Cancel your purchase as there is no way to make the CDMA Verizon able to work on a GSM network. It does have a sim slot but only for the Verizon LTE sim card. Only the newer Verizon phones (Note 2, Iphone 5, etc) have a sim slot that is already unlocked and would be able to be used on GSM carriers. Good luck and hopefully you can cancel your purchase in time.

Any ATT phone will work as long as you can get it unlocked or its already sim unlocked. The One X uses a microsim and you can just pop in your international sim once it is unlocked and be good to go.

Samsung Galaxy S 4 LTE SPH-L520 question

Ok so I was trying to unlock this samsung s 4 mini lte SPH-L520 but it seems like it's the only model of S 4 mini that i can't find an unlock code for, is this phone un-unlockable? and what is the difference between the SPH-L520 and all the other samsun s 4 mini?
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:

SPH-L520 can run on GSM carrier!
Yes, this is what Sprint told me last summer. But it's incorrect. I have a Sprint S4 mini that works on both Sprint and a TMobile MVNO. Voice, text, data (in refarmed area). Unlocking GSM can be done!

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.)

The Sprint network is CDMA and Three is GSM, right?

Please post the model of the tablet, and the carrier you wish to change it to.
Thanks.
Galaxy Tab 3 7.0 I want to use it three. My sim is three UK thanks
You cant use that tablet on europe at all, no CDMA carriers there, you need the ATT version and pay 19usd to unlock it.
THERE is NO way to get it working, the SIM slot on the sprint tablet is just for Sh1ts N Giggles..

What models does SPRINT support for the S4 Mini

Hello,
I would like to put an S4 mini on Sprint, but now confused as to which model(s) will work on it. Looks like one model from them is SPH-L520, but I read that the GT-I9195 will work also.
I also want to be able to get Marshmallow on it.
From what I am seeing, the only active and stable development is being done for the GT-I9195 .
Will this work on Sprint's CDMA network?
Thanks
Only the L520 will work on Sprint. The l520 has a few roms but they're not 100%. Also I think the gt is a GSM phone It will not work on Sprint. I suggest if your going to use Sprint. Find a different phone. Also if you still want one don't get a prepaid one it may not work on a postpaid.
i can confirm this...Sph-l520 is the ONLY s4 mini version that works with sprint network and it has almost zero development progress available for it..such as roms and tweaks!! as most of the "regular" sized phones do... but with a rooted stock 4.4.2 rom w xposed and a ton of other ad on apps as i do...its a pretty jiffy phone on sprints network...

Flash AT&T firmware on International Unlocked Galaxy S9

Hi,
Im a first time android user and recently bought a Samsung Galaxy S9 (International Version - SM G9600 - DUOS - Snapdragon). I need wifi calling very badly on At&T as my work and home both have bad reception so my purchase has handicapped me from making calls. I see a lot of forums talking about flashing At&T firmware on G960U VERSION. But i havent seen a single one talking about flashing it on g9600. Is it possible? I compared the specs and every hardware looks same except dual sim option. Will I brick my phone if i attempt it? Please suggest im in need to help from the pro community.
Regards.
