Hello guys.
My client brought such a problem. SM-J600F said that his mother bought this device from Arabia. The phone was blocked by a cellular operator. I considered the blocker cat via ****** to unlock the device, but the device only works in 2G mode. when I switch to 3/2 or LTE / 3G / 2G network disappears ... resetting settings ... flashing different firmware didn’t help eat what kind of solution guys ??
