Received my new simcard via delivered, but why I cannot activate my simcard tho I've already follow the instructions that being state. Sending unifi ON (DMP NUMBER) to 63001. But keep received this kind of messaged "RM0 unifi: The DMP order number you've entered is invalid. Please try again." May I asked why? Since before this I'm using others plans but right now I'm switchin in to unifi via port-in. Can u gimme any help or clarify this matter with me? Thanks.
