Will the IOU work while roaming?
The IOU service will work in EU Zone 1 destinations.
When you opt-in to an IOU while roaming you will be charged at the same rate as sending a text message home (from the country you are travelling in). The standard charge for using an IOU will also apply after topping up.
Check out our roaming rates to see how much it will cost to send an IOU from where you’re travelling. You can use our Top Up Direct service while roaming in EU Zone 1 Destinations too!
