How to Call Multiple Countries with One App

Call Nigeria, Germany, Cuba, India, Pakistan, Uk — All from One App? Yes. Here’s How It Works.

Ever needed to call your mom in Nigeria, your cousin in Canada, and a client in Germany, all in the same day? That’s the world we live in now. Friends, family, work, we’re more spread out than ever.

But international calling? Still frustrating.

Some apps need the person on the other side to install the same thing you’re using. Others only work if you’ve got strong Wi-Fi. And too often, you’re left juggling different apps, expensive international plans, or worrying about your caller ID showing up as some unknown number.

So the big question is: Can you actually call different countries, landlines or mobiles, from one app, without switching between platforms or burning money on roaming?

You absolutely can. And not only is it possible, it’s finally practical.

Why People Need One App for Global Calling (And Why Most Apps Still Fail)

Making international calls shouldn’t feel like solving a puzzle. And yet, for many, it still does.

Let’s break it down:

• One app might let you call your cousin in the UK, but not your aunt’s landline in Zimbabwe.

• Another might work, but the other person needs to download it and figure out how to use it.

• Some work well on Wi-Fi but break the moment you’re on regular data or traveling through low-signal areas.

• And then there’s the mystery of pricing,  hidden setup fees, connection charges, random costs that weren’t mentioned upfront.

For people who live and move between countries, or who have loved ones scattered across the globe, this isn’t just inconvenient — it’s expensive and unsustainable.

If you’re calling three or four countries regularly, you shouldn’t have to manage three or four different apps or calling plans. You should be able to do it from one place — simple, clean, no drama.

That’s the gap Mytello fills.

What Does “One App for All Countries” Actually Mean?

It’s not about some magical all-in-one super app. It’s about practical coverage — having the ability to call a mobile or landline number in another country, without restrictions or hoops.

Here’s what that means in everyday terms:

• You don’t need to install multiple apps just to reach people in different countries

• You’re not stuck asking everyone to use the same calling app

• You don’t need strong internet every time you make a call

• You don’t need to buy local SIM cards or change your existing phone plan

• You’re able to make international calls to over 220+ countries using a single service

With Mytello, this happens via local dial-in numbers, meaning you dial a number that looks local, but it routes you internationally without the high cost.

It works with your current carrier, phone, and number, whether you’re using a smartphone or even a classic button phone. And if you prefer apps? You can use the free Mytello app for iOS or Android to make it even easier.

What Features Actually Matter When Calling Multiple Countries?

Forget the sales pitches. Let’s talk about what you actually need when calling multiple countries from one app or phone.

1. Works Without Internet

This one is huge, especially for users who travel a lot, or who have family in areas where internet is spotty.

Mytello works via local dial-in numbers. That means your call goes through the regular phone network, not the internet. So even if you’re in a café with weak Wi-Fi, or you’re calling a family member who only has a basic landline, the connection still works.

Apps that only support VoIP (like WhatsApp or Skype) may drop calls or not work at all in these scenarios. That’s a deal-breaker for people in areas with low internet penetration.

Mytello makes sure you can connect, every time. ➡️ Check Mytello country rates

2. Call Any Number — Not Just App Users

Some apps only work if both people use the same platform. That’s fine if you’re calling your tech-savvy friend in Tokyo. Not so helpful if you’re trying to reach your grandmother in a remote village.

Mytello lets you call any real phone number, landlines or mobiles, in any of the 220+ supported countries. The other person doesn’t need to download anything or sign up.

This makes it perfect for calling elderly relatives, local businesses, or anyone who doesn’t live in the app economy.

3. Transparent Pricing, Always

Let’s talk numbers, because nobody likes surprise fees.

With Mytello, you see the rate per minute upfront. No connection charges. No minimum monthly spending. Just pay for the time you use.

Here’s what that looks like:

• 🇳🇬 Nigeria – 13¢/min

• 🇵🇱 Poland – 1¢/min

• 🇨🇺 Cuba – 79.6¢/min

• 🇪🇹 Ethiopia – 23.8¢/min

You can view the full list by country (and even search by country name): ➡️ Explore rates here

4. Easy App, Simple Setup

If you’re using a smartphone, the Mytello app makes international calling even smoother.

It filters your contacts to show only international numbers. You just tap and call, no country code confusion or dialing strings.

You can also monitor your call credits and history directly in the app.

With fast support available 24/7, it’s designed to be stress-free, even if you’re just testing it for one call.

So, Which App Really Works Best?

If you’ve searched around, you’ve probably seen dozens of options for making international calls. Some are free, some offer credits, and some only work if both users are online. So let’s break things down in a way that’s actually useful.

Comparing Mytello to Other Apps in the Market

Here’s how Mytello stacks up against some of the most talked-about platforms in 2025:

Who Should Use What?

This is where intent really matters. Here’s how different user types typically match with the best app:

✈️ For Frequent Travelers

You’re hopping across countries, juggling SIMs and data plans.
Go with Mytello — no need to worry about internet access or local plans.

💬 For People Calling App-to-App (Like Friends)

WhatsApp or Telegram might work fine, but they both need internet and both people to use the app.

👨‍👩‍👧 For Families in Different Countries

If you’re calling parents in Kenya, a sister in the UK, and a cousin in Canada, all on different phones and plans, Mytello lets you do it without asking anyone to change a thing.

🏢 For Remote Teams or Business Owners

If you need to reach clients internationally and don’t want to install a VoIP PBX or corporate system, Mytello can cover most day-to-day communication across borders, without extra hardware or compliance headaches.

Common Questions About Calling Multiple Countries

Let’s tackle some of the things people ask before switching to a single international calling app:

❓ Can I call both landlines and mobile numbers?

Yes. That’s the core of what makes Mytello useful. It’s not limited to just VoIP or app-to-app calls — you can reach any real phone number.

❓ What if the person I’m calling doesn’t have the app?

That’s the beauty of it — they don’t need it. You’re calling their phone number directly. No setup, no learning curve, no confusion.

❓ Will my caller ID show properly?

Yes, your caller ID will show depending on the dial-in setup and destination country. You won’t show up as “unknown” or “spam” the way some VoIP tools do.

❓ Do I need a SIM for every country?

Nope. Just your regular SIM and Mytello’s dial-in number for your country of origin. You can be in the U.S. and call Peru, Nigeria, the UK — all from one number.

❓ How is this different from Google Voice?

Google Voice is great, if you live in the U.S., have good internet, and are calling U.S.-based numbers. But for broader international calling, especially where internet is unreliable or inconsistent, Mytello is far more flexible.
