I have left 5 Lao sim cards at "The Office" bar, off Sukh soi 33 as I live too far from BKK.

There are only 5 cards, so be quick,

they are supplied at cost: 100bt (25,000kip)

includes 15,000kip of call time.

Don't forget to copy all of your contacts to your "phone" before use.

Ask for K.Bob.

cheers

This is for information purposes only:

DTac sim cards from Thailand work quite well in Vietiane. I never had any trouble using mine around Vientiane. Just make sure you load up with some credit before you leave Thailand.
