Many promise a single IoT SIM for global connectivity, but few deliver. Whether it’s getting access to multiple tier-1 carriers in a single country, or getting to choose from a picklist of hundreds of networks around the world for your devices to connect to – our “One SIM” promise means a single SKU for all your devices, no matter where they get deployed.

A single SIM with a Multi-IMSI architecture means virtually no downtime for you. Should a local network fail, our SIM automatically fails over to another available network. This requires no setup and no intervention on your part. With one SIM from Twilio, your devices will stay  connected period. 

Don’t underestimate the power of APIs. Only reliable and stress-tested APIs allow you to expand your business at the pace you want. Whether it’s about automatically activating a SIM when your customer completes a sign-up, or automatically suspending a SIM when data usage gets out of control – APIs are your ticket to operational efficiency and control at scale.

A single set of APIs to operationalize your fleet management means a single integration into your business systems, no matter the location of your SIMs. This in turn means less integration effort, less maintenance effort, and a faster time to market as you grow into new regions.

You might be used to paying different bills to different carriers. That doesn’t mean that that’s how it should be. A single bill across all carriers means less time wasted consolidating bills, chasing errors, or integrating multi-carrier billing into your backend systems.

Twilio has a no-shenanigans policy when it comes to pricing. One Bill also means that you will only ever pay for what you used – By-the-byte charges, NO overage fees, NO breakage (expiring funds), NO need for multiple rate plans or tiered pricing, and as many free SIM state changes as you need (incl. suspend).

Twilio has 10+ years of working with carriers, deep relationships with providers around the globe, and a cloud-native distributed deployment of its own mobile network core. Thanks to this, Twilio can offer a global network of networks that give your IoT devices maximum uptime, while appearing as one network with one configuration for your devices.

As new networks get added to our network, or new radio access technologies like 5G are being rolled out around the world, your SIMs will automatically get updated in the field with no downtime, thanks to our reliable Over-The-Air (OTA) update capabilities. Rest assured that your oldest SIMs in your fleet will always be as up-to-date as the most recently shipped ones.

While some may give you access to many cellular networks with simplified management, One Experience means a single pane of glass to manage your entire fleet of connected SIMs. One login, one place to look, one usage report, one view of everything. That’s the Power of One.

And Twilio offers more than just connectivity. Whether your device needs embedded voice or video, or sensor readings should trigger an SMS or a phone call – Twilio can be your one-stop-shop for all things connectivity and communications. A single web administrative experience across our entire product portfolio means simplified management and operations and whole less hassle.
