If you have no reception or cannot make calls or send texts the SIM card is inactive. Was it a pay as you go or contract? Either way the contract would have expired if it is old and if your new SIM card has the same number than the SIM card would have no affect at all. Bluetooth is a free service and can be used on phones or USB stick etc. You will not have to pay for bluetooth. However if you want to reactivate the SIM you will have to contact your service provider.
