"Belgacom’s customers can now receive real-time usage notifications and access continually updated information about their charges for both national and international data services usage. This ensures that the company is providing customers with even more information than required under the latest EU regulations on data roaming. These new regulations will see further capping of international roaming charges from July 2012 [see "EU Helps Preventing Mobile Bill Shock" - here] and warnings for customers when they hit a €50 limit on their data roaming usage, with approval needed for further spending".
