[How To] GSM unlock S6

Recommended Posts

I unlocked s6, enable gsm,but after hard reset it set on CDMA again,how to save gsm ? I mean after hard reset will stay in gsm.

Update to the latest firmware and you won't need to enter servicemenu every time you want to enable GSM.

You're on the wrong firmware if LTE/UMTS/GSM isn't present in options.

 

Get the latest, stock, unrooted rom and GSM will work again.

 

That easy, Dave.

Using the Change APN app....anyone got this before? Using T-Mobile sim.

"unable to view access point name settings. Access is restricted for the current user profile"

I've tested with T-mobile sim On S6 and Note 5 from US Cell and data/voice works. but not text. Any insights on how to fix. Text fails. Using google hangouts as default text also fails.

It's undoubtedly an APN issue. Make sure you have the correct one. If you still struggle try chomp SMS where you can put the APN directly in the app.

It's not an APN issue as I have stated data works fine. APN is for data and picture messaging because they use MMSC and MMS proxy. This is just simple SMS. I can receive SMS text but cannot compose and send any SMS without it failing using T-Mobile and Lycamobile (2 different carriers using T-Mobile towers).

Has anyone tried this with Cricket Wireless? If so what did you do?

 

I don't have the USC GS6 anymore, I got a Verizon GS6 now but...

Cricket is just AT&T re seller, So will work perfectly as advertised in this forum. The same with all the other GSM carriers.

Off-Topic: I just got a Cricket sim last week, whenever I get around to activating it, I'm going to use it for data. Cricket is the first i've seen who are now actually offering true unlimited LTE (throttled to about 8mbps but that's plenty enough for me!!).

I am connected to tracfone using a tmobile compatible sim in my uscc 6 edge plus. I can set apn for both tmobile and tracfone. The only problem is I can't receive calls and can barely make them. I can see that it's having a hard time switching to just edge or 3g to make call. I am located in washington state in the yakima valley. Any help?

You should probably contact Tracfone about this.  This forum is for US Cellular devices and US Cellular service.  While the topic of this thread is about using USCC hardware on non-USCC networks, we don't know how to troubleshoot your problem since you're not on USCC's network.

Congratulations. Would you like to share your solution? Or are you just telling us that it's fixed for no reason?

It was solved in one of the first posts in the thread i just didn't try it until now. 3Gswitcher app so i can switch back and fourth between 3g and 4g. I could only make or receive calls on 3g. I am using unlocked an unlocked USCC galaxy edge plus on tracfone plan with a tmobile compatible nano sim card
