Independent comparison
Compare SIM-only plans around how you actually use a phone
Build a useful SIM-only shortlist from data use, local coverage, contract flexibility, roaming and handset compatibility.
Start with the shape of the decision
The cheapest-looking SIM is not a match if its network is unreliable where the phone is used or its allowance does not fit real behaviour. Define those needs first so future plan results can be filtered rather than presented as an arbitrary ranking.
Free checks first
- Check several recent bills or the handset settings for typical data use.
- List the places where dependable calls and data matter most.
- Confirm whether the current handset is unlocked and still receiving required software support.
