Short answer: Lyca Mobile UK says a Pay As You Go number may be reassigned if there has been no activity for 90 days. Its current public page does not promise a further 30-day notice or recovery period.

What the current Lyca page confirms
Lyca's accessibility policy says UK rules require some chargeable activity to keep a Pay As You Go account active. It then says a number may be reassigned after 90 days with no activity.
The previous KeepSim article described “90 days plus a 30-day notice”. The old FAQ now redirects to Lyca's home page, and the current policy does not repeat that notice window. That claim has therefore been removed.
What should you do before day 90?
Complete a chargeable action that Lyca accepts for your exact PAYG plan, then check My Lyca or contact support to confirm the account remains active. The current public policy does not publish a complete list of qualifying actions, so this guide does not guess whether a particular incoming call, Wi-Fi message or bundle event resets the clock.
If the number is important, top up or buy the appropriate plan well before the deadline and keep the confirmation. Do not wait for a warning text: the public policy does not guarantee one.
Can a reassigned number be recovered?
Lyca only says its team will try to help if you contact it quickly. It does not promise that an inactive or reassigned number can be restored. Once another customer receives the number, a reminder app cannot reverse that allocation.
Read what prepaid inactivity actually affects, compare the UK rows in the carrier table, or return to the UK carrier section.
Set the reminder before day 90
KeepSim can remember the date you last completed a confirmed Lyca action. It cannot perform that action or verify Lyca's account state.

- 2026-08-01: removed the unconfirmed 30-day notice period and narrowed the answer to Lyca's current wording.
KeepSim is not affiliated with Lyca Mobile. This page uses “medium” confidence because the current public page does not define every qualifying activity or a recovery window.
