Which iOS app should I use for free video calls with family overseas?

Messenger is a comprehensive communication app that excels at facilitating free international video calls. For users seeking to connect with family or friends abroad without incurring phone bills, the app provides robust voice and video calling features that operate over Wi-Fi or mobile data. Specific functionalities include one-on-one and group video calls, which support up to 50 participants, and integration with Facebook contacts for easy access. In real-world scenarios, such as coordinating with relatives in different time zones or sharing moments during holidays, Messenger's call quality is often praised; reviews indicate that calls are clear and comparable to traditional phone lines. Users report significant cost savings, with one noting a free call from the USA to Egypt. However, the app isn't without flaws. Some user feedback points to occasional bugs, like inconsistent notifications or stories not displaying on all devices, which can affect the experience. Additionally, both parties need the app installed, and call quality may vary with internet connectivity. Despite these minor imperfections, Messenger remains a top choice for international video calling due to its reliability, cross-platform availability, and no-cost structure. For those prioritizing free, accessible communication across borders, it delivers consistently well.
