Unicom's mobile phone card is quite good. Unicom's tariff is cheap, the network is stable, and the network speed is also very fast, such as Shen Bing card and ice cream package. At present, it has cooperated with third-party companies such as Tencent and Alipay to launch a series of Internet-specific packages such as Tencent Wangka and Alibaba Baoka. Call, traffic and other services are more affordable. I suggest that you can also choose the right package according to your actual use.
