If you want to surf the Internet wirelessly, you must have a wireless network card, which is the kind of external USB interface. There are two forms of monthly subscription, one is traffic and the other is duration, but the cheapest is 100 per month. From/kloc-0 to the end of the month, it costs more than 400 yuan to buy a better wireless network card (ZTE or Huawei network card is better). In addition, the wireless network launched by telecom can be accessed anytime and anywhere, and the other is the receiver that needs telecom (also needs wireless network card). In your case, it is not worthwhile to set up a wireless network just to place an order. In addition, there is no need to place an order every day. Therefore, it is recommended to use mobile phones to surf the Internet, which can achieve the same effect and the cost is relatively low.
