Can I get a giffgaff SIM if I have a bad credit rating?

Yes, giffgaff SIMs are contract free, meaning they are ideal for those with bad credit ratings.

Do I need to unlock my phone to use a giffgaff SIM?

If you bought your phone from giffgaff, or it originally came with a giffgaff SIM, then you shouldn’t need to unlock your phone in order to use a giffgaff SIM.

Since December 2021, it is illegal for any network to sell a mobile phone that is locked to a specific network.

If you bought your phone before this date, it may be locked to your current network. If you’re unsure if your phone is unlocked, simply insert a SIM from a different network - if your phone is locked, an error message will be shown.

All providers must unlock your phone for free. You will need to contact your current network to do this. They will ask for your IMEI number, which you can obtain by dialling *#06# from your phone.

What size SIM cards can I get with giffgaff?

  1. Standard - the largest SIM card size, which is generally used with older non-smartphones. Newer phones are likely to use micro or nano SIMs.

  2. Micro - Once considered a smaller replacement for standard SIMs, micro SIMs are less prevalent today, being replaced by the even smaller nano SIM. Older smartphones or budget phones may still use a micro SIM.

  3. Nano - The smallest and most common SIM card size used in phones sold today. Used by the newer iPhones and Samsungs.

Can I switch from my current network to a giffgaff SIM?

Yes, it’s easy to switch to giffgaff. From your current network, text PAC to 65075 for free. You will receive a reply text within 5 minutes, which will contain your PAC code.

You will need to give this PAC code to giffgaff. You can do this at the time of purchase, or by contacting giffgaff after you have received your giffgaff SIM card.

After you have given your PAC code to giffgaff, they will begin the switch on your behalf, which normally takes 3 working days. Once the switch has completed, you will lose signal with your current network. When this happens, you can insert your giffgaff SIM to complete the switching process.
