How to solve the problem of poor mobile phone signal
If the mobile phone signal is not good, it will directly affect our mobile experience. After all, the initial design of the mobile phone is used for calling. If the signal is intermittent during the call, it is estimated that you want to smash the mobile phone at the moment. Normal standby, if the signal is not good, will also affect our normal life and office. In view of the signal problem of the crew members, I have summarized some solutions to the signal problem.
Check the signal strength of SIM card
If you want to solve the problem of bad signal, you must first determine whether the signal of mobile phone is strong or weak! In general, if the signal is between - 40dbm and - 90dbm, the call will not be disconnected; if the signal is between - 90dbm and - 100dbm, the call may drop; after - 100dbm, the call will be dropped. [hide] enter the mobile phone interface set by the mobile phone, click the status and information of the interface, and then click the network to clearly see the signal strength.
Put aside the influence of external on mobile phone signal
1: Make sure the SIM card chip is complete
Because the current SIM cards need to be cut, it may cause damage to the SIM card in the process of cutting, and a little bit of cutting will affect the signal. Therefore, I also hope that you can go to the business hall and ask the staff to help reduce them.
2: Keep away from metal mobile phone protective case
I don't know if you have noticed one thing. There is a white belt behind P9 (it's not necessarily white. It's a tape anyway). This' white belt 'is mainly used to receive and send mobile phone signals. To get good signals, you must make sure that the two are exposed. Metal will affect the signal, so do not use metal The protective shell.
3: Change the place where the signal is good during the call
If you call in the elevator, do you think the quality of the call will be good? You're in the underground garage. Do you think the signal will be good? Let's not make trouble, OK? You're all in the signal blind zone, and the FBI can't find you! Quickly find a good signal place.
And then we'll deal with the signal from the inside
1: Very effective signal enhancement method (can effectively solve 80% of the human signal problem)
Signal reception is nothing more than 4G / 3G / 2G. Although 4G has become popular now, it does not mean that the 4G signal in every place is the strongest. Therefore, we should choose the appropriate signal source and switch the 3G, 2G or 4G signal of mobile phone according to different situations. We can see the signal above to decide which signal is better! Enter more settings of the mobile phone, and then select the network mode in the mobile network.
2: Mobile dedicated lifting signal method
The mobile version of p9 can't use the above method, because it seems that mobile operators don't allow 3G options (silent ~ ~), but it's hard for me. We enter the mobile network settings interface, then enter the access point name (APN) and select new APN.
Then modify the name of the access point, set the name to [cmtds], set the APN to [cmtds], pay attention to the case, select save, and then select the APN as cmtds.
The main reason is that most people choose cmnet and cmwap. Cmtds is rarely used by people. Moreover, cmtds is more stable and can keep the network speed in a stable state. This tutorial can effectively solve the problem of mobile phone surfing the Internet in prosperous places, but the network speed suddenly slows down. Because there are too many mobile communication ports around, switching back and forth ports leads to signal congestion.
