The summary sheet across all nine criteria in the four full reports. Grades are the examiner's judgement of pattern and record, not a snapshot of any single week's testing — follow each report for the working.
| Network | Overall | Best mark | Weakest mark | One-line verdict | Report |
|---|---|---|---|---|---|
| EE | A- | Coverage (A) | Value (C+) | The champion's footprint, at the champion's prices. | Read → |
| O2 | B+ | Roaming (A) | Speed under load (C+) | EU roaming kept, contracts that stop — mind the evening squeeze. | Read → |
| Sky Mobile | B+ | Data rules (A) | Coverage control (B-) | The cleverest retail mechanics in mobile, on rented signal. | Read → |
| Three | B | Value (A) | Roaming (C) | Fastest-tier 5G and the cheapest unlimited; walls and borders cost it. | Read → |
How to use this table honestly
- A league position is a national pattern; your postcode is a sample of one. The coverage check outranks every grade here.
- Weight the criteria by your life: a homeworker weights indoor signal; a traveller weights roaming; a family weights multi-SIM value.
- Audition the winner with one rolling month before any fixed term.
The four, in one sentence each
- EE — buy the coverage record, budget for the premium.
- O2 — buy the roaming and the split contract, trial your evenings first.
- Sky Mobile — buy the reserve, and buy it from inside a Sky household.
- Three — buy the value, after the indoor check passes.
