Compare SIM only dealsSIM only or a phone contract?
A SIM only deal gives you minutes, texts and data without a phone. You use it in a phone you already own.
A phone contract includes a handset as well, so the monthly price is higher. That is why this check compares your price with SIM only prices: it shows what the minutes, texts and data typically cost.
When does my phone contract end?
Text INFO to 85075 to find out. The text is free, and the reply tells you whether you're in contract and what fees apply. Your network must also message you 10 to 40 days before your contract ends.
