Travel tips
United Kingdom connectivity tips
- London Underground stations often have patchy signal — download offline maps before you go underground.
- Contactless payments work widely; keep a small data buffer for train tickets and TfL apps.
- Scotland and Wales rural routes can be weaker than city LTE/5G — plan offline navigation for long drives.
How much data: A long weekend in London is often fine on 1–3 GB. Multi-city UK trips with heavy Instagram use usually sit happier at 5–10 GB.
