How much is Shengsen's communication flow card?

I didn't know what the imaginary number was until I used it. I bought a card 200g before, but it was actually 100g g.

Good cards, whether agents or customers choose cards, are nothing more than the following two points. One is stability and the other is after-sales service. One is stability, that is to say, the application of wooden boards must be long-term and reliable. Under normal circumstances, the Internet of Things card cannot be used on mobile phones, but the rights and interests force all kinds of enterprises to wave after wave. Although operators have banned them in batches, the sales market has been in a wildfire and has never completely consumed them. They have grown taller in the spring breeze, and then amaranth has been cut down wave after wave. So the stability of the card is particularly important. Otherwise, in this scenario, your customers will bombard you with WeChat at different time intervals. Why does my card suddenly stop working? Why does the network card die? Why does it take the king so long to eat chicken? Why did the Internet speed wait so long? You feel fine for a day or two, and suddenly you collapse.
