I can’t see where to give data?

in overview, right there "Gift" unless you have no data in your plan or you are out of data to give or you are the last day or second last day of your cycle.

If you want to gift unused data at the end of your payment cycle, you can gift it right up to 48 hours before your current payment cycle ends. Once this cycle is over, however, the data will roll over — it will no longer be available to send as a gift.

OK, found it ,but I try to give to some of my contacts,I have this message:
“This plan currently doesn’t have enough data to give away”
I do have 4,37 go left in my plan!?!

Are you more than 48hrs before the end for you cycle (month) ?

Gswim, yes I am ! Is that the problem?
