To help keep users keep tabs on their spending, Three says it will allow caps to be added to accounts with a text message sent if a customer is getting close to their limit.
There says this should help avoid bill shock when returning from a summer break.
The company has admitted that it’s not been an easy decision to make but it’s had to introduce the changes to keep pace in the current climate.
Explaining more about the update, a Three spokesperson said: “Any customers who take out a new contract or upgrade with Three from 1 October 2021 will pay a charge of £2 per day when roaming within the EU applicable from May 23, 2022. PAYG customers and customers who have taken out a contract before 1 October 2021 are unaffected by these changes.
“Customers roaming in the Republic of Ireland are also unaffected.
“The new charge ensures that customers are clear on what they will pay when using their phone in another country and only those who roam will pay for the service. It will also ensure that we can continue investing in our UK network.”
