Recently, I always receive information that malicious software invades my mobile phone, such as rainbow weather, animation, music on demand or magazine on demand.

My situation is exactly the same as yours. Are all products of mobile companies. I think it's a loophole in the mobile company. This question can be searched. It was published only recently. I called the labor service for a refund and was later detained. The mobile company said that the service was cancelled and it is still being deducted. I think the mobile company is very responsible. If we use their communication, they will also ensure the safety of the fees we use.
