As of September 01 2006, all mobile phone numbers will be changed to ten digit numbers. Those that begin with 01, 06 or 09, will instead begin with 081, 086, or 089 respectively. Old numbers will continue to be connected through to December 1, to allow people time to adjust to the changes. For those that have local mobile phones, please note that you will need to visit your operator’s office to have your SIM card updated. All numbers beginning with 02 (Bangkok land lines) will remain the same as will all upcountry land lines.
