Well, you'll be on honeymoon, I guess you'll spend most of your time WITH your wife..

I don't think you need the Noi2Big option, if you separate each other you can just call her / she can just call you at the normal rates, which are rather cheap. I really don't think you will have to call each other for 200 minutes every week... In any case, just activate the Noi2Big option on 1 of the 2 simcards, if 200 minutes are quite a lot, 400 seem to me quite nonsense.
