To be able to make and receive calls abroad, you need to activate the swype International rate.
If you want to activate the swype International rate when you’re already abroad, please first connect your device to a WLA Internet network, log into the swype app and then activate the swype International rate.
In addition, you will need to adjust the settings on your device as follows to allow an automatic selection of the network:
iOS devices/iPhones: Settings -> Cellular -> Network selection -> Select automatically
Android devices: Settings -> Connections -> Mobile networks -> Carrier -> Select automatically
