Yes, EG Sim is the main one. Personally, I still stand by the fact that if you're traveling with many people, the egg is a better deal as you can all share the fee. If you stay a looong time and you're alone, yes, the SIM card might be cheaper (Just to get the card with 1 GB of data costs 30,000W). For me, if I was staying less than six days, I'd stick with egg.
