The cheapest way to call abroad

The cheapest way to call abroad is a free app call, if the other person uses the same app. For everyone else, from landlines to banks to hotels, prepaid internet minutes are the cheapest way to ring a real phone number.

That is the short answer. The long answer saves you a lot more money.

Because the price of the same call can swing from free to several dollars a minute depending on how you place it. Most people only find out when the bill arrives.

This guide shows you every option and what each one costs. You will learn:

• The five ways to call abroad, ranked from most to least expensive
• Why international calls cost so much in the first place
• When a free app call works, and when it cannot
• How prepaid internet minutes reach any landline or mobile
• What your calls would cost, with a calculator
• How to dial correctly, first time, every time

Let's dive right in.

There are five common ways to call abroad, and the price gap between them is huge. Here they are, ranked:

Notice the pattern? The more your mobile carrier is involved, the more you pay.

Roaming and pay-per-minute calls go through your carrier at its own rates. Add-ons make that cheaper, but you pay every month whether you call or not. Internet minutes and app calls skip most of the carrier chain, which is where the savings come from.

The quick decision

• Calling someone on the same app? Use the app. It is free.
• Calling a landline, business, or anyone not on your app? Use prepaid minutes.
• Need people to call you back? Get a virtual number.
• Travelling? Keep roaming off and call over a travel eSIM's data.

An international call has to pass through more than one phone company, and each one gets paid.

Your carrier carries the call out of your country. A company in the other country delivers it to the person you are calling, and charges your carrier for that. Your carrier then adds its own margin on top.

Without an international plan, that margin can be big. Verizon, for example, lists pay-per-minute international rates starting from $0.49/min. AT&T sells an international calling add-on for $15 a month per line.

Why internet calls are so much cheaper

An internet call skips most of that chain.

Your voice travels over the internet, which costs next to nothing, right up to the country you are calling. Only the last short hop, onto the local phone network, costs real money. That is why a minute can cost a fraction of a cent instead of dollars.

App-to-app calls are free, as long as both people use the same app and have an internet connection.

Messaging and video apps can call each other over Wi-Fi or mobile data at no charge beyond the data itself. For friends and family who use the same app, nothing beats it.

But here is the catch most guides skip:

An app can only call another app. It cannot ring a landline, a bank, a hotel front desk, or a relative who does not use it.

In practice, most people need both: an app for friends, and a cheap way to ring real numbers for everything else.

Wi-Fi calling is not the same thing

This one catches a lot of people out.

“Wi-Fi calling” in your phone settings is a carrier feature. It sends your normal calls over Wi-Fi when signal is weak, but they are still billed as normal carrier calls. Dial an international number with Wi-Fi calling on, and you can still pay international rates.

An app call or internet minutes are different: they never touch your carrier's calling plan at all.

Prepaid internet minutes let you call any phone number abroad at internet prices. The person you call answers a normal phone. They do not need an app or internet at all.

Here is how the call actually travels:

How it works at SimVala

• Buy a bundle of minutes to the country you want to call.
• Dial from your dashboard, on your phone or laptop, over Wi-Fi or data.
• One rate covers landlines and mobiles in that country.
• Unused minutes never expire.
• Pay in crypto, with no card, no contract, and no monthly fee.

Bigger bundle, cheaper minute

Minutes come in three sizes, and each bigger size cuts the per-minute price further. Here is India, one of the most called countries:

On the biggest bundle, calls to popular countries cost well under a cent a minute. India, for example, is $0.0028/min.

Here is how that looks next to a carrier's starting pay-per-minute rate, on the same scale:

Put another way: 600 minutes to India costs $1.68 here. The same 600 minutes at a carrier's starting rate of $0.49/min would be $294.00, and many countries cost more than the starting rate.

The hidden costs to check on any calling service

A low headline rate is not the whole story. Before you buy from anyone, check these five things:

Roaming is the most expensive way to call, so the trick abroad is to keep your calls off your home carrier.

Here is the setup that costs the least:

1. 1Turn off data roaming on your home line.
2. 2Install a travel eSIM for mobile data where you are.
3. 3Call friends with apps over that data, for free.
4. 4Call landlines, hotels, and businesses with prepaid minutes, over the same data.

Calling local numbers while you are there

Need to ring a restaurant, a taxi firm, or your hotel in the country you are visiting? Buy a small bundle of minutes to that country and call from your dashboard over your eSIM data.

It works the same way as calling home: the call rides the internet and rings their normal phone, with no roaming involved.

A travel eSIM is data only, so it has no phone number of its own. That is fine: your calls run over its data, and your home number can stay on your phone for texts.

Calling minutes are outbound only. There is no number attached to you, so nobody can call you back on them.

If you need a doctor, a landlord, or a delivery driver to reach you, get a virtual number in that country instead. It gives you a local number people can call and text.

So which one? If you mostly call out now and then, minutes are cheaper. If you call a country a lot, or need to be reachable there, a number with unlimited calls can work out better.

How to dial an international number

Use a plus sign, the country code, then the number without its leading zero.

Most countries drop that leading zero. Italy is a well-known exception, where landline numbers keep it. When in doubt, each country guide lists the right format.

Keeping calls clear

• Use a steady connection. Good Wi-Fi or 4G is plenty.
• Voice uses very little data, typically well under a megabyte a minute.
• Pause big downloads or video while you are on a call.
• On a train or in a lift? Signal drops cut any call, internet or not.
