Super SIM

Super SIM is a global cellular connectivity platform to connect your IoT devices around the world. With a Super SIM in your device you’ll be able to connect to the most comprehensive list of Tier 1 global networks available via a single SIM. Powered by Twilio’s own cloud-scale mobile core, you have the freedom to choose your networks, so you can optimize for coverage, performance, and price. Use highly available APIs to program your connectivity operations, from changing SIM status and tracking data consumption, to sending machine-to-machine messages to devices.

Super SIM supports 2G (GSM/GPRS), 3G (UMTS/CDMA2000), 4G (LTE), and LTE-M connections.

General availability

Super SIM is now generally available. This applies to the API resources used for managing your Super SIM’s lifecycle (Sims, Fleets, Network Access Profiles, and Networks) and data connectivity using the super APN, traffic from which breaks out to the Internet via the Twilio Mobile Core in Ashburn, USA.

All other resources within the Super SIM API, and Internet breakouts outside of the United States, such as Frankfurt, Germany or Singapore, are still in Pilot or Beta. They are therefore not covered by a Twilio SLA. To learn more about pilot and beta product support, please see this Help Center page.

Available networks

Super SIM gives your IoT devices access to nearly 400 cellular networks around the world. Check out Super SIM’s available networks.

Pricing and billing

To use Super SIM, there is a one-time fee for SIM hardware, a monthly subscription fee for active Super SIMs, and usage fees that are charged on a pay-as-you-go basis. Volume pricing is available if you talk to sales.

• One-time SIM fee — SIM hardware starts at $3. You can order multi-size (2FF/3FF/4FF) SIM cards or solderable embedded SIMs (MFF2) from the Console. If you need larger quantities than can be purchased in Console, talk to sales.
• Active SIM Subscription Fee — Starting at $2 per active Super SIM per month. You can set a Super SIM to inactive at any time to stop this recurring fee if you don’t need to use that SIM. You can reactivate at it any time. Learn more about Super SIM states.
• Data Usage — Starting at $0.10 per MB. Data usage is billed on a pay-as-you-go basis. Data usage is billed per byte — no rounding or breakage.
• SMS Commands — Starting at $0.05 per SMS Command sent from your device and $0.01 per SMS Command sent to your device. Use SMS Commands to send machine-to-machine (M2M) SMS to and from your devices.
• Network Access Fees — For some networks, an additional monthly will be charged for each SIM that connects to and uses the network.

Subscription Fee Billing and Data Limit Period

Each Super SIM has its own billing and data-usage cycle: the period is a full month beginning on the day the SIM becomes active. So if a Super SIM is activated on February 14th, its first cycle completes on March 14th, the second on April 14th, and so on.

As each new period begins, payment of the active SIM subscription fee is triggered and the period’s count of bytes transferred starts at zero. If this count reaches the SIM’s applied data limit, data transfer is suspended until the start of the next period. The SIM’s data limit is set in the Fleet the SIM’s Sim resource has been assigned to

If the SIM is inactive at the end of the current billing period, no subscription fee will be charged until the SIM is put back into the active state, at which point a whole new monthly billing and data-usage period starts at the date of re-activation. You can check a SIM’s state by reading its Sim resource’s status value.

Network Access Fees

Some networks offered by Super SIM have a network access fee that is charged if any data or SMS is exchanged over the network. When usage on the network occurs, you will be charged the monthly network access fee. That network access will be good for a full month beginning from when the usage occurred. For example, if you were charged an access fee for a network on February 16th, you won't be charged another access fee for using that same network again until March 16th. If a SIM connects to multiple networks with network access fees, each will have it's own date afterwhich you may be charged another network access fee if you continue to use it.

All data and SMS usage on the network will be charged on a pay-as-you-go basis like on any other offered network. The period between your network access fee charges is independent from the SIM's active subscription fee.
