Calling between Brazil and Portugal costs less than most people think — as little as $0.02–$0.05 per minute with the right VoIP app in 2026. With roughly 1.5 million Brazilians living in Portugal and tens of thousands of Portuguese nationals working across Brazil, this corridor is one of the busiest Portuguese-language calling routes in the world. This article breaks down the best apps to call Brazil from Portugal — and Portugal from Brazil — comparing real costs, app quality, and what actually works without roaming surprises.
Key Takeaways:
- GlobCall connects calls to Brazil from as low as $0.02/min, no app download, no roaming needed
- Apps like WhatsApp work free — but only when the other person is online and has internet; they fail for landlines and unavailable contacts
- Browser-based VoIP is the most flexible option: it works on any device, calls any number, and doesn't require the recipient to have any app installed

Why This Route Is Trickier Than It Looks
Portugal and Brazil share a language, but their calling infrastructure is worlds apart. Brazil is a massive country — calling a São Paulo mobile is different from calling a landline in Recife — and rates vary accordingly. Meanwhile, calling a Portuguese landline from Brazil can trigger carrier surcharges that aren't always obvious upfront.
Here's what most people miss: the shared language tricks people into assuming the call will be cheap. It won't be, unless you use the right tool. Standard mobile carrier rates for international calls from Portugal to Brazil hover around €0.25–€0.45 per minute in 2026. Brazilian carriers aren't much kinder in the opposite direction.
The real savings come from VoIP and browser-based calling — but not all of them are equal.
The 5 Best Apps for Calling Between Brazil and Portugal
1. GlobCall (Browser-Based VoIP)
GlobCall is one of the strongest options for this specific route. No app download. No SIM needed. You open a browser, top up a balance, and call any Brazilian or Portuguese number — mobile or landline — in about two clicks. Rates to Brazil start at $0.02/min. That's not a teaser rate; it's the standard pay-as-you-go price listed on the rates page.
If you're calling from Portugal, the full breakdown is on the call Brazil page. If you're in Brazil calling Portugal, the call Portugal page has everything you need. No roaming. No monthly fee. No seat charges.
For teams — say, a company with staff split between Lisbon and São Paulo — GlobCall's business plan gives you local numbers in 100+ countries, shared balance, and unlimited team members. No per-seat fees, which matters when you're scaling. More on that at the business page.
2. WhatsApp
Free, widely used, and very popular in both Brazil and Portugal. WhatsApp voice calls work well — as long as both parties are online, have the app, and have a stable internet connection. It's the default choice for personal calls between families and friends.
The problem? It only calls other WhatsApp users. You can't call a landline. You can't reach a business number. You can't call someone who doesn't have the app or has a different number than the one saved in your contacts. For personal use with family, it's fine. For anything beyond that, it falls short.

3. Viber
Viber has decent penetration in Portugal but lower adoption in Brazil compared to WhatsApp. Free Viber-to-Viber calls work the same way — both parties need the app. Viber Out (their paid tier) lets you call regular phone numbers, but rates vary and the interface isn't as clean as browser-based VoIP. Worth considering if both parties already use Viber, but it's not a reliable default for this corridor.
4. Google Voice
Google Voice offers cheap outbound calling, but there's a catch: it's built primarily for US users. You need a US number to set it up, which rules it out for most people in Portugal or Brazil. If you already have a US Google Voice number and you're traveling, it can help — but it's not designed for the Portugal-Brazil route. See the Google Voice alternatives page for more context.
5. Rebtel
Rebtel has historically served this route, particularly for users who make long calls regularly. It uses local access numbers to route international calls cheaply. The downside is that setup takes effort, sometimes a local SIM, and the rate structure isn't always transparent. It can work, but it's more friction than a browser-based option. Compare it directly at the Rebtel alternatives page.
What About Free Apps — Can You Actually Call for Free?
Sort of. "Free" international calls almost always come with strings attached. WhatsApp, Viber, FaceTime, and similar apps are free when you're calling app-to-app, both parties have internet, and you're not dialing a real phone number. That covers plenty of personal scenarios — but not all of them.
The moment you need to call a landline, a company, or someone who isn't on your app? Free stops working. You need a service that can terminate calls on the public telephone network, and that always carries a per-minute cost.

How to Call Brazil from Portugal in 3 Steps (Using GlobCall)
This is as simple as it gets.
Step 1: Go to GlobCall.com in your browser. No download required. Works on Chrome, Firefox, Safari — any modern browser on any device.
Step 2: Add credit to your account. Top up with a card or PayPal. Rates to Brazil start at $0.02/min. A $5 top-up gets you over 4 hours of talk time at that rate.
Step 3: Enter the Brazilian number and call. Dial with the country code (+55) and the full number. That's it.
No roaming charges hit your phone bill. No surprise fees at the end of the month. You pay only for what you use. If you're calling frequently, bookmark the call Brazil page for quick access.
Does It Work the Other Way? Calling Portugal from Brazil
Yes, and it's just as straightforward. Head to GlobCall.com, enter the Portuguese number with the +351 country code, and call. Rates are similarly low. The call Portugal page has the exact per-minute figure.
This matters especially for Brazilians who work with Portuguese clients, family members abroad, or government offices back home. Calling a Portuguese landline from a Brazilian carrier can cost 10x more than using browser VoIP. That's not an exaggeration — it's a documented gap that VoIP was built to close.

Frequently Asked Questions
Can I call a Brazilian landline from Portugal without roaming charges?
Yes. Browser-based VoIP like GlobCall lets you call any Brazilian landline or mobile number from any internet connection — no SIM required, no roaming. Rates start at $0.02/min, making a 30-minute call cost under a dollar.
What's the cheapest app to call Brazil from Portugal in 2026?
For calls to real phone numbers (not just app-to-app), GlobCall consistently offers among the lowest per-minute rates. WhatsApp is free for app-to-app calls but won't reach landlines or non-app users. For the full picture, see the cheapest way to call internationally FAQ.
Do I need to download anything to use GlobCall?
No. GlobCall runs entirely in your browser. No app, no plugin, no extension. As long as you have a microphone and an internet connection, you can make calls from any device.
Does WhatsApp work well for Brazil-Portugal calls?
For personal calls between family and friends who both use WhatsApp and have reliable internet, yes — it works well and it's free. But it fails entirely for landlines, businesses, or contacts who don't have the app. It's a useful first option, not a complete solution.
Is there a free trial for GlobCall?
Yes. GlobCall offers a free 60-minute call to try the service — accessible at /60-min-free-call before you commit any credit. It's a real trial, not a sign-up funnel.
