I have recently renew my contract on Singtel Shop Online by purchasing an N73. It offers free delivery and there is a discount of $30 if you order between 9PM to 9AM. The N73 phone was great but I forgot to inspect the 3G sim card which comes free with it. I was inform that once the 2G sim card is deactivated, I can use the 3G sim card straight away. My 2G sim card was deactivated the next following day. I only discover that the 3G sim card issued to me was wrong as it failed to register on Singtel Network. I called the customer service and found out that the sim card issued was incorrect. The sim card no given to me does not tally with the invoice sim card no. Please ensure you check your sim card no tally with the invoice sim card no if u use Singtel Shop.
