Yes, you can use it if your device is capable of connecting to WiFi. If you want to use your device as a telephone, you may use it with a telephone app.

Can I return my WiFi device to an airport different from where I picked it up?

That is absolutely no problem. You can also choose different methods for pick-up and return.

Will transmission fees be applied?

No, they will not. We will not charge you based on usage as it’s already included in the rental fees.

No, you do not. You only have to sign a contract with NINJA WiFi to use our services. Any devices that can be connected to NINJA WiFi are able to connect to the internet at only the cost of the rental fees.
