The gap
For personal app calls, WhatsApp is often enough. The problem is not WhatsApp itself. The problem is assuming every international call can happen inside an app. Many calls still need to reach a real phone number such as a family landline, a clinic reception, a school office, or a business contact.
When the other person cannot or should not use WhatsApp, you need a different method. That could be a mobile carrier, Google Voice, an app-based calling service, or Talkala. The right choice depends on how the recipient can answer.
Choosing the method
If the other person can answer inside WhatsApp, use WhatsApp. If they need their regular phone to ring, use a service that connects to the phone network. The distinction is simple but it changes which options make sense for the call.
Talkala is designed for that second situation. You call from the browser, see the price before dialing, and the recipient answers on a normal mobile or landline without installing anything. That makes it practical for reaching people who do not use calling apps.

Best options
Browser calls to real phone numbers
Talkala lets you call real mobile and landline numbers abroad from your browser. You top up a prepaid wallet, check the per-minute rate before each call, and pay only for what you use.
Limitation: Not a free app-to-app voice or video calling service.
Phone-plan fallback
Your mobile carrier can call any international phone number directly from your phone plan. Useful when you need to dial quickly and do not want to set up another service.
Limitation: International rates are often expensive and hard to predict before the call.
