Mobile devices can be topped up with overseas internet boosters.

Roaming bills for your mobile phone may soon be a thing of the past. T-Mobile customers can buy Internet and Broadband Travel Boosters that start from as little as £1. As a result, internet professionals can top up to support workers going overseas this summer. As more rely on mobile internet to deal with work queries on the go, boosters are also the firm's response to pressure from consumers and watchdogs to slash their call and internet roaming rates.

Three and Vodafone recently announced similar schemes but T-Mobile’s offering is the first of its kind to cover the entire world.

“We are really proud to be the first UK operator to ensure our customers can continue to be connected, anywhere in the world – and have the peace of mind they’ll never come back to an unexpected bill,” said Ben Fritsch, head of propositions at T-Mobile.

Each time a customer logs on to the net via their smartphone or mobile broadband device while abroad, they are redirected to a web page where they can buy a booster that will prevent them from racking up pounds on their bill.

Deals start from £1 (3MB in Europe) but can reach as much as £280 (50MB for the likes of Qatar, Cuba and Brazil). T-Mobile’s Internet and Broadband Travel Boosters go on sale this week, with the cost either being added to a customers pay monthly bill or deducted from PAYG customer’s credit.
