International and Roaming Data SIM Cards for Routers and IoT Devices
Applications that operate across multiple countries – international vehicles and fleets, mobile workers travelling in Europe, IoT devices deployed across multiple countries, or UK businesses with premises overseas – require SIM cards that provide data connectivity beyond the UK network footprint.
SimWise supplies multi-country roaming SIM cards for routers, IoT devices, and mobile applications requiring data connectivity in Europe and globally.
EU Roaming: The Post-Brexit Position
Following the UK's exit from the European Union, the automatic right to use UK consumer SIM cards in the EU at no extra cost (established by the EU Roaming Regulation) no longer applies to UK operators as a legal obligation. In practice, UK operators have largely retained EU roaming as part of premium unlimited tariffs, but roaming charges have been reintroduced on some lower-cost tariffs.
For IoT devices deployed across UK and EU locations, a multi-region IoT SIM that provides native coverage in both UK and EU countries – rather than international roaming on top of a UK SIM – is the more reliable and often more cost-effective approach.
What “Unlimited Roaming” Means in Practice
Truly unlimited, unthrottled data roaming internationally is not commercially available on consumer tariffs. What is available is a generous data roaming allowance – typically 15-25 GB per month on EU roaming on UK unlimited tariffs, or a data pool that works across multiple countries on a dedicated roaming SIM. SimWise will advise on the most appropriate solution for your specific international connectivity requirement.
Applications for International Roaming SIMs
- International fleet and vehicle telematics – HGVs and coaches operating cross-Channel routes or in mainland Europe need connectivity in multiple countries. A roaming IoT SIM provides consistent coverage from Dover to the destination country.
- Mobile workers – staff based in the UK who travel regularly to EU countries benefit from a router SIM or device SIM with included EU data roaming.
- EU IoT deployments – UK businesses with IoT devices installed in EU countries need a SIM that provides coverage in those countries on a managed, cost-controlled basis.
- Events and exhibitions – UK businesses exhibiting at trade shows or events in Europe need temporary connectivity for payment terminals and demonstrations.
