yes you can both these steps work if you plan it right but you will get a new phone number on both
step a is order new broadband on an additional line
step b cancel your old broadband so it gets turn off the day before the new one is fitted
if you plan it right you will be without broadband for a day
another way is but it will cost you a 1-month broadband fee extra
here is what you need to do
do not cancel your old non contract broadband just yet
step 1 order your new broadband on an additional phone line. Openreach will come and fit you with another phone line with Vodafone broadband and a new phone number.
step 2 after the new broadband is up and running you can then cancel the first broadband as the first broadband is not in contract,

you can also do step 1 and 2 if you have a cap line or you just simply want a new line for some other reason you can also keep moving the broadband around as long as you don't go over the cooling off time
vodafone 14 days
sky 30 days
now tv 30 days
sse 60 days
I also have a second broadband line and I have moved my second line 5 times this year to other providers to get the best connection and speed which has worked very well for testing broadband provider and connections
