A real UK +44 eSIM from BuyUKeSIM is marketed as a lifetime line in the sense that you keep the same mobile number for ongoing use - not a one-day disposable. To protect the number from recycling by carriers, you typically need a top-up on a schedule (for example every six months - confirm current wording on the homepage and terms). This page explains why that matters for WhatsApp, PayPal, and 2FA codes.
Why top-up matters
If the line expires, you can lose SMS for verification and recovery. Setting a calendar reminder for top-up avoids surprises. Always follow the latest instructions shown after purchase and in product / policy pages.
