Although the iPhone’s 5g chip seems to be taking back the advanced features of the iPhone, it’s time to bring back the power of the 5g. < / P > < p > in the preview a few days ago, foreign media have already introduced the three gear “5g data mode” of the iPhone 12 series intelligent machine. However, before you start with the iPhone 12, you’d better consult your local carrier about 5g band and base station coverage. < p > < p > at present, the millimeter wave (mmwave) with higher speed but poor signal coverage and penetration ability is the most frequently moved out in current publicity. By mixing some bands with 4G LTE, operators can provide quite good 5g mobile network experience. However, in the less densely populated areas, the frequency band below 6GHz with wider coverage, stronger signal penetration capacity and relatively low speed is more suitable. Of course, remember not to be cheated by the “fake 5g” propaganda of some operators. < / P > < p > compared with at & T “5Ge”, which was complained by T-Mobile before, it is still based on 4G LTE network. In addition, some operators may require users to change their SIM cards or upgrade their packages to give full play to the full strength of 5g mobile networks. < / P > < p > to get to the point, let’s take a look at the IOS setting process shared by 9to5mac. IPhone 12 smartphone users who need it can find the default “5g mode configuration” menu under “Settings – & gt; cellular – & gt; data options – & gt; voice and data”. < / P > < p > according to the actual demand, users can choose to scan 5g network all the time, auto switch, and 4G LTE network only. If 5g auto is specified, you can also select third gear data mode in the cellular data option. Global Tech
