Customer service is terrible, probably THE worst I have come across. Saying this, I would not even be able to judge since they don't even bother picking up. I called several times wanting to switch numbers from old sim card to a new micro sim. Waiting time is ridiculous; spent well over 15mins waiting before hanging up. Continuously tried for a couple days and even tried emailing them and I still got no response. Only after emailing their separate complaint email address I got a response well after two weeks by then I had already decided to use the new number instead. Don't even bother to try call their customer service.
