We’ve all read those horror stories where people have come back from a holiday abroad to be greeted with a bill of hundreds or even thousands of pounds because they forgot to turn off the date roaming function on their mobile device.
3G/4G enabled tablet computers automatically seek out mobile connections and use them to update apps, even when you are not using them.
So, to be safe, you need to turn off the data roaming in your tablet settings before you go away, otherwise these devices could be downloading data at standard rates throughout your stay, and you could be running up a high bill without realising it.
Remember, even low data usage that you wouldn’t notice at home could end up costing you more abroad as it may not be covered by your standard usage allowance.
