5 Hidden Costs of International Calling (And How to Avoid Them)

Whether you're catching up with family back home, calling a customer overseas or contacting a hotel while travelling, international calling costs can quickly add up.

The good news? Many unexpected charges are avoidable once you know what to look for.

Here are five common costs to watch out for, and how to keep your international calls affordable.

1. Connection fees: paying before you even speak

Some international calling providers charge a connection fee every time you make a call, on top of the regular per-minute rate.

That might not sound like much, but it adds up quickly if you make frequent calls.

Here's an example:

Imagine you call your family in Ghana 20 times a month. Your provider charges a €0.30 connection fee per call.

That's €6 in connection fees alone, before you've paid for a single minute of conversation.

How to avoid it

Check whether your provider charges a connection fee in addition to its advertised calling rate.

With Talk360, there are no separate connection fees. You can check the rate for your destination before making a call, so you know what to expect.

2. Minute rounding: paying for time you didn't use

Not every international calling provider bills you for the exact time you spend on the phone.

Some round every call up to the next full minute.

For example, if you speak for just 1 minute and 10 seconds, you could be charged for 2 full minutes.

That difference might seem small, but imagine making several short calls every day to customers, suppliers or family members.

Here's an example:

You make ten calls lasting 1 minute and 10 seconds each.

• Actual talk time: 11 minutes and 40 seconds
• Billed time if rounded up: 20 minutes
• Extra billed time: 8 minutes and 20 seconds

Over a month, that can make a noticeable difference.

How to avoid it

Look beyond the advertised price per minute. Check how your provider calculates call duration and whether it rounds up to full minutes.

A slightly higher per-minute rate with fairer billing can sometimes work out cheaper than a low advertised rate with aggressive rounding.

3. Roaming charges: calling abroad while you're abroad

International calling and roaming aren't the same thing, but it's easy to confuse them.

International calling means calling a number in another country. Roaming happens when you use your mobile network outside your home country.

And when you combine the two, costs can rise quickly.

Imagine you're travelling in Spain and need to call your bank in South Africa. If you make the call using your regular mobile network, you could face roaming charges, international calling charges or both, depending on your plan.

How to avoid it

Instead of making an international call through your mobile operator, use an internet-based calling app over Wi-Fi or mobile data.

With Talk360, you can call regular mobile phones and landlines in over 190 countries using an internet connection.

That means you don't need to use your mobile operator's international voice calling service.

Just remember: if you're using mobile data while roaming, your network's data charges may still apply.

4. Unexpected taxes and surcharges

Sometimes the price you see isn't quite the price you end up paying.

Depending on your provider, location and payment method, additional taxes or fees may apply to international calling services.

These could include VAT, local telecommunications taxes or payment-related charges.

Here's an example:

You find an international calling service advertising €0.10 per minute. But when you purchase credit, an additional tax or processing fee increases the total amount you pay.

The advertised calling rate might still be correct, but the overall cost is higher than expected.

How to avoid it

Before purchasing calling credit, check the total amount you're paying, including any applicable taxes or fees.

Choose a service that clearly displays calling rates and purchase costs, so you can make an informed decision.

With Talk360, you can check destination-specific calling rates before you call.

5. Mobile data costs: when internet calling isn't completely free

Apps like WhatsApp, FaceTime and Talk360 use an internet connection to make calls.

That's convenient, but an internet connection isn't always free.

If you're calling over Wi-Fi at home, you generally won't face additional mobile data charges. But when you're travelling or using a limited mobile data plan, calling over the internet can consume part of your data allowance.

And if you're roaming outside your home country, that data could be expensive.

Here's an example:

You're travelling abroad and make several long calls using mobile data. If your plan doesn't include roaming data, you could receive an unexpectedly high bill from your mobile provider.

How to avoid it

• Use Wi-Fi whenever possible.
• Check your mobile data allowance before travelling.
• Consider a travel eSIM or local data plan.
• Monitor your data usage when making longer calls.

Talk360 works over Wi-Fi or mobile data, giving you the flexibility to choose how you connect.

And unlike app-to-app calling services, the person you're calling doesn't need internet access. They simply answer their regular phone.

How to compare international calling costs

The cheapest advertised rate isn't always the cheapest way to call.

Before choosing an international calling provider, ask yourself these five questions:

• Connection fees: Small charges can add up across frequent calls
• Billing increments: Rounding can increase the cost of short calls
• Roaming charges: Your mobile operator may charge extra abroad
• Taxes and surcharges: The final purchase price may exceed the advertised rate
• Mobile data costs: Internet calls still use Wi-Fi or mobile data

It's also worth considering whether you need a monthly subscription or can simply pay for the calls you make.

For people who call internationally at different times or to different countries, a pay-as-you-go service can offer more flexibility.

Frequently asked questions

What's the cheapest way to make international calls?

It depends on who you're calling. App-to-app calls using WhatsApp or FaceTime can be free apart from internet costs, provided both people use the same service.

If you need to call a regular mobile phone or landline, an international calling app like Talk360 can be a cost-effective option. Compare the rate for your destination before calling.

Can I make international calls without roaming charges?

Yes. Using an internet-based calling app over Wi-Fi means you don't need to make the call through your mobile operator's roaming voice service.

However, mobile data roaming charges may still apply if you're not connected to Wi-Fi.

Can I call someone internationally if they don't have internet?

Yes. With Talk360, you can call regular mobile phones and landlines internationally. The person receiving your call doesn't need internet access or the Talk360 app.

Do international calling apps charge connection fees?

Some do, and others don't. Always check the provider's pricing structure before calling. Talk360 doesn't charge a separate connection fee.

Do I need a subscription to make international calls?

Not necessarily. Talk360 offers pay-as-you-go international calling, so you can add credit and use it whenever you need to call abroad, without a monthly subscription.
