Trying out a new provider while still with VM
So my contract with VM is coming to an end. In my account, I was offered a deal for another 24 months which is very similar to what I've been paying and since I'm quite happy with VM service, to avoid the hassle of switching, I signed up for it.
But in the meantime I was looking at other providers and one in particular (Onestream) has a much cheaper offer which looks tempting (providing I use my own router to save on router costs - I have an old Plusnet Hub One router which I think should work with FTCC).
So I'm tempted to sign up with Onestream and test them out within the cooling off while still on VM and then decide which one to keep. I'm worried that if I switch completely, I will lose that deal that VM gave me.
This should theoretically be possible, right?
