Reply To: Received a ~RM600 legal demand form Maxis for defaulting on payments after leaving the country, do I need to pay?

No issues returning to Malaysia, and no criminal action either. They send this as a scare tactic to thousands of people hoping they pay up, it is rarely followed through due to the costs involved. Your amount owed is not worth it.

However, you will face difficulties getting a phone/internet line (and probably loan) if you do ever plan to return to Malaysia.
