How to SIM Unlock Sprint Galaxy S6 and S6 Edge, GSM fully working!

SIM Unlock Sprint Galaxy S6

If you have a Sprint Galaxy S6 or S6 Edge outside US (business or holiday trip, for example), and want to use it over a GSM network, then it’s possible to do that now. You would need root access on your Sprint S6, and then some apps we’ve shared below, and you’re good to go for it.

The main requirement is that your Sprint Galaxy S6 must be on OE2 firmware. It’s the latest, but if you don’t have it, go to Settings > About phone > System updates, and then tap on update button to get the OE2 OTA update now. Btw, you can also simply flash the OE2 firmware to update manually to update — see step 1 of our guide below.

Here’s how to SIM unlock Sprint Galaxy S6 for GSM carriers.
