If your current phone still performs well, there may be little reason to replace it.

SIM-only providers often include larger data allowances for the monthly price.
Benefits Of Phone Contracts

Lower Upfront Costs
Instead of paying hundreds of pounds upfront, the cost is spread over monthly payments.

Many consumers choose a new handset when their contract ends.

Everything is included in one monthly payment.
