Twilio Super Sim – Public Beta

That's what a virtual private network is - an overlay on transport networks to allow a group of devices under the same ownership to communicate. While VPNs are often used to cloak IP addresses, they were originally a corporate thing. Your in-house net could be transported over the public Internet while keeping its in-house address space and some degree of privacy.

These are just self-service pricing options to get people started on Day 1.

When we price custom for enterprise (i.e. specific countries, carriers, roll-out plan), the pricing becomes a lot more flexible. Should be seeing updates to that messaging soon.

Hi there, Matt Jackson from Twilio here. I’m the Product Manager for Super SIM. You’re right, we currently don’t have support for Verizon but we hope to be able to add it in the future. We understand that different developers have different connectivity preferences, so we designed our system to be flexible to adding new partners to the platform. As we continue to add networks, the networks of the future should become available to Super SIMs bought today.

With Super SIM you can also have access to multiple networks at once. For example, if you’re connected to T-Mobile and move to an area where there isn’t coverage, your device can automatically switch over to AT&T. This gives you redundant connectivity too in case any one network or tower goes down.

This will be an issue, fraud prevention systems targeted at reducing IRFS aren’t exactly a fan of VOIP numbers.

_How does Super SIM compare to Programmable Wireless?_

Super SIM is a separate offering from Programmable Wireless. Our first IoT connectivity solution, Programmable Wireless, was developed in partnership with T-Mobile, allowing us to connect to T-Mobile’s global partner network and run on top of T-Mobile’s mobile core infrastructure. For Super SIM, we developed our own cloud scale mobile core that allows us to connect with multiple partners, offering a comprehensive, guaranteed list of tier-1 networks for your devices to connect to. Moreover, with Super SIM, we’re able to extend control to you as the developer by letting you choose which networks your Super SIMs can and cannot connect to. This is really important for IoT use cases where your hardware may not be compatible with all of the networks that are available in a country. While we offer a lot of our networks at the same price, there are some that may be more costly but can offer you more redundant coverage or coverage in more remote regions. You can choose which networks work best for your use case and your customers and take control of your connectivity.

_Does Super SIM support voice calling and SMS?_

Super SIM was designed with IoT use cases in mind that primarily use data. You can use our SMS Commands API to send machine-to-machine SMS between your device and your cloud but Super SIM does not support sending or receiving SMS from other phone numbers. Super SIM does not support traditional calling such as with a smartphone’s native dialer.

_Why can’t I send SMS with an arbitrary originator number with Programmable Wireless SIMs? Is this a bug?_

This is the intended behavior. When you send a SMS from a phone’s messaging apps with Programmable Wireless SIMs that message gets handled by Twilio’s Programmable SMS APIs. You cannot set the from number on those messages to a phone number that is not a Twilio phone number that you own. This prevents number spoofing which while it has valid uses, it’s often used for SMS spamming which Twilio takes very seriously so this is a limitation to that feature.
