configured. To set the APN enter the following commands:
AT+COPS=2 modem will return OK

Contact your service provider for the correct APN name. If you can’t get your
APN name from your service provider you can try the following APN names:
AT&T users: m2m.com.attz, or broadband
T-Mobile users: m2mglobal, fast.t-mobile.com, or epc.tmobile.com.
