That’s because a charge of £3.50 per extra 1GB will then be added to bills – as an example of how much this could cost, a full HD movie is around 4GB in size so one night in front of a movie will cost £14.
Unless you spend hours streaming or playing games online, 25GB is quite a lot of data and it’s likely that most customers won’t get anywhere near that when abroad meaning they won’t be charged.
As O2 explained in a statement to TechRadar Pro: “Less than 1% of our Pay Monthly customers reach anywhere near 25GB during occasional travel to Europe. If a customer’s UK monthly data allowance is over 25GB, from August 2 they will have a Roaming Limit of 25GB in our Europe Zone.
“This means they can use up to 25GB of their allowance at no extra cost – we’ll text them if they get close to the limit, and again if they reach it. A customer can still use data if they reach our Roaming Limit, but will be charged £3.50/GB.”
