fyi, you’ll pay fees with everyone, its just a matter of whether or not they diguise them in the price or not. telefonica/movistar won’t show you the fees you pay, buut they are thhere none the less. same with amena. they can’t get around paying the 16% vat either, so thats what your seeing I believe.
I personally prefer vodafone anyway, you can get cheap calls to other vodafone subscribers and they have english customer service. hard to beat that for expats. oh yeah, plus vodafone is everywhere in europe, so it’s much easier to recharge in other countries and get better rates.
just my 2 cents
