Suparelay

Some calls only work on a phone number: your bank abroad, an airline, an embassy, a landlord. Suparelay makes that call from a browser tab. Type the number, see the price for that exact number, press call — and their ordinary phone rings, with no app, no account and no internet needed on their side. Prepaid credit from $5, from about 2 cents a minute, charged per started minute, and nothing at all if they do not answer. No subscription. The credit never expires.

Suparelay places real phone calls to landlines and mobiles in more than 200 countries and territories in a current browser. You install nothing, need no SIM and no phone number of your own. Billing starts when somebody answers (including voicemail); busy, rejected or unanswered calls cost nothing. Optional automatic top-up keeps a long call alive. US toll-free numbers connect from abroad.
