your phone is black listed, you will also be able to get on-screen balance (*#1345#) and your number (*#100#), I have a T68i with the same symptoms and it is blacklisted. this also happens with nokia 8310's on voda too, dont know why I think its something to do with the data packet size, if its small enough the network wont ask for the phones IMEI and messages go through fine.
dont work on any other network though. strange.
