Disadvantages: ①Cannot receive text messages, send text messages, or make phone calls.

② It can only be used for Internet access, not directed, not speed limited, but limited.

③The device will be locked, which means that if your phone has the card slot for card 1, you cannot change the card slot.

④Due to violations, there is a risk that the card will die halfway through use, but generally refunds will be given and the card will be replaced.

⑤The network speed generally depends on the local area. It will be a little slower than the normal traffic card, which is the level of ordinary video viewing at 720p

⑥Prohibited areas: Xinjiang, Tibet, Fujian, Guangxi, Yunnan , Maoming City, Qingyuan City, and Chaozhou City are not supported for the time being.

⑦ There is a 40% virtual amount, which means that the package marked with 22 yuan and 35G actually only gets 21G.
