HalaPhone
HalaPhone is a browser-based calling service for individuals, remote workers, travelers, and small businesses that need to reach contacts abroad. It lets users call mobile phones and landlines in more than 200 countries from a computer or phone browser, without installing software or paying a monthly calling subscription. Customers add prepaid credit in amounts starting at $10, see the per-minute rate before dialing, and pay for the minutes used; unused credit carries over. The service also supports renting a local phone number or verifying an existing number for caller ID, importing contacts from a CSV file, and searching call history by contact, status, and duration with completed-call costs. International rates vary by destination and whether the number is a mobile or landline.
