How to Set a Device’s APN for Super SIM

How do I set the APN with AT Commands?

Refer to your device’s user manual to learn how to use AT commands then issue the following command to your device’s cellular modem:

AT+CGDCONT=1,"IP","super"

Setting the APN with AT commands via SMS

If you’re using a device that allows sending AT commands via SMS, you can use our SMS Commands API resource to send a machine-to-machine SMS to the Super SIM. You can use a command line tool such as curl or the Twilio CLI to transmit an API request which contains the AT command shown above.

例

In this example, AliceSmithSmartMeter is the unique name of the SIM as set in the Console. The AT command you use to set the APN is included in the Command field.

Here is the initial request, made via curl and containing the APN-setting AT command:

curl -X POST https://supersim.twilio.com/v1/SmsCommands \
  -d 'Sim=AliceSmithSmartMeter' \
  -d 'Payload=AT+CGDCONT=1,"IP","super"' \
  -u 'ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx:your_auth_token'

Here is the same request but this time made with the Twilio CLI. The --sim option’s argument is the Super SIM’s SID.

twilio api:supersim:v1:sms-commands:create \
  --sim HSxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx \
  --payload 'AT+CGDCONT=1,"IP","super"'

The request will eventually cause the following response to be posted to the callback URL. The sid, sim_sid, account_sid, and url fields will contain true values:

HTTP/1.1 202 ACCEPTED
Content-Type: application/json

{
  "sid": "HCxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  "sim_sid": "HSxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  "payload": "AT+CGDCONT=1,\"IP\",\"super\"",
  "status": "queued",
  "date_created": "2019-05-23T15:42:04Z",
  "date_updated": "2019-05-23T15:42:04Z",
  "account_sid": "ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  "url": "https://supersim.twilio.com/v1/SmsCommands/HCxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
}

Adding an APN with MCC and MNC values

Some versions of Android require you to provide a Mobile Country Code (MCC) and Mobile Network Code (MNC) for an APN. This is to help match the APN to the IMSI being used by the device. Every Super SIM has multiple IMSIs that it will switch between depending on the country in which the device has been deployed, or whether or not it has been able to connect in the past. To ensure that you can connect with any of the IMSIs used, please add all of the following APN and MCC-MNC combinations to your device.

Verify you’re connected to the network

You will know your device is correctly configured if you can send and receive data. Try pinging www.twilio.com, or open your favorite web browser and navigate to www.twilio.com/wireless/super-sim.

If your ping is unsuccessful or if you cannot load the web page, review the instructions above and make sure you have also enabled roaming on your device.
