How to cancel giffgaff
Leaving giffgaff is straightforward once you know which route you need. Most customers are on rolling monthly goodybags with no minimum term, so there is usually no early exit fee — you simply stop your plan and move your number elsewhere. The steps below cover how to cancel giffgaff whether you want to keep your mobile number or start fresh.
If you are switching to another network and want to keep the same number, you need a PAC (Porting Authorisation Code). Text PAC to 65075 from your giffgaff phone. giffgaff replies by text with a nine-character code. Give that code to your new provider when you sign up — they handle the transfer. The code is valid for 30 days.
If you do not need your number, text STAC to 75075 instead. giffgaff will confirm when your service ends and the number is disconnected.
You can also use our PAC & STAC code generator to see the exact text message and short code before you send it.
How do I cancel giffgaff if I am on a goodybag?
giffgaff runs on rolling 30-day goodybags rather than long fixed contracts. That means you can cancel my giffgaff at any time without paying an early termination charge on a standard SIM-only plan.
Before you leave, turn off auto-renewal so you are not charged for another goodybag after your switch date:
- Log in at giffgaff.com or open the giffgaff app.
- Go to your goodybag settings and disable auto-renew.
- Request your PAC or STAC code (see above).
- Give the PAC to your new provider — they will arrange the switch and your giffgaff service ends once the port completes.
If you have unused goodybag credit or airtime balance, check giffgaff's terms — remaining credit is typically forfeited when you leave.
How do you cancel giffgaff on a phone bought through giffgaff?
If you bought a handset on a repayment plan through giffgaff, cancelling the SIM does not automatically clear what you owe on the device. You may need to pay off the remaining instalments or return the phone according to giffgaff's terms. Check your account dashboard or contact giffgaff member support before requesting a PAC code.
For a standard SIM-only goodybag with no outstanding device balance, no formal notice letter is required — the PAC/STAC process is enough. If you prefer written confirmation, our cancellation letter generator can draft a letter or email you can send to giffgaff.
How to cancel my giffgaff account completely
A giffgaff account and a giffgaff SIM are linked but not identical. Porting your number away with a PAC code effectively ends your mobile service. Your online account may remain accessible for a period afterwards.
To fully close things down:
- Disable auto-renew on any active goodybag.
- Request a STAC if you are not porting your number and want the line disconnected.
- Remove any saved payment details from your giffgaff account if you do not plan to return.
- Download any bills or usage records you may need before the account becomes inactive.
If giff gaff cancel steps are not working — for example, you no longer have access to the SIM — contact giffgaff member support through their help pages with your account email and registered address.
What happens after you cancel giffgaff?
Once your PAC transfer completes, your giffgaff SIM stops working and your number moves to your new network. The switch usually takes one working day, though it can occasionally take longer at weekends or bank holidays.
During the switch:
- Keep your giffgaff SIM in your phone until the new provider confirms the port is done.
- Do not cancel the PAC request or start a second port — that can delay the process.
- Make sure your new SIM is activated and ready before the port date.
If you used a STAC instead, giffgaff disconnects your number on the date they confirm. You will need a new number from your next provider.
Switching from giffgaff to another network
giffgaff runs on the O2 network, so if coverage or price is the reason you are leaving, you have plenty of alternatives. Popular options include:
- Smarty SIM only deals — low-cost rolling plans on the Three network
- Lebara SIM only deals — flexible plans with international calling included
- iD Mobile deals — budget-friendly plans on the Three network
- EE deals — wide coverage and fast 4G/5G speeds
- Vodafone deals — strong UK coverage with a range of plan lengths
For a broader comparison, browse all SIM only deals or filter to 30-day SIM only deals if you want the same rolling flexibility you had with giffgaff.

Tips before you leave giffgaff
Check your goodybag renewal date. If a new goodybag is about to auto-renew, turn off auto-renew first to avoid paying for a full month you will not use.
Back up your contacts and messages. Once the port completes, anything stored on the SIM or in giffgaff-specific apps may no longer be accessible.
Update two-factor authentication. If any accounts use your giffgaff number for login codes, update them to your new number before or immediately after the switch.
Compare before you commit. giffgaff is often competitive on price, but deals change regularly. Use our cheapest SIM only deals page to check whether another network offers better value for your usage before you port.
