Trouble unlocking Straight Talk iPhone SE iOS v11.x w/ GPPLTE/RSIM
 

N00b to the forum...

I've been reading through the forums but don't exactly understand what I need to do. So I made the biggest mistake of taking out the SIM when it was working. Now when I'm trying to reinsert the SIM, it gives me a SIM error.

I got a new GPPLTE SIM which seems to look like the RSIM. Not if they're one the same but different branding. It appears from what I read that I need to update to iOS v12.2 in order for the SIM to work?!

And the exact steps are:
1. Turn off phone
2. Insert the SIM I want to use along with the GPPLTE SIM
3. Power on the phone & go through the wizard
4. Get to the final screen where it says SIM not recognized, press the home button > dial emergency > *5005*7672*00# > choose ICCID > enter the latest ICCID > and reboot phone?

You have the iccid, if you have what the iccid, number 2 is you have to find out what carrier is straight talk belong to like if it’s Verizon straight talk it have to unlock in different ways, if it’s att it’s have to be deferent ways, let me know you iccid and I can help you l, I hope I am from usa I unlock straight talk almost very day here

Once you put the sim inside with chip, you have to dial

I understand I'll need to get the latest ICCID from this forums, but how do I tell which major carrier my Straight Talk iPhone is on?

That shouldn't be an issue once the rsim unlocks it
