I dont see how the use of an hour or so of evening calls can provide significant load on their services.

I recently took out a t-mobile contract (everyone 3000 / 18 month @ £30 / month) I put the sim in a sim router so that i could make calls from my land line to mobile lines during the evening for very cheap. after the first bill arrived with no additional charges i was very happy. A couple of days later i received a letter stating that i was in breach of contract because my sim was being used in a sim box and that it would be terminated in 14 days with me subject to a charge of £30 x 16 remaining months. My own normal mobile line has now been suspended as i have not paid the cancellation fee on the other sim. Not happy A friend told me that t-mobile cancelled a contract with HBOS recently (trying the same charge) and lost a case on grounds that t-mobile cannot charge for a service they are not providing. Is there aything i can do to resolve the situation in either of the following manners: 1: they reconnect the sim and i continue saving money on my land line to mobile calls 2: they remove this crazy charge - and take back any equipment supplied 3: one of the above and some sort of compensation for any reason someone can think of
