Don't forget VM are switching their MVNO from EE to Vodafone this year. Then there is the merger with O2 which should be approved this summer and the future prospect of them then switching to O2 mobile coverage.
I would check the signal coverage in your area for Vodafone, and if not good enough then wait until the O2 merger and mobile reassignment completes.
It might also be worth your while looking at the Oomph packages which include Sims. You may find a suitable pricing which includes your mobile usage. Depending on your requirements the Ultimate Oomph may be suitable.
Then call up and negotiate a new price with retentions.
You could also get a sim free phone elsewhere and use the VM sim in the phone
This Staff post from the community forums explains about porting your number from a VM mobile number to an Oomph package
