my galaxy grand prime's network has locked my sim and is asking for an unlock PIN

I bought the phone in India (in a most respected mall in Udaipur) and my Israeli sim was working fine with the Indian phone as long as i was staying in India. however, as soon as i got back to Israel (where my Sim card is from) the phone rejected the sim and asked for an unlocking PIN.
does anyone knows what it is and what can i do about it?

I think this one works search for this zx3box samsung unlocking device

Need help before buying Galaxy S7 Edge dual sim

Hello, I planning to buy a Galaxy S7 Edge with dual-sim and have read that originally only one sim of two can be active (other stays inactive). So my question would be : Is there a ROM in which would be active both sim-cards ? Thanks for little help.

That's correct. If you are on a call with SIM 1, SIM2 won't be inactive.
I'm not sure if there's any way to change this. I would guess it's a hardware/firmware function that cannot be modified.

Samsung S7 Edge permanently locked to AT&T (U.S.) carrier - Solution??

I traveled to another country and bought and linked a pre-paid SIM data card for my Samsung S7 Edge and incorrectly entered the network unlock code too many times, and now my phone is permanently locked to AT&T (U.S) network. I've contacted AT&T and they say there is nothing they can do... Is there a solution for this?

Might be best to post this in the AT&T thread?

AT&T S7 Edge... forbidden signal in place of the network signal

Hi
I've bought a second hand S7 and i didnt notice when I bought is that it was an AT&T version (G935A - Product code SM-G935AZDAATT to be precise).
The issue is that I've a circular forbidden sign in place of the network signal.
I'm living in Europe and I've a european Simcard.
The simcard is seen as it asked me the pin code and i can see in the application the specific one to access to my simcard.
My guess is that this phone is locked by AT&T... only AT&T sim card would work...
Is there any way to unlock the phone or is there any other workaround?
Thank a lot for your help
TBH
