I live in Ukraine. Phone was purchased on Ebay.
When I insert SIM of my regional operator, the phone says that:
"Invalid SIM card. Network locked SIM card inserted."
"Network Lock: This device can be remotely unlocked if eligible.
Please use the "Device Unlock" application to unlock the device.
Make sure the device has an internet connectivity to use the "Device Unlock application".
But device unlock application is not compatible with my G920T.
What I need to do fot unlock the network?
