Why keep your UK number?

Many people want to hold on to their UK number after returning home. Common reasons include:

  • check_circleContinuing to receive notifications and texts from UK banks, universities, landlords, and government bodies.
  • check_circleLogging in to UK accounts and services that were registered with the UK number.
  • check_circlePlanning to return to the UK in the future — keeping the number saves the hassle of getting a new one.
  • check_circleUsing the UK number as a long-term contact for friends and classmates in the UK.

The expiry rule: unused for roughly 6 months and the number is suspended

There is just one rule to remember for keeping your giffgaff number active:

lightbulb
Make at least one active use of the SIM within roughly every six months (around 180 days) — an outgoing call, text, or MMS to another number, or a session on giffgaff mobile data — and your number stays active indefinitely. giffgaff will normally send an email reminder when expiry is approaching. In other words, one call, text, or data session every six months is all it takes.

What counts as 'active use'?

giffgaff officially recognises three categories of activity. Do any one of them within roughly every six months:

  • check_circle✅ Make an outgoing call, send a text, or send an MMS to another number — the most direct option (calls to emergency numbers 999/112, giffgaff member services, or 0800 freephone numbers do not count).
  • check_circle✅ Use giffgaff mobile data to browse the internet at least once — a data session counts as active use.
  • check_circle✅ Purchase credit (top-up balance) or a plan.
  • check_circle⚠️ Connecting to Wi-Fi only, without using giffgaff mobile data — this has nothing to do with your SIM and does not count.
  • check_circle⚠️ Only receiving incoming calls or texts, with the card inserted but no outgoing action — this is not reliable; do not rely on it to keep your number.

Any one category is enough, and you do not need to keep buying a plan. Keep a little credit and complete an outgoing call or text, or a mobile-data connection. The action is charged at the PAYG or roaming rate that applies at the time.

The easiest way to keep your number

  1. 1

    Set a recurring reminder every five months

    Add a repeating calendar event roughly every five months — slightly ahead of the six-month limit — so you never cut it too close.
  2. 2

    Keep a small balance in your account

    You don't need to maintain an active plan. Just make sure there's a small credit balance so you can complete a call or text when the reminder goes off.
  3. 3

    Take action when the reminder fires

    When the reminder comes up, use the UK SIM to send a text, make a call, or connect to mobile data. You can insert the card into an old phone or a dual-SIM handset and do it in under a minute.
  4. 4

    Confirm the action went through

    Once the text is sent or the call connects, you're set for another six months. Wait for the next reminder, then repeat.

Turning 'use it once every six months' into a fixed calendar reminder is the most reliable and effortless way to keep your number. Twice a year, one minute each time.

Prefer not to work out the date yourself? Open the free giffgaff keep-number calculator to estimate your next action date and add a calendar reminder.

What to do if your number is close to expiry or already suspended

  • check_circleApproaching expiry: giffgaff typically sends two warning emails (roughly one month before suspension, then again roughly five days before). Simply make one active use — send a text, make a call, or use mobile data — and the clock resets.
  • check_circleAlready suspended: within 30 days of suspension you can contact giffgaff support to request a PAC code and port the number to another UK network to preserve it.
  • check_circleMore than 30 days since suspension: the number is recycled and cannot be recovered. You would need to get a new SIM and a new number.
lightbulb
The best approach is to never let it get suspended in the first place. A regular six-monthly habit is far less stressful than trying to rescue a suspended number. Always refer to giffgaff's official email notifications and account alerts for the exact deadlines.

Keeping vs porting your number (PAC code): what's the difference?

These two terms are sometimes confused. A quick summary:

  • check_circleKeeping your number: your number stays on giffgaff. As long as you follow the usage rule, no network change is needed.
  • check_circlePorting your number (PAC code): you transfer your UK number to a different UK network while keeping the same number. Typically used when a number is about to be or has already been suspended, or when you want to switch providers without losing the number.

Frequently asked questions

How long before a giffgaff number expires from non-use?expand_more
Typically about six months (around 180 days) of complete inactivity. giffgaff generally sends two warning emails: one roughly a month before suspension and another roughly five days before. Taking any active action in response to either reminder will reset the clock.
Which actions keep the number active?expand_more
Any one of the following, completed within roughly every six months: ① Make an outgoing call, send a text, or send an MMS to another number (calls to emergency services, giffgaff member services, or freephone numbers do not count); ② Use giffgaff mobile data at least once; ③ Purchase credit or a plan. You do not need to maintain a plan, but calls, texts and data are charged at the applicable rate. Receiving only, or connecting to Wi-Fi only, does not count.
Can I keep my UK number after I've returned home?expand_more
Yes. As long as you make one active use within roughly every six months, the number stays active regardless of where you are. Insert the SIM into an old phone or a dual-SIM handset from time to time, set a six-monthly reminder, and you're all set.
Can a suspended number be recovered?expand_more
Within 30 days of suspension, you can contact giffgaff support to request a PAC code and port the number to another UK network to preserve it. After 30 days the number is recycled permanently and cannot be retrieved — you would need a new SIM and a new number.
Do I need to keep buying a plan to hold on to the number?expand_more
No. You do not need to maintain an active plan. One active use every few months is sufficient — a text, a call, or a mobile data session all count. There is no need to renew a plan, but it is wise to keep a small credit balance in your account so you can send a text or make a call whenever the reminder goes off.
