Best SIM Card for Visitors to the UK
The UK has fast networks and cheap prepaid plans, but coverage varies sharply outside cities.
- Three and EE lead on 5G coverage
- Prepaid plans start around $12 for 20 GB
- Airport vending machines charge a premium
- Most plans include EU roaming for free
EE is the safest pick for rural areas, while Three offers the best value for heavy data users.
Both networks throttle after a daily cap on cheaper plans, so heavy streamers should pick the higher tier.
