WhatsApp review

WhatsApp ranks first because for most international calls the cheapest option is a call that never touches the phone network. Its calling page states that voice and video calls are free, have no time limits and are end-to-end encrypted, and the only cost is the data you use. Group calls hold up to 32 people with unlimited duration, which covers a family call across three continents, and you can share your screen or schedule a group call in advance. Calls work from iOS, Android, Mac, iPad and Windows apps, and WhatsApp Web lets you call straight from a browser. The limit is reach: WhatsApp cannot dial a landline or a mobile number that is not on WhatsApp, so a grandparent with a basic phone or a hotel front desk needs a different app. Travelers should also note WhatsApp's own warning that data charges may apply, so use Wi-Fi or a data eSIM rather than carrier roaming.
