I've had the 40% F+F discount for the duration of my contract, and for the past 8 months on rolling. If I threaten to cancel, get a PAC code and wait for an offer to roll in... will I lose the discount?

If I don't actually cancel or get a PAC code, but just sign up to a new deal, will the 40% discount be retained?

Any one know how this works?

I believe if you sign up through EE direct channels (store, website, tele sales) you will keep your discount but of course that depends on if the family member or friend is still working for EE.

As above I believe if the person is still at EE you'll keep it, however the F&F is 30% now so I'm not sure if you'd keep the 40 or go down to 30.

Has it confirmed. While I don't change plan, it'll be 40%. As soon as I do the discount will remain on my account but reduced to £30.

Currently I pay £17 for 10gb of data on sim only rolling. Although I can get 16gb for £19.99 on a 12 monther... I think I might stick on 10gb for now

16GB for £19.99 is a deal available to new customers and old so while it is seriously discounted, existing customers get the same deal. I asked and they wouldn't budge so I asked for PAC to leave, next day retentions call me and offer me 18GB for £15.99 a month with U/L mins and txt. I accepted.
