Shopping Guide - Where to find Mobile Phones in Bangkok
If you need anything done on your mobile phone, want to buy one, or need any mobile phone accessories, we suggest you wander around MBK Center and check things out at the different outlets there. The fourth floor seems to have tens of shops where you can be helped. Possibly you will be better off if you can speak the language, but you can try to get around in English.
MBK center can easily be reached by skytrain, a little walk from Siam Square. Best is to take the connection to National Stadium, and take the walkway into MBK from there.
Another place where there are a lot of phone outlets, is at Fortune Tower (lower floors), located at Rama 9 subway station (closeby on the upper floors lots of computer hardware and software, as well as a Tesco-Lotus hypermarket)
