A Vodafone PAYG number will be deactivated after six months of inactivity. Vodafone sends a text message warning at the 180-day mark, so you do get a heads-up before the number disappears. If your SIM has only been inactive for around three months, reconnection is still likely possible.
According to a widely cited post in the Reddit r/expats community, Vodafone UK deactivates a mobile number once the SIM has been inactive for six months. The 180-day text message warning is your last practical opportunity to act before the number is lost. Miss that window and the number goes, along with any remaining credit on the SIM.
If your SIM has been inactive for around three months, a JustAnswer expert response suggests reconnection is still available. So the closer you are to three months rather than six, the better your chances of getting the number back.
Activity means any of the following:
Simply having the SIM inserted in a phone that is switched on does not count. Vodafone looks for actual network usage, not just the presence of the SIM on the network.
The available evidence points to PAYG (pay-as-you-go) SIMs as the main concern here. Contract customers pay a monthly direct debit, which itself constitutes account activity, so the risk of deactivation through inactivity is far lower on a contract plan. If you are on PAYG and leaving the UK or simply not using your phone regularly, the six-month rule is the one to watch.
Deactivation is not always immediate. According to 2gosoftware.eu, a Vodafone prepaid SIM that has been temporarily blocked due to inactivity gives you a further 90-day window to top up and reactivate it. That is a total potential runway of roughly nine months from the point of last activity before the number is permanently lost, though Vodafone's own terms should be treated as the definitive source on this.
The simplest approach is to send a single text message once every few months. That resets the inactivity clock at essentially zero cost. If you are abroad for an extended period, a small top-up on a schedule (say, every four to five months) achieves the same result and keeps your credit from expiring. Some expats use a call-forwarding service so that any incoming call counts as activity on the UK SIM.
Once a number is fully deactivated, Vodafone can recycle and reassign it to another customer. At that point, recovering your original number is unlikely. If you believe your SIM was deactivated recently, contact Vodafone customer services on 191 (from a Vodafone phone) or 03333 040 191 (from any other phone) as soon as possible. The sooner you call, the better the chance that the number has not yet been reassigned.
Any unused credit on a deactivated PAYG SIM is forfeited. Vodafone does not refund credit on deactivated accounts in standard circumstances. This is another reason to act the moment you receive the 180-day warning text, particularly if you have a meaningful balance sitting on the SIM.
