A second UK number is useful when you do not want app verifications on your personal mobile. Install the BuyUKeSIM eSIM as an additional line, leave your primary SIM for data, and register services on the +44.
You can buy up to 20 eSIMs in one order if you need multiple UK lines for team members or separate brands.
Second UK number vs replacing your main SIM
You keep your everyday number for calls and data. The BuyUKeSIM eSIM adds a separate +44 profile - ideal for WhatsApp Business, freelance clients, or privacy separation.
On dual-SIM iPhone and Android, set the UK line as default for SMS while your local SIM handles mobile data.
Multiple UK lines for teams
Checkout supports quantity up to 20 - each purchase is a fresh +44 with its own QR. Useful for agencies, marketplaces, or family members who each need verification lines.
Each line requires its own $15 top-up every six months to stay active - numbers do not share a pool.
