They automatically unlock it once it’s paid off. They have a disclaimer that it needs to stay on the network for 60 days after it’s paid off, but I think that’s a CYA because mine was unlocked within a day of the last payment.
I just checked and I have 6 unlocked phones on my account and never requested any of them.
Hold up,
2024-1994=30 years
Since a century is 100 years, 1/4 would be 100/4=25 years
How did you get 32 years equals a quarter century?
