Pay as you go vs contracts in the US for mobile phones


#1

I’m wondering, for the long term, does it make sense to go with contracts for mobile phones in the US?

I found a site known as “calling Taiwan” which allows you to buy US sim cards in Taiwan, so you don’t get stuck without internet or whatever the moment you land.

Is AT&T better than T Mobile? I notice T Mobile is cheaper. They have a plan that offers 1gb full speed internet (that turns into Edge once you go over) and unlimited voice/text for 50 dollars a month.
