If either of these commands returns
ERROR,
enter the command
AT+CEER
.
This command will return the reason for the error. The full list of errors can
be find in the AT command manual available at
. The most common errors involve
rejected activation or requested services not subscribed. Possible reasons
for these errors include:
1)
Incorrect APN – check with your service provider that the APN configured
in step 2 is correct.
2)
The data plan you are subscribed to does not support the type of
connection you are making. If you are subscribed to a LTE only data plan
but are trying to connect on 3G, you could be rejected.
3)
You are roaming on another network but your data plan does not allow
roaming. To check if you are roaming, enter the command
AT+CREG .
If
the modem rCREG: 1,5 then the modem is roaming on another
network.
4)
Your cellular data account may not have been activated or is currently
suspended. Your service provider may have sent you a SIM and not
activated your account or may have temporarily suspended your
account. Please contact your service provider to confirm the status of
your account.
