Interested to know what it's like as I'm considering EE. How have you found the process so far?
Couldn't have been simpler, transfer was seemless though I did have one moment of hesitation in that I couldn't connect using the old white openreach modem as I always have with BT and Sky, however I just bypassed it and worked fine thats hardly EE's fault though.
Been very happy with the service so far and the info available is good with even a guide for using your own router supplied though I'm using the EE one for now until the 'bedding in' period is up. Had to ring customers services once during the process regarding billing which was dealt with straight away, I had a £10.55 early termination fee from BT which I've uploaded to EE and had confirmation that this has been credited already.
Speed is better, ping times are the same so basically all good so far.
The 5gb data boost is going to be added at any point during the next 30 working days and the £137.50 quidco cashback can take upto 90 days to track so can't really feedback back on those yet.
