Day 10 with MR I am happy, in terms of the deal, the speed (100/50), service desk response, and overall switch over experience.
Yes it took 4 working days before I can receive incoming call going during the switch over (I am able to make outgoing calls out on the very same day) - but if it is a big deal to you... then better to check again with MR or existing provider how long it would take....
The suggestion from not to deal with VF before everythings done was very helpful!! switch over and termination went smoothly.
