Which Carriers and Networks Do eSIMs Use?

The networks your eSIM connects to depend on the provider and plan you choose. Some eSIMs offer access to multiple networks in each country, which can improve coverage while traveling, while others may connect to only one.

When you purchase a Travel eSIM, you’ll get access to one or more mobile networks in each country you travel to. The exact networks you can connect to depend on the eSIM provider and the plan you choose.

Network Availability Varies by Provider

Each eSIM provider partners with different carriers around the world. Some offer access to multiple networks within a country, while others may only connect to one. Generally, the more networks your eSIM can use, the better your coverage will be - especially if you’re travelling across a country.

Choosing the Best Option for Travel

If you’re planning to move around within a country or across several countries, look for an eSIM that offers access to multiple networks. This ensures you’ll stay connected even if one carrier has weak coverage in certain areas.

Network Selection Tips

We recommend keeping your phone’s network selection set to automatic. This allows your device to connect to the carrier with the strongest available signal, so you don’t have to manually switch between networks as you travel.

In Some Cases, Only One Network May Be Available

It’s worth noting that in some destinations, an eSIM may only provide access to a single carrier. This isn’t unusual and still works well in countries with strong, reliable national networks.

So the next time you travel, check to see which networks you can connect to, to avoid black spots! If the eSIM provider has shared details about which networks they use, you’ll find this information by clicking “More Info” on the plan.
