MC7455 IMEI rejected by ATT and Verizon?

Post by ericm » Tue Dec 04, 2018 9:17 pm

Feeling a bit foolish about now -- I'm thinking I'm doing something wrong.

The IMEI number printed on the 7455 and the invoice is identical. When I type that number into the ATT or Verizon IMEI number check, it comes back as being incompatible with their system.

Any idea what I'm doing wrong?

Are you attempting to get the MC7455 provisioned thru the carrier?

Most users of the MC7455 run the Generic firmware (which comes on the modem) and a SIM card from any active plan. No provisioning or carrier intervention is necessary.

I was thinking that ATT would have to activate the SIM -- am I mistaken that the activation process involves the IMEI number? I've flashed the WE-826T with the WiFiX custom GoldenOrb firmware and I was going to input the "broadband" and other strings. At that point, I wanted to see make sure I would not have a problem -- so I did the IMEI check.

Should I pick up a ATT unused SIM and proceed with the process? Sorry for my ignorant questions.....

There are various methods. Some activate another old phone on their plan, then use the SIM from the phone and use it for the router.

Watch for a PM from me.
