Uniconnect Sims have the worst reach possible --- Please if you’re traveling to Malaysia, think twice before you fall in their trap of a pre-paid sim card and being cheap. My husband and I had taken a Uniconnect sim for Malaysia and it was a terrible. The number was dysfunctional all the time. There were signals but we could barely connect to any number, but everytime we would call they would charge money for the call even when it never got connected. And when we called the customer care and complained of this, they said its happening because the call is getting but there could be some problem with our handset as we couldn’t hear the oother person. That was it. Heights of tricking people and really really terrible service.
