Yes! – As we do not restrict data sharing, there is no reason why you would not be able to share the connection with other devices via WiFi (providing your device supports a “mobile hotspot” feature).
The data speed is restricted to 128 kbps (2G equivalent) when roaming so although this is sufficient for general use of apps on your phone it is not suitable for high usage such as video streaming. Additionally, if you share the data connection you should consider the impact this would have on bandwidth as it would generally be too low for most devices to run effectively.
Please note, although we do not expect for you to have issues, we are unable to provide technical support for data sharing. From our limited tests, we have found that data sharing works with most Android, iPhone and Mi-Fi devices, however, we cannot guarantee that it will work with every device.
