Have had a rolling sim only contract for 4yrs, which is discounted because I have home broadband with BT. Will this be discontinued or will the price increase if I switch broadband provider?
If you no longer have BT broadband, you'll lose the £5 broadband discount, so the price will increase by £5 per month.
If you've had it 4 years, why not contact the Loyalty team and negotiate new discounts on your package ? a lot has changed in 4 years, worth a go before leaving, ring 08002 800 150
I am sure that its been said that provided you stay with BT Mobile, you will still get the discount, unless that has recently changed.
If you leave the broadband, the £5 discount is removed after 30 days, the only exception was previously the discount remained if the broadband was ceased due to a price change.
