Unlimited-data SIM-only plans: compare beyond the label
Compare unlimited-data SIM-only choices by network fit, traffic terms, tethering, roaming, contract length and total cost.
Start with the shape of the decision
An unlimited-data label does not by itself answer whether a plan suits the phone, location or intended use. Check recent real usage first, then compare coverage, speed-management terms, tethering, roaming and the commitment required.
Free checks first
- Read the phone’s recent mobile-data totals over more than one billing period.
- Check coverage where the phone is used most, including indoors.
- Confirm that the handset supports the network and any required eSIM or physical SIM format.
