Rebtel

Rebtel offers an app for cheap international calls to landlines and mobiles worldwide, using over 3G/4G, Wi-Fi or local phone lines. The service automatically selects the best phone line for each call and offers unlimited calling subscriptions, minute buckets and pay-per-minute rates.

Customers are individuals calling family and friends abroad, with per-country offers and limited first-time promotions. Revenue comes from calling subscriptions, minute bundles and per-minute rates; the website states there are no contracts or hidden fees.

The website lists Stockholm as the location of its open roles, with eight postings including .NET, Android, iOS, machine learning, data engineering and product management. The site is published in English, German, Italian, French and Spanish. The input does not state a founding year or headquarters address.
