I visit Thailand once or twice a year for 2 or three weeks at at time. I have an AIS sim card which I got a few years ago but keep it active by topping it up occasionally so as not to have to get a new one each time.
Can anybody tell me what is the best plan for internet, data, call, messages etc. and how to buy it.
Until recently there seems to be have been lots of options but all I can see now is one or seven day plans.
Any advice would be appreciated.
Thank you
