FAQ
What exactly is an eSIM and how does it work for our travels?
An eSIM is simply a virtual chip already soldered inside your smartphone. We loved saying goodbye to fragile little pieces of plastic and the famous paperclip that you always end up losing!

Can we share the connection with other devices?
Yes, tethering (or hotspot) is allowed on Holafly plans. It’s super handy for helping out a computer or tablet! Note, however, that on unlimited plans, this sharing is often limited to 1 GB of data per day depending on your destination. We found this more than enough to check our emails or do a bit of work on the road.
