When you compare mobile phones you'll notice some handsets are locked to a certain network. If you come across a deal that works really well for you, but requires you to change networks, you may want to keep your current number when switching.
Likewise, if you have a number you use for a personal business or enterprise, and your customers know your number well already, you might want to keep the same number to save hassle changing it on many platforms.
In any case, to keep your current number and move to a new network provider, you're going to need a PAC code.
What is a PAC code?
PAC stands for Porting Authorisation Code. It's a 9 digit alphanumeric code, consisting of 3 letters followed by 6 numbers in the format ABC-123456, which you'll need to switch your number between networks.
You'll only require it if you want to keep your old number, otherwise you can join a new network easily and be given a new number. If you are just looking to switch networks, and don't mind about keeping your number, you probably need to request a STAC code. This will allow you to simply terminate your old number, and your new provider will give you a new number with your SIM or phone purchase.
Your PAC code can be obtained by texting your network or in some cases by phoning them. You may need to provide some information, like your date of birth, in order to process the request.
But how do you go about getting a PAC code from your network, to start the process of switching?
How to get a PAC code
As of 2019, thanks to new guidance by OFCOM, getting hold of your PAC code is very simple. Before this your network was quite likely to attempt to persuade you to stay with them, using their powers of persuasion.
These tactics could dissuade customers from calling up in the first place, and OFCOM, the governing standards body, received a large number of complaints about the process. Many of these complaints were regarding the long time it took to change providers, with some citing the difficulty of contacting multiple providers just to get through the process as a demotivating factor.
In 2019 OFCOM ruled that providers were obligated to provide a PAC code to any customer who requested one, and put a system in place to request by text. For all UK network providers, the text-to-switch system allows customers to text PAC to 65075, and in return receive a code within 1 minute.
This code is valid for 30 days and can be sent to your new provider in order to begin the switching process. Once the process is complete, which usually takes 1 working day; you can simply restart your phone to jump to your new network.
The text the network sends containing the PAC code must also stipulate any charges or outstanding payments you need to make to your old network. Therefore it is a good idea to make sure you're paid up and finished with any existing contract before searching for new mobile phone deals, or at least before you request your PAC code.
There are some alternative ways to obtain a PAC code for specific network providers, if you prefer to request one over the phone or online. Requesting a PAC code over the phone leaves you open to being persuaded to stay by your current network. While many consumers consider this annoying, it's important to note that you could be offered a better deal by your current network, potentially even better than any deal you could get from a new provider.

How long does it take to transfer a number to a new phone?
Transferring your number to a new phone usually takes place 1 working day after submitting your PAC code. The exception to this rule is in the instance you submit the PAC code after the daily cut off limit, in which case the transfer will take place 2 working days later. In practice this means that if a network's daily cut off limit is 5pm, submitting your PAC code at 6pm on a Tuesday will mean your transfer will go through 1 working day later than Wednesday, the day the code will be received by your provider.
Transfers will only take place on working days, so if your transfer is taking longer than expected, it could be because it's a weekend or bank holiday.
How do I transfer my contacts to a new phone?
To transfer your contacts, you'll need to work out if they're saved to your SIM card. The simple way to check if this is the case is to take your SIM out. If you're still able to see your contacts on your phone, that means they're saved to your phone rather than your SIM. If they've gone, they are saved on the SIM.
If your contacts are saved to your phone you have two options. If you plan to keep the phone and just put a new SIM into it, no worries, your contacts will be right where you left them,
If you're getting a new phone, you'll need to back up the contacts to an external memory source. For iPhones this could be the iCloud or by backing up on iTunes. Alternatively for Androids you could use Google Drive or a Micro SD card.
If your contacts are saved on your SIM, you'll need to import them to your new phone or your current phone if you're keeping it. This can usually be done through the settings section of your handset. Look for an option saying “Import contacts” or “Copy contacts”.
