Calling & Connectivity
Calling family abroad and sending mobile top-ups home are everyday costs for dual-culture households across the UK, and the apps that serve them run genuine refer-a-friend programmes. Rebtel — a Stockholm operator running since 2006 — gives both sides $10 in credit once a new user makes a first purchase of at least $1, with calling to more than 200 destinations and top-ups to over 150 countries. It is a telecoms service rather than a financial firm, so the FCA framework doesn't apply, and credit is denominated in US dollars worldwide even though UK customers pay in pounds. We score the size of the credit, how trivially you qualify and how fast it lands.

Calling questions
Is the Rebtel referral live in 2026?
Yes. Both sides receive $10 of Rebtel Credit once the new user completes a first purchase of at least $1 using a payment method not linked to another Rebtel account. The credit usually lands within hours and is spendable on per-minute calls or top-ups.
Why is the credit in dollars if I'm in the UK?
Rebtel denominates credit in US dollars globally. You pay in pounds on your card statement and your bank applies the conversion; inside the app the balance shows in dollars. Per-minute call rates are still a fraction of a typical UK mobile network's international charges.
Is an international calling app FCA-regulated?
No — it is a telecoms service, not a financial product, so FCA authorisation doesn't apply. What matters is that the operator is a registered telecoms business and that UK sign-ups are explicitly supported, which is what we check before listing.
