I was curious because I heard that the Droid Incredible 4G has a GSM radio in it so I did an experiment. I used a T-mobile micro SIM. I used the 4GLTE switch app for the Thunderbolt to access the hidden menu and I changed the radio mode to one that included GSM/W-CDMA. I popped in my T-mobile SIM and, presto, I got a T-mobile signal. I tested and I was able to make and receive calls and text messages. I had to manually set the APN for data to epc.tmobile.com and now I have EDGE data. I am sure an AT&T Sim will get HSPA+. The GSM appears unlocked now but hard to access. I am afraid, however, that once Verizon releases the update to make GSM roaming available, that it will be locked. Anyway, for now, you can pop in a GSM SIM and use your phone native.

if its like verizon other global settings (inc2) you can request the unlock code from them (they ll give you crap about using their intl plans first, but just yell until someone does it)

Works on AT&T with EDGE data as well. I haven't gotten HSPA (any variant) or AT&T LTE working, and I can't play with it too much because it's not my SIM
ATT LTE won't work because the frequencies are different from Verizon but I am surprised that HSPA didn't work. Did you use a setting that included W-CDMA? GSM only would likely mean Edge only.

Im afraid I cant get this to work. Does it require a rooted phone?
I have the app, I have a T Mobile micro sim installed. I click on the drop down menu (within the app) and choose the first menu item "Select radio band" and pick PCS (1900-MHz Band) and I get a "successful" prompt afterwards (only when the Tmo sim is installed btw).
I am unable to choose "GSM Only & GSM auto (PRL)" menu choices. Is this normal? I am able to choose GSM/WCDMA/LTE auto though. I dont get any sim error messages, but the phone never seems to want to camp on any GSM network.
You are looking in the wrong place. You need the drop down menu that includes GSM, W-CDMA, EVDO, LTE in various combinations. Select one with GSM in it. Also, I found that you need to have your Verizon SIM in first and then hot swap it with the t-mobile sim.
On the Rezound if you make a couple build.prop tweaks it fixes texting and data on GSM.

No, I was in the right place to begin with, I just thought it would be able to pick just gsm but it wont.
And you left out that piece of informationin bold, but still not working...
Can you give us your firmware & radio version, perhaps some phones have been updated to block this.
Anyone have any luck with this?
OP, is your phone stock? Rooted?
What if it has a bad ESN will this work or a way to make gsm work even with a bad ESN I'm asking because if Verizon does not have droid 3 s I will get this phone then go with at&t but will like to know if I can change the radio so I can so this

One additional thing I found was that I got it to work by hot swapping the Sims. It seems like the Verizon sim has to be in when the phone boots. Once it boots, use Phone Info to change the mode to GSM and then switch your sim.

I would think it should work. The ESN is used for the CDMA networks, the IMEI is used for GSM. Stick with GSM and you should be ok...
Dinc 4G now Global Ready
I was just chatting with a VZ rep online and was told that Verizon has already released a software update, thus making Dinc 4G officially global ready. Can anyone confirm/deny?
I asked her for a software version number which enables this, but she wasn't able to provide it.

Deny. No update has come out so far. You would be able to read about here if it had come out.

Anyway to activate 3G? Phone won't work on AT&T's 4G LTE. Only works on 3G !
AT&T says they have an LTE problem. My phone is the only one out of 4 on the
same acct. (all LTE) that doesn't work. Crazy!
Already had a Galaxy S3 I747 that did the same thing. No VM or rec'd a few hours
later & no Texts (but if I have texts out there not rec'd., I can send myself a text & everything
comes in) all of this on 4g & sporadic receipt of calls. AT&T says its a system problem not the phone.
AT&T put the phone on 3G it works, but their system keeps tossing it back to 4g LTE! AT&T no fix for it yet.

Do you have an LTE sim card?
Check your APN setting. It should be "pta" for access point name.
At&t LTE isn't a complete network. There's only one tower in my area that is LTE. And they do have system problems that can last for days.
Good question on the SIM Card. It has no identifying markings on it, as in the old cards used to have 3G on them. It looks like the old AT&T SIM CARD. If the LTE is the smaller SIM card, the answer is no.
My Galaxy S3 had the smaller card & still had the same problems. Right now (in settings... Mobile Network type) the phone jumps from UMTS
to HSPA:11 yet my wife's S2 reads LTE & no problems. Any phones out there that have the option of turning off 4G LTE besides the IPHONE?
APN is pta & problems since NOV. but just found out end of March it is an LTE problem after I began to contact the ppl at the top of the ladder at AT&T. Techs that I spoke with don't have a clue!
What I can't figure out is why out of 4 phones on the plan, I'm the only one with problems. If it were "just" a system problem it would logically affect all phones. Yet AT&T says it's an anomally with my line.
Wondering if another phone & new number would rectify it? lol
Try sim card swapping with a phone that reaches LTE network.
I recently bought the cell phone in US and am visiting India for a couple of months. When I tried using the GSM sims of both vodafone and airtel in in India I wasnt able to make any calls or rceiev any sms, despite of this being a WORLD PHONE.
I even rooted my device and by installing the APN MAnager I was able to install the Vodafone settings and to my surprise
Was able to get its 3g/Data services working.
However the Voice or the sms is still nit working.
The signalbar is showing just fine and so's the data connection symbol. However with the gsm sim in I keep gettin this NON VERIZON SIM ERROR icon on the top left.
Under the settings>MOBILE NETWORKS ive tried changIng them to both GLOBAL and GSM but still no luck yet.
Can anyone help me out with a network/sim unlock method, similar ti the ones avaialable on the tmibile and other phones.
Pretty sure the voice still uses CDMA. I believe that Verizon still only uses the LTE/GSM for data.

