SIMs and APNs

APN¶
Access Point Name.
Note: for all u-blox C030 boards except the N2xx flavour, a SIM is built into the board and will gain service automatically using the Jersey Telecom APN "jtm2m".
SIM & APN¶
A SIM can connect to one or many APNs. If you don't know where your SIM came from or what services the plan offers then you'll need to try a couple different APNs. The same goes for Sara G (2.5G GSM/GPRS) and LISA U (3.75G UMTS/HSPA(+)) radios. A SIM may be compatible with services for one or both. This may vary by carrier and plan.
| Carrier | APN | Country | Sara G | Lisa U |

| "phone" | US | X |
