ANRITSU. 1993. Early in 1993? Telecom Australia set up one or two telephones for a surfing classic carnival in Vietnam. The cards used for this occasion had the same design as the Christmas Island $10 trial, Rwanda $50 D2, and Cambodian $2 OTC issues. These cards were printed and encoded in Australia as with all cards issued from around JUNE 1992. The prefix is 289, and the Vietnam cards lie between 0028910001 and 0028910200. YES ONLY 200 CARDS MADE, and records of sales indicate only cards #1 up to #73 were sold.

I have possessed only 3 cards at any time. Mine is 0028910028, card number #28. The reverse of the card is overprinted "VIETNAM" and "$50". The card was encoded in $US and could only be used on THAT phone at the surfing tournament, for the 2 weeks!!
