I've payed off my S8+ and have been told by Sprint it's showing unlocked on their end but I still get invalid sim when I insert T Mobile SIM. Also getting UICC unlock internal error 407.
Yes definitely skip the device register. Send me a PM with the IMEI of the phones in question.
If this isn't resolved in that time frame please reach back out here. Once that last payment is applied and cleared I can send the unlock and have it completed in a matter of minutes.
Is this in regards of my issue?
If so, phones have been paid in full.
We upgraded to the newer samsungs and we wouldnt have been able to upgrade if the devices werent paid in full.
