Good to know
Good to Know
- Full-fibre (FTTP) is available to 78% of UK premises; entry-tier 100–150 Mbps plans cost £22–£32/month, often competitive with or cheaper than older FTTC technology.
- London has excellent mobile coverage; expect mean 5G speeds of 120–180 Mbps in central areas. EE offers the fastest average 4G/5G speeds; Three offers best value; all four networks exceed 99% 4G coverage.
- SIM-only plans are far cheaper than bundled handset deals—budget MVNOs (iD Mobile, Giffgaff, VOXI) often save £130–350/year compared to major operators.
- Most UK networks apply annual mid-contract price rises (typically £2–3.50/month in April); check terms before signing. Some smaller providers (Smarty, VOXI, spusu) offer no mid-contract rises.
- e-SIM adoption is high; most modern devices support it. Tourist e-SIM data plans range £1–4 USD for short stays and offer instant setup without airport SIM card hassle.
- Roaming within EU/Europe: major carriers include EU roaming; budget operators (Lebara, Asda Mobile, Talkmobile) often have free EU roaming on selected plans up to 46–47 destinations.
- London Underground has limited mobile signal; EE has invested most heavily in coverage but service remains patchy on some lines—use WiFi where available.
