Global multi-carrier IoT connectivity plans

Yes. There are several providers offering global IoT connectivity through a single SIM/eSIM that can use multiple mobile carriers, rather than tying your devices to one MNO.

Current industry research also identifies 1NCE, emnify, KORE, Soracom-KDDI, Wireless Logic, AT&T, Verizon, Orange Business, Deutsche Telekom, Vodafone, Telefónica, Telenor and others as major managed IoT connectivity providers.www.gartner.com

My shortlist

For the broadest carrier diversity:
Wireless Logic and KORE stand out. Wireless Logic says it provides access to 750+ networks across 190 countries, while KORE advertises 500+ networks/202 countries for its OmniSIM offering.wirelesslogic.com

For a straightforward developer/API experience:
Soracom or emnify. Soracom supports one SIM across 200+ countries/territories with automatic selection of the strongest available network; emnify describes access to 540+ networks in 180+ countries with multi-IMSI.soracom.io+1

For inexpensive, predictable sensor connectivity:
1NCE is particularly interesting. Its standard plan is currently $14 one-time for up to 10 years, including 500 MB and 250 SMS, with coverage in 170+ countries.www.1nce.com

One important distinction

"Global" doesn't necessarily mean the same thing across providers. There are three models:

1. Global roaming SIM — one SIM roams onto partner carriers.
2. Multi-IMSI/eSIM — the SIM can use different subscriber identities/carrier profiles and switch networks.
3. Local connectivity + global orchestration — the provider can move a device onto a local operator where permanent roaming isn't permitted.

For a mission-critical global deployment, I'd favor #2/#3 over a simple roaming SIM. Permanent-roaming restrictions in some countries can otherwise become a significant issue; providers such as emnify, KORE and Wireless Logic specifically address this with multi-IMSI/eSIM and local profiles.www.emnify.com

If you tell me your expected monthly data/device, number of devices, countries, and whether you need LTE-M/NB-IoT/4G/5G, I can narrow this to the 3 best plans and compare their actual pricing and carrier coverage.

If you need IoT data plans that work across countries and can switch between different cellular carriers, look for global multi-carrier IoT SIMs or multi-IMSI/eUICC eSIM plans. These let a device use one SIM or embedded SIM to access multiple mobile networks, helping maintain connectivity when traveling internationally or when one carrier has poor coverage.

Here are some providers worth comparing, depending on whether you’re connecting GPS trackers, remote sensors, industrial equipment, vehicles, or other IoT devices.

Best international multi-carrier IoT providers

4. 1NCE

Provides IoT connectivity in 170+ countries and regions, with a published lifetime connectivity offering advertised at $14 for 10 years. Its Industrial SIM and SIM chip support its “Freedom to Switch” eUICC feature; verify that the specific switching behavior you need is supported.www.korewireless.com+8

Best for: low-data sensors, tracking devices and cost-conscious deployments.

Plans and global coverage

Quick comparison

What to check before buying

• Automatic switching vs. profile switching: You want automatic network selection or failover if devices must recover from weak coverage without human intervention. Remote eSIM profile switching is a related but different capability.
• Country-level carrier coverage: Check the actual operators available in every country you need, not just the provider's total country count.
• Radio technology: Verify compatibility with your device's LTE bands and whether it needs LTE-M, NB-IoT, 4G or 5G.
• Data costs: Compare per-MB rates, monthly fees, pooled data, SIM costs and any permanent-roaming restrictions.
• Hardware compatibility: Confirm whether your device supports a physical SIM, soldered eSIM (MFF2), or eUICC remote provisioning.

My starting recommendation: Compare Soracom and KORE Super SIM first if automatic carrier switching is essential. Consider 1NCE if your devices send small amounts of data and low long-term cost is the priority.

Let’s narrow it down

What countries will your IoT devices operate in, and roughly how much data will each device use per month? With those two details, I can narrow this to the most suitable plans and compare pricing and carrier coverage.
