From the 1 of December 2006 all Thai Mobile numbers will change from 9-digits to 10-digits numbers. From midnight today the old 9-digit numbers will not work.
If you still have 9-digits numbers in your phone book, you will be unable to call these stored numbers. All you have to do is to edit your own phone book to include the extra “8” digit for Thai mobile phones.
If you send SMS add an “8” in your phone setting for “SMS Service Centre”.
If your old number was 01-6666666 your new number is now 081-6666666.
Ais, Dtac, Hutch and True all have service to help you change your number in your mobile in a few minutes if you not want to change by hand. Please locate your nearest Thai Mobile Center.
Local phones are not affected of this at all.
