I have an N1 model and I activated it, but I can't do anything with it. When I try to dial out, I get a NO CARRIER response.- After you receive the NO CARRIER resopnse, send this command 'AT+CEER' to check the reason for the no carrier response. Then check the number in the Reference Guide.
- Make sure the modem is registered and getting a good signal: AT+CREG and AT+CSQ.
- Make sure the modem is activated and provisioned correctly.
