AirVantage: Context is not Valid for the User


So I’m trying to register a device to AirVantage, and I copied the ICCID, IMEI, and FSN exactly, however I keep getting the error “context is not valid for the user” and I think they’re more related to the IMEI and FSN, but nothing seems to be posted here other than this: Unable to register mangOH red with WP8548 on Airvantage

It’s seems to be the same error but it was never solved. Has anyone else run into this?


Even I’m getting same error after entering correct entries. Has anyone figured out whats the root cause of the problem?
