Why traditional IoT SIMs break at scale
Traditional IoT SIM cards lock you into a single carrier per region. The moment your devices ship internationally, you are signing 12 contracts, managing 12 invoices, and watching connectivity fail wherever the chosen carrier has weak coverage.
Roaming SIMs were supposed to fix this. They do not. Most roaming IoT SIMs route through a single home network and then rely on bilateral agreements that go down without warning. When a device cannot connect, you cannot tell whether it is a signal issue, a carrier outage, or a billing failure.
You need cellular connectivity that picks the best available network for each device, in real time, anywhere in the world. That is what Firsty does.
How Firsty solves it
Multi-MNO routing per session
Each device evaluates available networks and connects to the strongest one available, not a hard-coded home network.
One global rate
Same price per MB whether the device is in Berlin, Mumbai, or São Paulo. No per-country pricing tables to manage.
Real-time CDRs
See exactly what each SIM is doing, where, and on which network. Built for fleet ops.
Remote SIM provisioning
Push new profiles or update existing ones over the air. No truck rolls.
