Switching SIM Only
When can I switch to a Sim only deals?
First, check whether you are still under contract with your current provider. When you have reached the end of your contract you are free to switch suppliers and the phone is usually yours. If you're unsure, it's worth checking your contract documents or simply contacting your current provider to find out. If you are still in contract you can still switch but there are likely to be termination charges.
Once you have selected your new SIM only deal you will need to get in touch with your current network to cancel your contract
Can I keep my number if switching provider?
If you want to keep your number you'll need to get a PAC code (Porting Authorisation Code – its usually three letters and six numbers) from your existing provider. It’s free, it’s easy and lots of people do it. Just call them up and ask for your PAC.
You may also be able to get your PAC code online via web chats, email or even in the post. Ofcom says that your provider must give you your PAC code when you request it and that it has to be issued to you immediately over the phone or within two hours in a text message so you should have no problem.
Once you have it, you've now got 30 days to give the PAC code to your new network otherwise it'll expire. Your new network will take the PAC code and sort things out with your existing network, letting them know that there's a request to retain your mobile phone number. Your number could be transferred to your new network's SIM card as early as the next working day, but don't be surprised if it takes a little bit longer.
How to Save money on your SIM
What do I do with my old Sim card?
If you wish to dispose of an old SIM card you should always damage the SIM before disposal. The safest thing to do is cut the SIM card up using scissors, making sure to damage the bronze foil area of the chip, this is where the data is stored.
