It's now as easy as sending a text message to change networks.

Gone are the days of having to phone your mobile network, navigate the menu options and then sit on hold to switch to a different mobile network and a better deal.  New rules brought in by Ofcom back in 2019 mean you can now just send a text message.

The text service is supported by all UK mobile networks and is useful for two scenarios:

  1. Requesting your PAC code to keep your existing phone number and take it to a new network provider
  2. Finding out how much it's going to cost you if you end your contract early and switch to another network

What is a PAC Code?

A PAC code is a ‘Porting Authorisation Code’ – a nine-digit code that allows you to move your mobile phone number to another mobile network. It's the code you'll need if you're changing network but don’t want to change your phone number.

Once you’ve got your PAC code from your current network you give it to the network you’re moving to (usually by filling in an online form) and they handle the entire process for you – telling your old network to move your existing number over to your new network, usually within 24 hours.

How to get a PAC code from any network via text message

Getting a PAC code from your current network to switch to a new network is really easy. Since July 2019, all you have to do is text the word PAC to 65075, from the phone that is using the mobile number that you want to keep.

Occasionally you may need to provide additional information along with the word ‘PAC’, such as your date of birth but send the first text and the network will reply with the next steps if they need more info.

Requesting your PAC code via text is free, you’ll get a reply pretty much immediately.  With your PAC, the network will usually include some additional important info, such as whether you’ll have to pay a charge to change network (e.g. if you're ending your contract early).

Whilst this is the easiest and fastest way to request a PAC code, many networks have other methods available too which are listed below.

Whatever the method of requesting the code, do it before your close your account with the current network. The code lasts 30 days, so if you don’t give it to your new network within that window you'll need to request another one.

Also make sure you’re out of contract when you switch, otherwise you may have to pay an early cancellation fee.  You may find the new deal you've found is so good that this is cancellation fee is worth paying but make sure you know how much you'll have to pay.

What to do with my PAC code

Once you have your PAC code from your old network, you need to give it to your new network.

Firstly, you need a new network - if you buy a new phone contract or SIM only plan from Chitter Chatter, you'll have the option to enter your PAC code at checkout so we can port the number over for you to your new network.

You'll be issued with a temporary number for your new network whilst your current phone number is ported over.

Alternatively, wait until you receive your new phone and SIM and then give your PAC code to your new network. You can usually do this on their website.
