IMEI Registration Apparently Dropped
I have an Alcatel Tetra (Model 5041C) given to me in May of 2019 by a friend. He obtained it from AT&T on a prepaid plan.
Since September of 2019 I have be trying to unlock the device. At first the AT&T Unlock Website reported, Looks like the IMEI number you entered doesn’t match an AT&T device.
Then in October of 2019, AT&T accepted the IMEI number but stated, ...it hasn't been active for at least six months of paid service.
I have been trying to obtain an unlock code every month since then without success. Today, though, that Looks like the IMEI number you entered doesn’t match an AT&T device has returned.
Has AT&T unregistered that IMEI number? How can I get the unlock code for this Alcatel cellphone?
