There are currently two mobile phone masts in the Similan Islands, one from DTAC and one from AIS. From most locations around the Similans you will get a phone signal and will be able to connect to a 3G network.
Should the transmitters be switched off like they were in late October when we were there you will be completely cut off unless you walk to Haad Lek (small beach) on Koh Miang (island number 4) and ask the Royal Thai Navy if you can use their wifi.
