S4 Mini from Sprint CDMA to GSM - Galaxy S 4 Mini Q&A, Help & Troubleshooting

I managed to unlock S4 Mini L520 from Sprint using alyatim unlock app because I want to use it GSM outside USA, the issue here is that the phone does not have GSM/UMTS under network modes just CDMA. But after searching I found that the phone has GSM/UMTS bands on it so here's comes my question: can I flash an GSM modem from another GSM S4 mini and will it work? Or will it brick the device?

How do you unlock your phone ? Can you tell me ? My sph l520 can not reach any signal in Viet Nam although samsung sprint unlocker show phone is unlocked.

Try using a i257m stock ROM from sammobile with odin, that's is the north American gsm version. If it doesn't work then you could always flash back.

How to check if my phone supports LTE or not

I bought Galaxy Nexus from somewhere else. It was unlocked. So i am not sure if it supports LTE over Fido or not. I was thinking to request for LTE sim but wanted to confirm if my phone even supports it or not.
I do see H+ on my signal bar but i believe LTE is different. Can someone tell me any way to confirm if the device supports LTE or not. (without connecting to LTE network)
It's really simple.
If it is a gsm phone it does not have lte

Turn the phone off then remove the battery and read the label where the battery goes and if it reads GT-i9250 or GT-i950M it will not support LTE.

AFAIK the only LTE gNex are for Verizon & Sprint (CDMA in the US). If you look at Setting >> About Phone >> Baseband * it starts out I9250 it's the GSM model

Thats a more discrete answer
Model Number: GT-I9250
GT-i9250 "Maguro": GSM/HSPA+ variant. Features support for both AT&T's and T-Mobile's HSPA+ bands in the United States. This particular variant is currently sold SIM-unlocked by Google in the Play Store
Thanks though

Not that i like and want bash you, but can't you understand simple English?
I assume you understand English since you're from Canada.. If you don't understand English, then fine, i take back my words.
And a simple Google search would answer your question..

You do know what gsm and cdma are right?
You do have Google in Canada?

the "Baseband version " on my nexus 5 shows "M8974A-", does it support lte in US? It's an international unlocked version cell phone, and AFAIK, all the international version phones DONT support lte in US, is that real?

[Q] SGH-I747M - Unlocking and changing carrier networks

Hello guys! I'm using the I747M variant which I bought from Rogers about 8 months ago and I want to know if I can switch to other carriers network here in Canada via unlocking because Rogers' available phone plans are just a pain in the ass so I want to switch networks. So please kindly share any information regarding unlocking and changing carrier networks. Thanks in advance

Once unlocked, It is guaranteed to work with Bell and Telus.
Hope this helps :good:
Search for it, it's around here in the forums for free. You just need a simcard from the next provider you wish to go to.

How about on other networks such as Mobilicity? My mom is on a plan on Mobilicity and I also want the same plan because my phone is kinda useless without internet and not even a caller ID.
once unlocked it'd most likely work
but for the data part, i can't really say because different mhz on different carrier network..
so 70% chance that you will only get Edge in your area
Does anyone knows any information on how to change radio frequencies on a phone? I've seen some SG3 on ebay.ca that is labelled as "Pentaband" and could work with any carrier network here in Canada. Can someone please explain to me how does this work? And is it possible for my phone to be converted into a "Pentaband" phone?
Mobilicity does not use the same bands as Rogers, Bell or Telus for its HSPA/HSPA+ service. As Pcshano said, your phone would work on Mobilicity, but only on Edge.
You encounter the same problem as T-Mobile users in the US, and WIND and Videotron in Canada. See [WIP][BOUNTY] Enable 3G on 1700MHz for ATT Galaxy S3 i747 on efforts to enable HSPA on 1700MHz on the i747.

[Q] Unlocking SPH-L710 4.1.2 for use outside of the US

hey I'm new to the forums and rooting and I'm trying to unlock my Sprint SPH-L710 so that I can use it on a carrier outside of the states. If this thread has already been started sorry for the redundant post, if not can someone post how to unlock a SPH-L710 4.1.2 from Sprint so that I can use it in Canada please.
The Sprint S3 is a CDMA device, and not GSM. There is nothing to unlock for use in Canada. It doesn't accept a SIM card (though there is one embedded for LTE purposes in the U.S).

ok interesting, I was told that I could use it on a network here in Canada that also uses CDMA as long as it was unlocked but maybe they thought that I had the GSM version.

You might have to flash it to the carrier.

Tmobile S4, Verizon sim

Has anyone accomplished this? Running a Verizon sim in a unlocked Tmobile S4?
i am curious about this as well. i dont think the lte bands are the same though
Verizon is LTE 18. Not worried about that too much. I believe 3g will be all it will get
While a Verizon S4 will work with T-Mobile, I don't think a Verizon S4 will work with T-Mobile. Unless you can somehow enable CDMA radios, which technically don't exist in the gsm variants.

All S4's are actually gsm, including Sprint and Verizon. Both are unlock able and able to use on other carriers, so CDMA isn't really necessary

Yes I know many Sprint and Verizon smartphones are world phones, but Verizon still uses CDMA. So wouldn't you will still need a CDMA capable device if you plan to use it with Verizon? If it was the other way around, that's a different story

Yeah but that's why I was telling you.... if a Verizon S4 is gsm and not CDMA, why wouldn't a gsm work on Verizon if the same phone is gsm?
It's probably completely possible. Device wise.... the big problem would be getting Verizon to allow it on the network if it did
Well, i can't unlock the damn thing anyways. Tried 3 times to avail.
Just as soon as I Odin back the NH7 modem i loose the unlock. Very weird.

that's because it has both gsm and CDMA radios, while T-Mobile's does not. At least as far as we know. I think the gsm portion is there for when you travel for edge and HSPA connectivity and of course also for the use of LTE. If you insert a gsm sim card into a Verizon 'global' gsm/CDMA device, it will display a message "switching to Global mode," enabling full gsm mode. You still need a CDMA capable phone for activation on their network AFAIK.

I would give it a shot but don't have a different sim card to test
Don't sweat it. Im keeping it.
I tried my unlocked S4 with my girlfriend's Verizon SIM from her S5 and couldn't get it to connect to anything. I tried every different network mode I had available and couldn't get it to see any sort of a signal. I'm pretty sure I also tried to manually search for a network and saw Verizon as an option, but didn't end up getting anything out of it.

It probably picked up the LTE signal, since it is gsm
