FAQs

Multi Network SIM, answered

How many networks does a multi-network SIM access?

Our UK multi-network SIM delivers access to the Vodafone, Three, O2 and EE mobile networks, automatically connecting to whichever has the strongest signal.

What is an un-steered SIM?

An un-steered SIM connects to whichever network gives the best signal in your location, rather than being locked to one preferred provider — protecting you against network outages.

Are there different tariffs for different countries?

Yes — tariffs are split by zone and territory, so the fewer territories you need coverage in, the cheaper the package. You only pay for what you need.

Can I use a static IP address?

Yes, our multi-network SIM supports both fixed and dynamic IP addresses. For an "on-net" solution, we can also offer private APNs with your own IP addressing.

What is a steered SIM, and why does it matter?

A steered SIM typically only allows access to a single, preferred network provider. Our un-steered SIM instead prioritises whichever network gives you the best available connection.
