I understand your frustration. You'll need a working Sprint SIM for the unlock to work successfully.
I'm not in the US right now. I'm not use sprint network probably half year. After oreo update phone locked and all that I have its old sprint sim
Take the Sprint SIM out of the phone. Wipe the SIM down, making sure there are no fingerprints on it. Put it back in the phone. Does the phone recognize it?
When I turn on with sprint sim, phone asks for registration "This device has not been registered with an account" Sim is working, but phone is locked
Alright, what message do you get if you put in the SIM for your current carrier? Does it show locked to Sprint?
Ok, put the Sprint SIM back in it, connect it to WiFi, and keep it powered on. I'll submit another ticket, as soon as you let me know it's set up.
The ticket can take 2 days. But I'll give you a ticket number for you to check on tomorrow.
The new ticket number is SD5961261. You can check on the ticket tomorrow. Unfortunately, I won't be here to do the proactive check for you.
I have a Sprint LG V20 with an active account, but I wish to unlock my phone for overseas travel.
I just called Sprint to have my LG V20 unlocked, but the agent I spoke to claim that it already is. However, when I placed another non-Sprint SIM from a family member into the phone, the phone shows 'Invalid SIM'. I suspect that it was not properly unlocked. Assistance would be much appreciated!
