Ian told me I should let you know something.
The to IMEIs i have for 750v2 have incorrect check digits. While TMobile doesn’t seem to care, both AT&T and Cricket consider the IMEI invalid if it’s wrong.
Basically, the IMEI was “invalid”, but when I calculated the check digit, and put that in, they recognized it and replied with:
Apologies! This 4G LTE Wireless Gateway GL-X750V2C4 is not compatible with the Cricket Network due to network changes. Please visit cricketwireless.com/3Gnetworkshutdown for more details or see your Cricket store rep.
I replied to your email with the details that I had sent to support - subject line “Just purchased a GL-X750V2C4, ATT reports imii invalid?”… immi because I seemed incapable of typing when I sent it.
