O2 mobile broadband SIM only

O2 mobile broadband SIMs are data-only SIMs designed for MiFi units, 4G and 5G routers, USB dongles and tablets rather than phones.

They're a handy way to get online when you're away from home, set up a portable Wi-Fi hotspot, or connect a laptop on the move.

It can, especially in areas with strong O2 4G or 5G coverage. Popped into a router, a data-only SIM lets several devices share the connection without a fixed-line installation.

For everyday browsing and streaming choose a large or unlimited data allowance, and check O2's coverage and typical speeds at your address before relying on it.
