Buying a phone is a sequence of decisions, not a search for one universal “best” model. Start with the work the phone must do, decide how long you intend to keep it, set a total ownership budget and only then compare models, sellers and payment routes.
Start here: use the Complete Phone Buying Guide for the full process, or choose the decision below that matches your situation.
Choose the phone around your real use
- Set a realistic smartphone budget.
- Choose storage from your current usage.
- Plan the useful life before buying.
- Compare iPhone and Android without relying on brand loyalty.
- Choose for a child, teenager, older person or work use.
Choose when and where to buy

Use the total cost, not the headline
Compare the handset, airtime, mandatory charges, accessories, insurance, likely repairs and expected resale proceeds. Keep provisional cashback and trade-in estimates separate until they are actually earned. A low monthly payment can be a long commitment rather than a cheap phone.
Check the exact device, not just the model family
Storage, region, condition, security-support period and seller can change the value of two phones with the same marketing name. UK manufacturers of applicable consumer connectable products must publish a defined security-support period, so use the exact model’s published commitment rather than assuming every device from one brand receives the same support.
Before paying
- Identify the legal seller and the exact phone variant.
- Save the product page, condition description and promised contents.
- Check returns, warranty and any finance or contract summary.
- For a used phone, verify account locks, identity, condition and functionality.
- Keep proof of payment and the serial or IMEI privately.
