He hatched a plan to cheat a mobile phone distributor using ghost subscribers.
Tan Wee Kiang applied for 19 mobile phone price plans which entitled him to 19 Apple iPhones worth about $15,000, He did this using copies of people's identity cards (ICs) without their knowledge.
The phones were then sold for a profit in September 2010.
He disappeared for two years until he was caught during a gambling raid on a unit in Geylang.
Yesterday, Tan, 35, was jailed 15 months on six charges of abetment of cheating. Thirteen other similar charges were taken into consideration.
Tan was also fined $2,000 for another charge of illegal gambling.
In August 2010, Tan met a sales executive at mobile phone distributor Gold Card, whose job was to telemarket mobile and broadband subscriptions to corporate customers.
The executive asked Tan to refer potential subscribers to him.
Tan called the sales executive, telling him that his friend wanted to sign up and asked for blank application forms from him, which the executive gave.
Tan and an accomplice called Ah Roy obtained photocopies of ICs belonging to nine other people and used them to apply for new phone lines.
It is not stated in court documents how they got the copies of these ICs.
The initial fee, which ranged between $60 to $480 depending on the mobile phone price plan, were paid for by Tan.
