How about a wireless network card? Talk to friends who have used it, or have any better recommendations.

1. If ordinary broadband can be installed, wireless network card service is not recommended. In terms of cost performance and stability, there is a considerable gap between wireless network cards and ordinary broadband. Although the limit speed may be higher than broadband, there will be many restrictions on traffic or time, and after that, the cost will be quite high.

Among 2.3G wireless network cards, Unicom has the best speed, followed by telecom, and the mobile speed is the worst. In terms of 3G network coverage and stability, telecommunications is the best, followed by China Unicom, and mobile is the worst. It can be said that if you have been using it in the same big city center, it is recommended to use Unicom because the speed is the best. If you travel frequently or need to use it in rural areas between big cities and small cities, telecommunications is the first choice. As for moving, I will not consider it;

3. In terms of tariffs, it is definitely different because of geographical and economic differences, and different operators are also different. The same operator also has different tariff packages, so you should consult the operator's customer service directly.

4. In terms of wireless network card equipment, Huawei is the best one at present, followed by ZTE, and the price is generally around 200 yuan. I suggest you choose these two brands of wireless network card products, which have good stability and good use effect.
