At present, some regions have introduced the corresponding policies for network transfer. Mobile to Unicom and mobile telecommunications are all possible, and the three companies can definitely transfer to each other. However, in general, the choice for the transfer package is the remaining packages. For example, if you originally paid 18 yuan, he will change it to 21 yuan, or 25 yuan. You think there is no difference between a few dollars.
when choosing a set meal, you should first determine what your needs are usually used for. Most people may. The demand for making a phone call is not so strong, because it is easy to make a voice call through social software now, and the traffic is directly taken. There is basically WiFi in your home or work unit, so you basically don't need this package with a particularly long call time, unless you need to contact customers for business needs and make a phone call, then you have to do this voice package. In most cases, it is recommended to do that kind of package in the province with a large traffic.
make sure you can accept this price in the package. When your actual demand is determined, you should leave some space. For example, if you think you can use 1.5 G of traffic a month, then I recommend you to choose 21 G, because in this case, you can support the consumption of this traffic. If you go to do a value-added package of traffic, the price will be very expensive, which is basically the case for major operators, and it is still time-limited. At this consumption level, you should choose one that you feel acceptable.
Although the three major operators say that they can gradually shift their consumption to each other, the essence has not changed. Because the three major operators have jointly carved up more than 91% of our domestic communication market, this change is still limited. You can't expect him to suddenly reduce your traffic and communication costs, and he will make money.
