Frequently Asked Questions
Can I keep my number?
To keep your number when switching to a new contract, text PAC to 65075 from your current SIM to receive a PAC code valid for 30 days. If you enter this code during checkout, your new network will manage the switch. The switch will occur the next working day, automatically ending your old contract.
Check out our Definitive PAC Code Guide for everything you need to know - common mistakes, tips, and FAQs.
How do I order?
After you choose the plan with the features that suit you best, click the "Get Deal" button on the deal card. You'll be transferred to the retailer's website where you can place your order. Any personal details you enter will handled by that retailer and will be processed based on their privacy policy - we don't see or process your data.
As a price comparison service we receive data feeds directly from our partered retailers. We try to ensure all prices and plan benefits are correct, but please check the full details of the deal you add to the basket before ordering as errors in our data feeds may occasionally occur.
To help us continue to provide our free service we may earn a commission from our partners if you make a purchase. This doesn't affect the price you pay or the ranking order of our comparison results.
