Nope. Given the nature of how ILP works differently from traditional insurance plan, you shouldn’t be charged extra.

I can think of a few possibility
1) Your agent is stupid and he doesn’t know how to differentiate.
2) Your agent scared you terminate policy, wants you to lock you in for longer, so he lied.
3) You have special riders (with different payment term, I know 1 or 2 companies have this funny thing but not sure if GE does) attached to this plan. But no matter whether you have the riders or NOT, you should pay the same amount monthly/yearly to the basic plan.

I think 1) or 2) is more likely. 3) is unlikely. Could be 4) but I’m out of my depth. Could be many things in insurance I don’t know about.
