For years, Skype was how many people called phones abroad. Microsoft retired it on May 5, 2025, and stopped selling Skype Credit, calling subscriptions and Skype Numbers.
Microsoft also says the free version of Teams does not support paid calling plans. So anyone who used Skype to call a landline or a mobile now needs another way to do it.
If you are looking for a free Skype alternative, it helps to know what free covers. Free apps like WhatsApp call people who use the same app, over the internet. A bank, an airline, a hotel or a landline needs a call on the phone network.
That is what CallTuv is for. Unlike most apps like Skype, it rings ordinary phone numbers, and the person you call doesn’t need anything installed.
