Why can't I get emails forwarded to me or sent in groups sometimes?

1, you have called to complain about spam messages. After the mobile company accepts your question, as long as it is not a peer-to-peer message, it will block you.

2, your cell phone signal is not strong, often no signal or weak signal (cell phone problem)

3. Some areas are severely blocked, such as Shanghai World Expo Park, Beijing and Shandong.
