Is it free for obee to call? I was tricked into buying one. Yes, I checked 10086. Why?

Yes, it's free. Although making phone calls is free, it is not a money-saving mobile phone. There is a lot of charging software built in it. If you accidentally touch them, you will be charged. Even if you don't touch it, you have to charge (this is also a common problem of many domestic shanzhai machines). However, their manufacturers have also set up a disclaimer: Our company has the right to change the procedures without notice. Therefore, it is recommended that the landlord not use this mobile phone.
