I received a Huawei Y2 tablet last week (17/18 Feb). The next day a consultant called to activate the Sim. I was told it would take up to 72 hours. It is still not active (Wed 25th)I called the number ***. Take the activation option on the voice menu. just rings. Held on for 10 minutes yesterday. Called to day (25 Feb) at 3 pm, no reply, called, took logistics option, just rings, called the 3rd option, just rings.. tried chat on telkom mobile, they can't help..
