Issue connecting to Sprint Towers, Not registering
Posted: Fri Sep 04, 2020 8:02 pm
Hey everyone,
I've been trying all day to connect my Caylx sim to a different sprint tower. I'm using a Cradlepoint CRA850, with an EM7565 modem. Setup works on a different tower, but that tower lost B41 and is now super slow.
I cannot get the modem to properly register against the APN:r.ispsn, it just continues to say that the EMM state is "Deregistered Attach Needed".
After hours of mucking around I was able to get it to register to the tower using the APN: "otasn", and receive an IP address, but no data flows through the connection. Once I switch it back to r.ispsn and reset the modem, it switched back to dregistered.
When it's not registered, I've tried kicking the registration with AT+CGATT=1 but every time I do that it seems to cause the modem to reboot.
AT+COPS? shows 0
AT+cops?= shows "cops: (1,"Sprint","Sprint","310120",7),(1,"310 830","310 830","310830",7),(3,"Sprint","Sprint","311490",7),(1,"Sprint",
"Sprint","312530",7),(1,"311 882","311 882","311882",7),,(0,1,2,3,4),(0,1,2)"
attempting to manually set the AT+cops to 1,2"Sprint",7 gives an error
at+creg? shows "+CREG: 1,2"
Anybody have any ideas?
