The global IoT SIM card you actually control

Connect IoT and M2M devices across 680+ networks in 180+ countries with one non-steered global IoT SIM. Supports 2G, 3G, 4G, LTE-M, and NB-IoT on SGP.02 and SGP.32 standards with the signal quality, visibility, and freedom no other SIM will give you.

Global Coverage

Connect on the best network in every market

There are no contracts or agreements holding you back here. Our SIMs are non-steered and they’re global, meaning a device attaches to the strongest signal available wherever it sits, not the one a traditional carrier would prefer.

View coverage in your region like Europe, APAC, North America, Latin America, and MENA.

Why it wins at scale

Why teams running global fleets choose Onomondo

A global IoT SIM has one job: keep your devices connected wherever they go, for as long as they’re in the field.

Expand without new contracts
Enter a new market by shipping the same SIM with the same SKU for every device. No more local negotiations, no new supply chains to manage.
Best signal, everywhere
Non-steered selection means fewer dead zones and faster registration, wherever a device travels.
Control cost and behavior
The bill tracks what your fleet actually uses. Build network lists by signal quality or by cost, set cost alerts, and with Magic Mode pay only for SIMs that actually transmit.
Own your SIMs, leave anytime
You own every SIM and its keys. If you ever leave, switch over the air to any GSMA-certified operator, with no exit penalty.
One profile, one SKU, one APN
One configuration ships to every market, so engineering stops maintaining regional variants.
Out of the box connectivity
Off the manufacturing line or delivered to your front door, all SIMs come with Onomondo connectivity ready to connect.

It’s infrastructure, not resale

Most providers resell another operator’s carrier deal. We built and run our own core network, which is what lets us give you the control, visibility, and freedom on this page.

Control your costs

Cost that tracks usage, not surprises

You pay for the data your devices use and the devices that are on. Everything else stays off the bill.

Pay only for active data

Usage-based and per MB. No bundles to pre-buy, no minimums to hit.

Idle devices cost nothing

Billing pauses automatically on inactive SIMs, so warehouse stock never accrues cost.

No roaming surcharges

One rate structure across every network you reach. Nothing per-country to reconcile.

Limits before, not after

Set data and cost limits, with alerts before a threshold instead of a bill after it.
No lock-in
You have the freedom to leave

You own every SIM and its keys. No lock-in periods, no exit penalties, no migration you have to negotiate for months. If we stop earning your business, you switch operators over the air, without recalling a single device.

  • You own your SIMs and your keys
  • Switch operators over the air, no site visits
  • Understand your options
  • Move to any GSMA-certified operator

“With Onomondo, we can change things remotely and lower the cost of roaming. Without it, we would have stopped at ‘the container is on the ship’. Now we understand what happens inside the container.”
