LONDON (Dow Jones)--BT Group PLC (BT) is to increase the cost of calls from land lines by 10% this autumn, the Daily Telegraph reports Monday. The minimum cost of making a call will now be 17.3 pence due to changes to connection charges and call rates, the telecom giant says, adding the rise in charges was needed to prop up its finances to survive the effects of the recession. A weekly daytime call will now cost 6.4p a minute, up from 5.9p and connection charges will rise from 9.9p to 10.9p, while monthly line rental will rise 50p to GBP12.04, the report says. BT has begun writing to its 12.5 million customers to warn them of the price rises, which begin in October, it adds.
