Super SIM: APN Configuration

What's the Super SIM APN?

super

You will need to configure the device into which you have fitted your Super SIM with the identity of the server through which it will transfer data. This is the SIM’s configured Access Point Name (APN).

If you know how to configure the APN on your device, go ahead and make the change now. If not, here are some guides to help you:

That’s all you need to configure your device.

The Twilio APN does not require any authentication, so you should leave the username and password fields blank.

In addition to configuring the APN on your device, ensure that you have roaming enabled.

How do I set the APN with AT Commands?

Refer to your device’s user manual for how to use AT Commands.

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 Commands resource to send a machine-to-machine SMS to the Super SIM. You can use a command line tool such as curl to transmit an API request which contains the AT command shown above.

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/Commands \
  -d 'Sim=AliceSmithSmartMeter' \
  -d 'Command=AT%2BCGDCONT%3D1%2C%22IP%22%2C%22super%22' \
  -u 'ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx:your_auth_token'

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",
  "command": "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/Commands/HCxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
}

Many devices do not support setting the APN via SMS. Refer to your device’s user manual to see if it is permitted and how to format the message.

Where do I set the APN on my Android device?

Depending on your version of the Android OS, you set the APN by doing the following:

  1. Go to Settings > More settings > Cellular networks > Access point names
  2. Tap the menu or + icon to edit an access point.
  3. Enter Twilio under APN and enter super under APN.
  4. Tap your new Twilio APN to set it as your active APN.

Adding an APN with the MCC and MNC

Some versions of Android require you to indicate the MCC and MNC for an APN. This is to help match the APN to the IMSI being used by the device. Each Super SIM has multiple IMSIs that it will switch between depending on what country the device is deployed in or whether or not it has been able to connect. To ensure that you can connect with any of the IMSIs used, please add all of the following APN and MCC-MNC combinations:

MCC MNC APN
232 10 super
234 10 super
234 50 super
732 123 super

Depending on which country you're connecting from, different IMSIs on the Super SIM may be used to access the cellular networks. For some IMSI's, iOS (particularly on iPhones) may prevent you from changing from the APN. If you cannot change the APN to super you will not be able to use data.

Tools like Apple Configurator can help you get around this limitation if iOS is preventing you from setting the APN.

It depends on which version of iOS your device has.

iOS < 11.3
  1. If Language setting is English (US/Canada), then go to Settings > Cellular > Cellular Data Options > Cellular Network.
  2. If Language setting is English (UK), then go to Settings > Mobile Data > Mobile Data Options > Mobile Data Network.
  3. For other languages, use the appropriate menu path.
  4. Tap APN and enter super for Cellular/Mobile Data and LTE
  5. Leave blank the Username and Password fields.

iOS ≥ 11.3

  1. If Language setting is English (US/Canada), then go to Settings > Cellular > Cellular Data Options > Cellular Data Network.
  2. If Language setting is English (UK), then go to Settings > Mobile Data > Mobile Data Options > Mobile Data Network.
  3. For other languages, use the appropriate menu path.
  4. Tap APN and enter super under both Cellular/Mobile Data and LTE.
  5. Leave blank the Username and Password fields.

iOS ≥ 12

  1. If Language setting is English (US/Canada), then go to Settings > Cellular > Cellular Data Network.
  2. If Language setting is English (UK), then go to Settings > Mobile Data > Mobile Data Network.
  3. For other languages, use the appropriate menu path.
  4. Tap APN and enter super.
  5. Leave blank the Username and Password fields.

You can find more information about viewing and editing APNs in iPhones and iPads on this Apple support page.

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.
