14 International Chat Apps for Personal and Work Communication in 2024

Communication apps are a must-have in today’s interconnected world. They’re a lifeline as more and more people go abroad for work, education, and leisure. With a stable internet connection, you can send text messages and other data, while voice over internet protocol (VoIP) technology allows you to make phone calls, no matter where in the world the other party is, and often for free.

Chat apps aren’t just for free international text messages and calls, though. As remote work takes hold across the globe, these apps can help employers and employees meet the challenges of telecommuting, such as real-time collaboration across long distances and time zones.

The Best International Chat Apps for 2024

So which apps are the best for chatting internationally? Whether you’re collaborating at work or just checking in with friends and family back home, we’ll break it down for you below.

1. Skype: The best app for international chat and low-cost calling

Skype

Skype needs no introduction. The pioneering platform has provided reliable communication capabilities since 2003.

It’s a great option for chatting with coworkers or friends back home.

When it comes to business use specifically, Skype for Business was discontinued in 2021 and replaced by Microsoft Teams.