If thats true, then it wouldn't truly be a global phone now would it? GSM will work for voice, but you still need verizon's permission. It should work with a verizon sim, but you will pay through the nose. Now I thought the SIM was unlocked but I could be wrong. Also, even if it is unlocked, it still needs to be compatible with the network frequencies. I don't know what frequencies the VZW S4 has but you can google it.
This being a Dual Band mobile These are the bands that it supports..
CDMA 850
CDMA 1900
GSM 850
GSM 900
GSM 1800
GSM 1900
LTE 750
LTE 1700
WCDMA 850
WCDMA 1900
WCDMA 2100
Also on googling I came across some posts which said the people have managed to use there gsm sims in europe n korea and were able to get the voice n sms. For data they too had to play with th APN..
So what I am tryin to make out from this is we don have a solution to get the voice n sms working on gsm network
Pic showing the error message that I get when I try to make a call.
The second oic shows how my Network signals and data signals are showing just fine but still am not able to make any calls or sms.

I used my phone and put in a Straight Talk (AT&T) SIM and it works with data and voice after manually putting in the APN. If Verizon phone works on AT&T network, it should work with any network out there provided that the bands are supported by the phone.
I was under the same impression, as it worked for me too when I used the tmobile(gsm) sim with it. I was able to make calls only and data was restricted.
Where as with Vodafone IND its the other way round. Am not able to make/recieve calls or sms but data 3g is working just fine.
Confused what could the problem possibly be.

If rooted, you can use Titanium backup, and freeze 'Setup wizard'.
What good would it do if I freeze the setup..how do you suggest I proceed further after freezing..?

I recall needing to call verizon and get an unlock code for my old droid 2 global so that I could use non-verizon global sim cards in it. I believe you just needed to be a customer in good standing for at least 10 months, and could only do it once a year per line, or something.
Edit: A quick search showed a post claming it is already SIM unlocked, so never mind!
Since only my Data is working on my VZW GS4, that too after rooting and installing titanium and apn Manager.
Just wanted to confirm if I am thinking in the right direction, Is it possible that I may flash the Stock Rom for I9500(international Version) in my vzw GS4, and it would work with any international carrier around the world, cos currently am only able to use the Data/3g and Neither Voice nor SMS is working out here for me for GSM carriers like Vodafone and Airtel.
Id really appreciate if anyone can help me lookup a workaround for this..
I just made to run my port of Android Revolution HD 2.0 for i545 (I was porting it from i9505). Everything is working, except CDMA-networking. It's multilingual as well. If anybody wants - I could give it to test. I asked mike1996 for permission to port it, so it is permitted
I'm on AT&T,but just bought a rooted S4 off someone with a Verizon ROM on it. Would I just need to flash a AT&T ROM for the S4 to be able to get the SIM card to work with AT&T?
Any help appreciated.
Same here. My friend gave me his S4 today and it is Verizon and running on the stock ROM. However, I am on AT&T. From what I hear this phone comes factory unlocked so you just plug in the SIM and it should be okay. Is there anything else that I need to know if I want to use this phone as my main?

After a brief visit with AT&T today, they installed a SIM card from their carrier into my phone, but it would not get speeds grater than EDGE at the time. 3G may have been possible, but it didn't see it right away. Also, they had to update the APN settings in the Settings -> More settings -> Mobile networks -> Access Point Names. Lastly, after searching the internet, Verizon carrier locks the GSM in the states. In other words, they make it so you can use GSM OUTSIDE the US but not allow AT&T or T-Mobile SIMS to be used in their devices. This is a carrier lock, not SIM lock, so they can get around the whole "well, our phones are sold SIM unlocked" bs. After calling a level two tech support, he told me that there is no such thing as a carrier lock or SIM lock, and he could not give me a code. The phone was able to make a voice call and send a normal text, but data sucked.

Sorry to disagree, but my SCH-i545 works on the AT&T network with an AT&T SIM installed.
I only get Edge because that's the only band that VZ and AT&T has in common in this area. Swapping out a SIM isn't going to fix that.
What you're finding about GSM locks applies to pre-LTE phones. The LTE phones are not SIM locked, aren't carrier locked. Period.
purchased N9 LTE from ExpansysUSA knowing they were probably euro models. I have a tmobile data only sim and it was registered to this N9 when I got it as well. It worked and shows LTE.. Today I popped in my ATT sim and it showed LTE as well and i was pretty happy with that. i turned the device back off, popped back in the tmobile SIM and now it just shows Tmobile with full signal but DATA shows ! and wont connect to data.
I verified im still using the correct APN, even reset APN to defaults, I checked my Dialer code menu to make sure im set to LTE/GSM/CDMA preferred and it shows LTE status but then shows disconnected.
i feel like Tmobile is now blocking my Nexus 9 from connecting OR the sim has somehow messed up...
I swear i have the worst luck with tmobile sims always burning out.
OK it's working now. So weird how finicky T-Mobile sims and network connectivity are.
was it a data only sim? I got the same thing inserting my phone sim in my N9 but I believe that's because tmobile blocks tablets from working on phone sims.
I don't know about the Nexus 9, but I do know from experience the Galaxy Tab S LTE tablets cannot be used as phones on T-Mobile.
TMO will only give you a data SIM, so calls would need to be done VoIP/app based.
I'd guess the reason behind that might apply to the Nexus.
Oddly enough, TMO *used* to allow the LTE tablets to be used as phones.
But some sore loser in some forum complained about how it affected data plan pricing and so TMO clamped down on the data-only policy for tablets.
Btw, the LTE Euro Galaxy Tab S could only get HSPA/3G on TMO. LTE speeds were not possible.
