How to Make Free or Cheap International Phone Calls (2026 Guide)

Got family, friends, or clients abroad? You don’t need to dread the phone bill anymore.

There are plenty of ways to call another country without paying your carrier’s standard international rates. Some are completely free. Others cost a few pence a minute. 

This guide walks through both — the free apps for calling, and the cheap options for reaching a real phone number abroad.

Free vs. Cheap — What’s the Actual Difference?

Free international calls only work app-to-app. That means both you and the person you’re calling need the same app installed, like WhatsApp or FaceTime. As long as you’re both online, the call costs nothing beyond your normal data or Wi-Fi.

Cheap international calls are different. These let you call a real phone number — a landline or mobile — anywhere in the world. The other person doesn’t need any app. You just pay a small fee per minute, usually through a carrier add-on, a VoIP service, or a calling card.

Free International Calling Methods (App-to-App)

These apps let you call anyone else who has the same app installed, anywhere in the world, for free. All you need is Wi-Fi or mobile data.

i. WhatsApp

WhatsApp is the easiest starting point. Almost everyone abroad already has it, so you probably won’t need to convince family or friends to download anything new.

You can make voice calls, video calls, and even group calls with up to 32 people. All calls are end-to-end encrypted, so no one else can listen in.

ii. FaceTime

If you and the person you’re calling both use Apple devices, FaceTime is built in and ready to go. No extra download, no setup.

It works on iPhone, iPad, and Mac. Call quality is generally excellent, and it’s just as easy to start a video call as a voice call. The only real limit is that both sides need an Apple device.

iii. Telegram / Signal

Telegram and Signal both offer free voice and video calls between users, the same as WhatsApp. 

Signal is worth knowing about if privacy matters to you. It’s a non-profit, doesn’t run ads, and encrypts every call by default. 

Telegram, by contrast, only fully encrypts calls if you turn on Secret Chat — its regular calls aren’t end-to-end encrypted the same way.

Telegram also handles larger groups better. Its voice chats can hold thousands of listeners, while Signal caps group calls at 75 participants.

iv. Google Voice

Google Voice is often recommended for free international calls, but it comes with a big catch for UK users: it’s built around a US phone number, and only US-based accounts can sign up.

Even for US users, “free” only applies to calls to the US and Canada. Calling anywhere else, including the UK, still costs per-minute credit that you have to buy in advance.

Cheap Ways to Call Real Phone Numbers Abroad

If the person you’re calling doesn’t have a smartphone, or doesn’t use the same app as you, you’ll need one of these options instead. They all let you call a real landline or mobile number abroad, for a small per-minute cost.

1. Browser-Based VoIP Services

These services let you make international calls straight from your web browser. No app to download, no account to set up on the other end.

You just top up with credit, enter the number you want to call, and dial. Rates typically start from around 2 cents a minute, depending on the destination.

Some services show you the exact cost before you connect, so there are no surprises on your bill.

This is a good option if you only need to call abroad occasionally and don’t want to commit to a monthly plan.

TwinPhone and BoraPhone is best to explore for this.

2. Rebtel

Rebtel is built for calling real phone numbers abroad, especially if your own internet connection isn’t reliable.

Calls between two Rebtel users are free. Calling a regular number costs a small per-minute rate, with especially strong pricing to India and much of Europe.

There are also unlimited monthly plans for specific countries if you call the same place often.

3. International Calling Cards

Calling cards are one of the oldest ways to call abroad cheaply, and they still work well for calling landlines, banks, or anyone without a smartphone.

You buy a set amount of credit upfront, dial an access number, enter a PIN, then dial the number you want to reach. Your call is routed through the card provider’s network instead of your normal carrier, which is usually much cheaper.

The one thing to watch for is hidden fees. Some cards charge a connection fee just for dialling, even if no one answers. Others round calls up to the nearest 3 or 5 minutes, so a 21-minute call gets billed as 25. Always check this before you buy.

4. Carrier international add-ons/bundles

If you’d rather keep everything on your normal phone bill, most UK networks offer an add-on specifically for calling abroad. You pay a fixed monthly fee and get either a set number of minutes or unlimited calls to a list of countries.

FAQs – Free International Calls

Q1. Is there a truly free way to call an international landline?

Not really. Free calling only works app-to-app, between two people using the same service like WhatsApp or FaceTime. A landline can’t run an app, so calling one always costs something.

Q2. Do free calling apps work without Wi-Fi?

Yes, but they’ll use your mobile data instead. Voice calls use relatively little data, but video calls can use up a lot more. 

Q3. What’s the cheapest way to call a real phone number abroad?

Browser-based VoIP services tend to offer the lowest per-minute rates, often starting from around 2 cents a minute.

Q4. Can I use Google Voice to call internationally from the UK?

No, not in any useful way. Google Voice requires a US phone number to sign up, so UK users can’t create an account through the normal route. Even for US-based users, only calls to the US and Canada are free — everything else, including the UK, is charged per minute.

Q5. Is WhatsApp really free for international calls?

The call itself doesn’t have a separate charge, but it still uses data. On Wi-Fi, it’s genuinely free. On mobile data, especially while roaming abroad, your carrier can still bill you for the data used, so check your allowance first.

Final Words – Free International Calls

There’s no single best way to call abroad. It depends on who you’re calling and what they have access to.

If the person you want to reach has a smartphone and a good internet connection, stick with a free app like WhatsApp, FaceTime, Telegram, or Signal. You won’t pay a penny beyond your normal data.

If you need to call a landline, an older phone, or someone without the same app, look at a carrier add-on, a browser-based VoIP service, or a calling card instead. Compare the per-minute rate against how often you actually call that country — occasional calls suit pay-as-you-go options, while frequent calls to the same place are usually cheaper with a monthly add-on.

Either way, you don’t need to let an expensive phone bill get in the way of staying in touch.
