International calling has a reputation for being expensive, and that reputation is not entirely undeserved. But the landscape has changed a lot in recent years, and there are now real options that make staying connected much more affordable—and, in some cases, nearly free.
For anyone with family living abroad, the cost of keeping in touch can add up fast. Whether you are calling a parent, a sibling, or an old friend, the goal is simple: a clear, reliable connection without an unpleasant surprise on your phone bill.
This guide answers the most common questions people ask about international calling, from free apps to per-second billing, so you can make informed choices about how you stay in touch with the people who matter most.
Can you really make international calls for free?
Yes, you can make international calls for free, but with important limitations. Free calling works when both you and the person you are calling use the same app and have an active internet connection. The moment you want to call a regular phone number, a landline, or someone without the app, free calling is no longer an option.
Apps like WhatsApp, Messenger, and Viber allow app-to-app calls at no cost, using your Wi-Fi or mobile data instead of a traditional phone network. This works well for calling friends or family members who are tech-savvy and always reachable online. But in practice, many people—especially in rural parts of Africa—do not have reliable internet access or may not use smartphones at all. In those situations, you need a service that can connect you to a regular phone number, and that always involves some cost.
The good news is that the cost can be very low. With modern VoIP-based calling apps, international calls can cost just a few cents per minute, making the difference between “free” and “nearly free” much smaller than it used to be.
What apps let you call internationally for free?
Several apps let you make free international calls when both parties are connected to the internet. The most widely used options are WhatsApp, Skype, FaceTime, Google Meet, and Viber. Each of these supports voice and video calls over Wi-Fi or mobile data at no charge, as long as you are calling someone else on the same platform.
Here is a quick overview of the most popular free calling apps and what they require:
- WhatsApp — Free voice and video calls; requires both users to have the app and internet access
- Skype — Free app-to-app calls; also offers paid plans to call regular phone numbers
- Viber — Free calls between Viber users, with low-cost options to call mobiles and landlines
- Google Meet — Free video and voice calls, best suited for scheduled conversations
- FaceTime — Free for Apple device users; requires both parties to use Apple devices
The key limitation across all of these is the same: the person you are calling needs to be on the app, online, and reachable. For many diaspora communities calling back to Africa, that is not always guaranteed. When you need to reach someone on a regular mobile or landline, a low-cost international calling app becomes the more practical solution.
Why are international calls still so expensive?
International calls are expensive because of the infrastructure and agreements that traditional phone networks rely on. When you call from Europe to Nigeria or Eritrea using a standard phone plan, your call travels through multiple networks, and each network charges a fee. These fees, known as termination rates or interconnect fees, are passed on to the consumer.
Several factors drive the cost higher:
- Interconnect agreements — Carriers in different countries negotiate rates for routing calls across borders, and these rates vary significantly by destination
- Infrastructure costs — Maintaining international cables, satellites, and switching equipment is expensive, and those costs are built into call prices
- Regulatory fees — Some countries impose taxes or fees on incoming international calls, which are ultimately passed on to the caller
- Lack of competition — In some corridors, a small number of carriers control the routing, which limits price competition
- Hidden charges — Many traditional providers add connection fees or per-call charges on top of the per-minute rate, making calls more expensive than advertised
The result is that calling certain African countries from Europe can cost many times more than calling within Europe itself. This is a genuine financial burden for diaspora communities who call home frequently, and it is one of the main reasons VoIP-based alternatives have grown so rapidly in popularity.
What’s the difference between VoIP calls and regular phone calls?
VoIP (Voice over Internet Protocol) calls travel over the internet, while regular phone calls travel over traditional telephone networks. This fundamental difference in how the call is routed is what makes VoIP calls significantly cheaper for international communication.
With a regular phone call, your voice is converted into a signal that travels through a network of physical telephone infrastructure, crossing multiple carrier networks to reach its destination. Each handoff between networks adds cost. With a VoIP call, your voice is converted into data packets and sent over the internet, the same way an email or a video stream travels. The internet does not charge per-minute fees for routing data, which is why VoIP calls can be priced so much lower.
There are a few practical differences worth knowing:
- Call quality — VoIP quality depends on your internet connection. A strong Wi-Fi or 4G connection delivers excellent call quality; a weak connection can cause drops or delays
- Recipient requirements — Some VoIP services require the recipient to also have the app. Others, like FroggyTalk’s international calling service, can connect to any regular phone number, so the person you are calling does not need the app or internet
- Billing — Traditional calls often bill by the minute with connection fees. Good VoIP services bill per second, meaning you only pay for the time you actually use
For most diaspora callers, VoIP is the smarter choice, especially when calling destinations where regular phone rates are high.
How do you make cheap international calls without the internet?
Making cheap international calls without the internet is harder than it used to be, but there are still options. The most common approaches are international calling cards, SIM cards with international bundles, and carrier add-on plans. Each has trade-offs in terms of cost, convenience, and reliability.
Calling cards were once the go-to solution for diaspora communities. You purchase a card with a set amount of credit and use a PIN to access discounted international rates. The downside is that many calling cards include hidden fees, such as connection charges, maintenance fees, or rates that drop after a certain time of day. Reading the fine print carefully before buying is essential.
A second option is a local SIM card in your destination country, which some travellers use to avoid roaming charges entirely. This works well if you are physically in the country you want to call from, but it is not practical for everyday use from Europe.
The most reliable long-term approach is a calling app that uses minimal data, even on a slow mobile connection. Many VoIP apps are optimised to work on low-bandwidth connections, meaning even a basic mobile data plan can support good-quality calls. If Wi-Fi is available, even a slow connection is usually enough for voice calls. The practical reality is that for most people living in Europe, some form of internet access is nearly always available, making low-cost VoIP the most accessible and affordable route.
Which is the best free calling app for the African diaspora in Europe?
The best calling app for the African diaspora in Europe is one that combines low per-minute rates, no hidden fees, reliable call quality, and support for the languages and destinations that matter most to you. For many African communities across Europe, that combination is hard to find in mainstream apps, which is why purpose-built solutions have become increasingly important.
When choosing a calling app to stay in touch with family in Africa, the most important factors to consider are:
- Whether the recipient needs to have the app or internet access
- The per-minute rate to your specific destination
- Whether billing is per second or rounded up to the minute
- Whether the app is available in your language
- Whether there are connection fees or other hidden charges
Mainstream apps like WhatsApp work well for app-to-app calls but fall short when you need to reach someone on a regular phone. Dedicated international calling apps designed for diaspora communities tend to offer better rates to African destinations and more transparent pricing. The ability to call any phone number, not just app users, makes a significant practical difference for families spread across different countries and different levels of tech access.
Language support is also worth prioritising. An app that works in your preferred language—whether that is Tigrinya, Hausa, Amharic, Arabic, or French—makes the experience more comfortable and reduces the chance of billing misunderstandings. You deserve to feel heard, seen, and understood, and that starts with an app that speaks your language.
