SIM Hosting

Send SMS and run USSD flows through real, physical SIM cards.

Pair an Android phone holding real SIM cards, define named Services for SMS or USSD, then trigger them from your own external site or automatically from a VTU platform built on Xpiriatech.

Real physical SIM cards, not virtual numbers
SMS and multi-step USSD services
Trigger by public REST API
Auto-wire to VTU network top-ups
Signed webhooks or job polling for results
Actively expanding verified carrier coverage

What's Included

Everything you need, nothing you don't.

Pair Real Devices

Pair an Android phone running the Xpiriatech SIM Host app with a 15-minute code — it reports each SIM slot’s carrier and number once online.

SMS & USSD Services

Define reusable Services — a plain SMS, or a multi-step USSD walkthrough — with {{VARIABLE}} placeholders like phone number or amount.

Trigger by API or Auto-Wire

Call a Service from your own site via a public REST API with an API key, or wire it directly to a VTU project’s Networks for automatic top-ups.

Job Tracking

Poll a job’s status or receive a signed webhook (HMAC-SHA256, retried automatically) when it completes, fails or times out.

Who Is This For

VTU Platform Automation

Deliver airtime, data or other top-ups over real USSD instead of a paid vending API, wired directly to your Xpiriatech VTU project.

Custom Site Notifications

Trigger SMS from your own external application through a real SIM card, without a third-party SMS gateway.
