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.

Hopefully a custom ROM can unlock the ability to use GSM networks in the United States!

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.

Check the specs, if it said gsm 850,1900 it should be able to use with in the US. Just have to sim unlock it first in order to use.

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?

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.

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.
I have Verizon, a Motorola Razr (Not MAXX) and it is crapping out on me, running slow, not sending picture messages etc.
My boyfriend has a trading post type store and he bought a brand new Galaxy S3 but it's through AT&T. When I put my SIM card in the S3 it asked for a SIM Pin for unlocking.
I have experience rooting a Nook Tablet so with some directions I'll probably be able to do it, I just don't know where to even start. Do I just unlock the phone or is there a way to switch it over?
Thanks!!

It seems like you just need an unlock code to use it with your old SIM.

So I called AT&T and they gave me the unlock code. I used it and it said unlocking the mobile network was successful. I tried to make a call and it said that only emergency calls were available. I restarted the phone and when making a call it said no mobile network can be found.
Ohhh you are putting a Verizon sim card in it? I don't think that will work since Verizon's network and lte use different technologies than at&t and the sim card is encoded to use the respective technology :X

That would mean you can insert a gsm sim card into the RAZR maxx because it is a world phone. However, the at&t s3 does not support CDMA, which is the network technology that Verizon uses. That's probably why you are getting no mobile network when inserting your Verizon SIM card in the AT&T s3.
Sent from my SGH-I747 using xda premium
The gsm sim that comes in Verizon global phones is there so when you travel out of the country you can use a cdma phone in countries that have a primary backbone that is gsm. In the us your phone uses Verizon's cdma network. If it does not see that network it will then look to the sim card to see if global gsm networks are detected.
To my knowledge this is going to be a no-go. If you have not done so, clean up your sd card, toss a factory data reset at your razor. These android phones are pretty tough.

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.

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.

Well one rather big difference of the Sprint S4 mini (SPH-L520) versus the international models (GT-I919X) is that it uses CDMA networks rather than GSM. I am not sure if you can use it on GSM networks with a sim card. I do, however, know that the Verizon version (SCH-I435) which is also CDMA can be unlocked and used on GSM networks. I used the app RegionLock Away from the play store (and here on xda) to unlock and it worked with an AT&T sim card.

sprint sph-l520 NOT a worldphone
I talked with the Sprint folks.
The Sprint variant has a sim tray that is just for the data sim (UICC card) not a GSM sim. And it is NOT a worldphone.
So even if you put a GSM sim in it, the radio is not looking for GSM towers (only CDMA).
But the Verizon version IS a world phone, which is why "wiisixtyfour" was able to unlock his.
That being said, since Samsung has made several versions that do have this capability, it seems possible that if someone modifies these things it could work:
-Modified sprint radio to receive GSM radio frequencies/signals (maybe copying the Verizon one?)
-Modified PRL to look for GSM towers
-Modified SIM tray communication to recognize not just DATA sims but GSM sims as well
I have no idea how to do any of these. But would love it if someone a lot smarter than me can take a stab at it. :cyclops:

avgtuhm, that's only true if you can explain how it was done and it can be replicated.
What does #0111*NETWORKCODE accomplish?
First off, my apologies if I am in error about GSM functioning on my phone.
I will explain what I've done with my Sprint S4 mini and maybe you/someone can tell what is happening. But this is why I thought GSM was/is working on my phone, until supermaxkato questioned this. (Note: I am not a developer.)
My S4 mini is active with Sprint. If I put a GSM SIM in it, of course it does nothing. Try to make a phone call and I get an automated message that it cannot be completed. But after doing the following, I can make calls, send texts, use mobile data.
I powered on with GSM SIM in phone. Entered #0111*NETWORKCODE for my phone in the dialer and hit call button. After this voice, text, data work. However, phone shows "Invalid SIM" in the notifications and the calls and texts come from my Sprint phone vs. the number associated with my GSM SIM. (I didn't realize this until testing last night.)
So did the code just make it so the SIM tray ignores the GSM SIM and functions on Sprint network? (again.. before entering the codes, no calling/texting/data worked with GSM SIM in the phone)
Same results on 2 activated Galaxy phones. Unsuccessful on non-activated S4 Mini.
I am not tech savvy but if anyone wants me to check something on my phone, I will try to get you the information. (I do not have a rooted/modified phone.)
Again, sorry for my mistaken report of success. In retrospect, I should have known it couldn't be that easy.
(Earlier this year, I WAS told by a developer in Colorado that there has been limited success with Sprint S4 minis being unlocked for GSM both internationally and domestic. And a Sprint rep recently told me that this phone can be unlocked internationally for GSM, although I see that it is not on their list of unlockable phones.)

Not really. I had my note 3 from sorint running on tmobile. But i only had edge and slow service bad voice calling. This phones hardware bands and software bands arent really meant for it. I had to modify the carrier info in my phone to get on tmobile alone. But ince there sorint didnt work anymore. A domestic sim card unlock isnt as easy as with gsm. With gsm the carrier info is practically just in the sim card. But with sprint CDMA it in the phone. Right now sprint sims are just for the lte and spark network. Not the actual use of the phone. So youre kinda out of luck sorry.
