, have gone through all the hidden menu settings, RAT Selection gsm/wcdma/lte auto, I dunno what I'm missing, other than it just wont work on LTE anymore.
