Trang (Thailand ) starting mid January, how is internet there?

Thinking about Trang, but need at least a 5M download internet
Will be hard to get it?

any suggestion about Trang is welcome (need to find a cheap apartment, and need also to stuck in front of my laptop to work :wink:

does is also make sense, for a 3 month stay, to get a 3G sim and use it to work? (my traffic is 20G per month)
