What are the benefits of China Mobile's 4g card?

First of all, you can be sure that the internet speed is faster and the tariff is cheaper for two reasons. First, because of the technical advantages of 4G, operators send out unit traffic, which is much lower than the cost of 3G2G, so there is more room for price reduction. On the other hand, from the perspective of promoting 4G, mobile hopes to get more 4G users, so they will seduce you with more cheap 4G traffic. I'm from Suzhou, and we have a discount here, that is, if you open the traffic of 10, you will be given another 550M 4G single-mode traffic every month, another 770M 4G single-mode traffic when you open 20 yuan, and two 4G single-modes when you open 40 yuan (4G single-mode traffic can only be used, so roaming will be charged). This is naked temptation to drive 4G. But I use the company's telecom card. I don't have to pay anyway. I had nothing to do with that. )

Then there is stability and quality of use. Mobile 4G adopts TD-LTE technology independently developed by China, so the Ministry of Industry and Information Technology issued a TD-LTE license six months ago. Telecom and China Unicom adopted the internationally popular 4G technology (LTE FDD), so although they also got the 4G license at that time, the license was TD-LTE, which had no practical use. However, the official license of (LTE FDD) adopted by China Telecom Unicom has not been issued so far (the trial license was issued on June 27th, and the 4G mobile phone service can only be carried out in the pilot city of 16), so the telecom only has 4G data service, but no mobile phone service. In fact, the main point I want to express above is that the Ministry of Industry and Information Technology originally approved TD-LTE for the sake of protecting China's independent 4G technology, and its own 4G development was earlier, so China Mobile was ahead of China Telecom and China Unicom in the development of 4G technology. At present, there are more than 320,000 4G base stations, covering more than 300 cities. In contrast, China Telecom Unicom is relatively backward due to the adoption of international 4G technology, so the Ministry of Industry and Information Technology issued the license late. Therefore, in the current situation, mobile 4G first has stable signal and wide coverage. And in the next year or two, even if the latter catches up, its signal is better than Unicom. PS: Another disadvantage of unstable signal is power consumption. Because the signal is unstable, the mobile phone will frequently connect the signal and convert it into 3G2G, so even if you put it in your pocket, it still consumes a lot of power.

Secondly, there is a joke that if you forget to turn off the data, your house will move overnight. In fact, no matter whether it is China Mobile Telecom Unicom, it will adopt the method of double capping of traffic charges, so don't worry.

Finally, it's free for you to change the 4G SIM card.

Since you are asking about the benefits of mobile 4G, I won't talk about the disadvantages, but I want to mention that Unicom's current 4G is not as good as mobile, because their development speed lags behind mobile, not to say that the LTE FDD technology they adopt is worse than mobile TD-LTE. The advantage of FDD is wide coverage, and the advantage of TD is long bandwidth.
