Choosing an IoT Connectivity Provider: 10 Questions to Ask
Choosing an IoT connectivity provider is one of the highest-leverage decisions in any connected-product project. Get it right and your devices simply work, your bills are predictable and you can scale without friction. Get it wrong and you inherit coverage gaps, surprise charges and operational pain that firmware updates cannot fix. Here are the ten questions that separate a great provider from a risky one.
1. How many networks are behind the SIM?
Coverage is everything in IoT. Ask how many operators and countries a single SIM reaches, and whether it is built on tier-1 networks. A genuine multi-network IoT SIM that roams across hundreds of networks gives you resilience and one global SKU; a single-operator SIM does not.
2. How do you handle permanent roaming?
If your devices live abroad, this is critical. A serious provider will explain how they manage permanent roaming — local profiles, eSIM localisation, operator relationships — so your fleet is not throttled or disconnected. A vague answer here is a red flag.
3. What radio technologies are supported?
Confirm support for LTE-M, NB-IoT, 4G and 5G, and a clear plan for 2G/3G sunset. The right technology mix affects battery life, coverage and longevity. (For the basics, see what IoT connectivity is.)
4. How good is the management platform?
You will live in this platform daily. Can you activate, suspend, steer and monitor SIMs, set bundles and limits, and diagnose problems without a support ticket for every action? Extrafon’s Assets Management Platform does all of this from one login, with reselling and multi-tenant roles built in.
5. Are there real APIs?
If you are building a product, you will want to embed provisioning, billing and management into your own systems. Ask for API documentation and whether the provider can support integration — something our development team does routinely.
6. What security controls are available?
Look for IMEI binding, per-SIM usage limits, destination restrictions, encryption and anomaly monitoring. These are the controls in our IoT SIM security guide — if a provider cannot offer them, your fleet is exposed.
7. How transparent is pricing?
Understand the SIM fee, activation, monthly per-SIM charge and data/SMS rates, plus any roaming or minimum-usage terms. Because Extrafon resells tier-1 operators built on 20+ years of relationships, the underlying cost is sharpened and passed on — best price, guaranteed.
8. Prepaid, postpaid or both?
Flexible commercial models matter. Prepaid pay-as-you-go suits pilots and unpredictable fleets; defined bundles suit stable usage. The ability to mix and switch — covered in prepaid vs postpaid for business — can cut your bill without changing a line of code.
9. Can it scale — and wholesale?
Ask whether the same SIM and platform serve a pilot of ten and a rollout of millions, and whether wholesale and routing options exist for high volumes. You want a partner you will not outgrow.
10. Who actually answers the phone?
When a device goes quiet at 2am, support matters. Look for a provider with real engineering depth and a single point of contact — not a faceless portal. Swiss-based and operator-grade is a good sign.
Putting it together
The best provider is not simply the cheapest line on a quote. It is the one whose networks, platform, security, pricing and people remove risk from your roadmap. Score each candidate against these ten questions and the right partner usually becomes obvious. Whether you are running M2M or IoT, the goal is the same: connectivity that you never have to think about.
