Port your number = Switch for best deals!

Most people switch their mobile number between their two favourite networks every time their contract expires.

This allows you to take advantage of 'new' customer deals which are far more affordable than paying upgrade prices.

Porting your number is easy, you simply order your new phone on a different network, make sure you're happy with it and then call your existing network and ask for your PAC code.

You then give this to your new network who will transfer your number across for you within 24 hours.

Upgrade = Same number, same network

If you are in an area where coverage is an issue or have other reasons to want to stay with your existing network then unfortunately upgrading is one of few options available if you want to keep your number and get a new phone.

To upgrade you simply choose the network logo from our filters, ie: EE Upgrade, O2 Upgrade or Vodafone Upgrade


to see all available upgrade prices for your chosen phone.

You'll be asked by the retailer during checkout for your existing number which will be transferred to your new phone.
