China Mobile and my family sent a small amount, which was free in the first year, and 20 yuan per month in the second year was a pit.

China Mobile's small gifts and family members are free in the first year and 20 yuan every month in the second year, which may be a promotion strategy or a service charging method. Whether it is a pit or not requires more background and details.

If you have any questions about this charging method, I suggest you contact China Mobile Customer Service to learn more about the details and charging standards of this service, so that you can make an informed decision. At the same time, we can also compare the prices and functions of other similar services in order to make a more cost-effective choice.
