Yesterday I purchased a new SIM Card for use in my unlocked mobile phone during this visit to Cambodia as the previous one had expired.
It has long been the law that foreigners must have their passport photocopied to get a SIM Card but this was largely ignored and most phone shops happy to accept your national photo ID Driver's Licence with Home Address on it. Not any more! Neither my new series Cambodia photo ID Driver's Licence with Cambodian address on it nor my Australian Heavy Vehicle Driver Licence acceptable any more. It was passport or nothing! But as in most things in Cambodia there is a middle path. Just used a friend's National ID Card to make the purchase of the SIM and everyone very happy allround! One minute later had a Cellcard 089 prefix SIM card with full services and including $2. call credit for purchase price of $5. and back in contact with my Khmer friends.
All best regards to all. Ian
