What is an IoT SIM card?
A SIM built for machines rather than phones: trackers, meters, charge points, card terminals and routers. It is made for long life in the field, low data use and remote management, and is often called an M2M SIM. Read what to look for in an IoT SIM card.
What is a multi-network SIM?
A SIM that can connect to more than one mobile network. The Simsonic IoT SIM is multi-IMSI: it holds several operator identities and steers to the best available network in each country, falling back automatically if one degrades. Read multi-network SIMs explained.
Does the same IoT SIM work in the UK and abroad?
Yes. One SIM works across 650+ carriers in 190+ countries, so a single SKU covers a UK pilot and an international rollout without regional contracts.
Which SIM form factors are available?
Removable 4FF, solderable MFF2 for harsh environments and eSIM, all managed from the same console and API.
Can I test IoT SIMs before committing?
Yes. Trial subscribers run in your real devices next to your current provider, so you can compare coverage, radio and usage in the console before moving to a full tariff. Comparing providers? See Simsonic vs 1NCE.
