How to choose a SIM only plan
Four things decide which plan suits you: the network, the data allowance, where you travel, and who you call.
- Network Pick the network with the best coverage where you live and work.
- Data 20GB suits light use. Choose 50GB, 80GB or unlimited if you stream, video call or hotspot a laptop.
- Travel Many plans include EU roaming. For wider travel, look at the Three Global Roaming or Global Unlimited Roaming plans.
- Calls to Europe Some O2 and EE plans include calls from the UK to the EU.
