Ultra Mobile International CallsPin

Ultra Mobile has one seriously cool advantage over most other carriers and MVNOs: free international calling to over 90 countries – here’s everything you need to know…



With Ultra Mobile International Calls, you get free unlimited calling to over 90 international destinations and text services to 190+ international destinations. And if that wasn’t enough to whet your whistle, keep this in mind:

While Ultra Mobile is an MVNO, it is powered by T-Mobile’s network which, in case you missed it, was recently rated as the fastest 5G network in the USA.

Add in the fact that Ultra Mobile’s plans come with zero strings attached and seriously attractive monthly prices, and it is easy to see why this carrier is starting to become very popular with users.

Ultra Mobile International Calls: What’s The Deal?

Plenty of MVNOs do cheap data, that’s kind of their whole deal. But none of them do free international calling. 

And this is where Ultra Mobile really comes into its own. In fact, for specific types of users it could very quickly become the only option in town. 

For instance, got family that live abroad? With Ultra Mobile, you’ll be able to call them for free. That is huge. 

I have family and friends all over, so this feature really appeals to me. But before we get TOO carried away, let’s first unpack the details and see if Ultra Mobile’s free international calling actually stacks up…

  • Network and Reliability: Ultra Mobile’s services are fortified by T-Mobile’s network, guaranteeing fast and reliable service globally. This ensures clear and uninterrupted international calls, allowing users to communicate without any hindrances.
