I was successfully able to activate the X750 after the AT&T/Cricket Shutdown
1* I visited https://www.fakepersongenerator.com/imei-generator to generate a Compatible iPhone IMEI I decided on a iPhone 11 IMEI
2* I reflashed the unit with R00ter firmware https://www.ofmodemsandmen.com/
3* I proceeded to follow the recommendation from @silkweb and did a Custom AT Startup Command with the new IMEI generated AT +EGMR=1,7,“IMEI”
also be sure to Enable Custom AT Startup Command at Connection
Works great the only issue is after every 5 minutes or so there seems to be a drop in the connection but it reconnects shortly after I’m new with this particular device so I’m unsure if this is a ongoing problem with anyone else besides that its working pretty well
