Most of the staff at Mobile Phone, Internet and Cable providers speak very little English and understand less than they are willing to admit. You may think they understood you but don't bet your money on it. Once you have a contract even if it is wrong you are stuck with it. Some, but not all landlords will connect the internet for you then you just pay the landlord each month. If your landlord will not do this be prepared to pay for the first 12 months at about 700 baht per month in advance.
Our staff will ensure you get exactly what you want; nothing more and nothing less.
