Sending a text message home to boast about a beach vacation should cost less than half of what it does now, EU regulators said Tuesday. The European Commission wants to set a price cap for text messages of 11 euro cents, far below the current EU average of 29 euro cents. The EU’s top telecom official, Viviane Reding, said she was putting the new rules forward because telecommunications companies had not responded to her call for them to lower text prices.
