Living abroad or having family on the other side of the world shouldn't cost a fortune. This guide explains how to cut your international call and data spending to a minimum, with practical tips and real tools.
Why Are International Calls So Expensive?
Roaming tariffs and international calls from traditional carriers come with very high margins. A single minute of an international call can cost between €0.50 and €2 or more, depending on the destination and your plan. The good news is that real alternatives exist to bring that cost close to zero.
The Best Alternatives for Cheap International Calls
1. Free VoIP Apps (WhatsApp, Telegram, FaceTime)
If both you and the person you're calling have data or Wi-Fi, messaging apps are the cheapest option: free or virtually free. WhatsApp, Telegram, FaceTime and Google Meet offer high-quality voice and video calls at no extra charge.
Tip: Use Wi-Fi whenever possible so you don't consume your data allowance.
2. Data eSIM for Your Destination
If you're travelling abroad and need data without paying your carrier's roaming fees, a local data eSIM is the most cost-effective solution. For a few euros you get data at your destination and can call via WhatsApp or any VoIP app just as if you were at home.
- Without swapping your physical SIM: your number stays active to receive calls and SMS.
- Digital activation: buy online, receive a QR code and install it in minutes.
- Plans from just a few euros for days or weeks at your destination.
3. International Top-Ups for Prepaid Phones
If your family member abroad has a prepaid phone, sending them a top-up is a simple and affordable way for them to call you back. In destinations like Cuba, Venezuela, Nicaragua and other Latin American countries, a top-up of just a few euros makes a big difference for staying in touch.
4. Paid International Calling Apps
Specialist apps (Rebtel, Skype, Google Voice) offer international call rates far lower than traditional carriers — useful when you need to reach a landline or someone without internet access.
Tips to Cut Your Spending to a Minimum
- Schedule your calls: use Wi-Fi whenever possible and plan longer conversations for when you're at home or on a reliable network.
- Buy a data eSIM before you travel so you have cheap data from the moment you arrive.
- Send a top-up instead of calling: if your family member has a prepaid phone, a top-up lets them call you.
- Avoid your carrier's roaming: activate it only for emergencies and rely on eSIM data or Wi-Fi for calls.
- Compare VoIP apps: WhatsApp is the most universal, but Telegram and FaceTime offer better quality on slow connections.
Frequently Asked Questions
Can I call abroad for free from Spain?
Yes, if you use apps like WhatsApp, Telegram or FaceTime and have data or Wi-Fi available. The call has no additional cost beyond your standard data allowance.
Which is cheaper, an eSIM or my carrier's roaming?
In most cases a data eSIM is considerably cheaper than standard roaming from Spanish carriers outside the EU. Within the EU roaming is usually included in your plan, but outside it can multiply costs tenfold.
How can I help my family member in Cuba or Venezuela call me?
The simplest way is to send them a top-up to their prepaid phone via TuRecargas. With credit on their phone they can call you or connect to the internet and reach you on WhatsApp.
