Traveled thru asia
a couple of times overland, last time I was in Cambodia
I was able to get data on the sim card that was pretty cheap
and tethered to laptop
. Would suggest you invest in a pocket WiFi
devise 4G unlocked and with antennae get all this before you go. I tried getting local sims in different countries, local sims was easy and very economical, data however wasn't but that could be language issue.
In general WiFi
is available in hotels but the reach is poor. Could be a option to get a range extender/rebroadcaster in your arsenal (On these forums
heard good things about Ubiquiti bullet), but I have no experience with this devise. A simple USB WiFi dongle in a 12V router is a possible solution.
Asking in stores often brings blank expressions. As time passes I notice less options not more, for example difficult to get a Mobile telephone that takes antennae jack not since samsung3.
