Can someone send me a text message when the mobile phone signal is interfered by the mobile phone shielding device?
Many people are concerned about a question. Can someone send me a text message when the mobile phone signal is interfered by the mobile phone shielding device? Or can the previously sent text messages be received after unblocking?
Answer: After the mobile phone signal is interfered by the mobile phone shielding device, the text messages sent to you by others cannot be received by your mobile phone at that time. Of course, it is also impossible to make and receive calls. After unblocking, that is, the mobile phone shielding device is turned off or leaving the area covered by the mobile phone signal shielding device. If it is a text message sent to you by someone else on the same day, you will receive it. If it is earlier, such as yesterday or earlier, this It depends on whether the SMS service of your mobile communication service provider has this function.
Similarly, if you are blocked by your mobile phone, after someone dials your call, if your mobile phone has enabled caller or call reminder and other similar services, you will receive a short message reminder of missed calls after the signal is restored.
Everyone knows that the cell phone signal jammer can shield the mobile phone signal, but how does the jammer make the mobile phone no signal?
Mobile phone signal jammers can be large or small. There are many channels in any frequency band of mobile communication. In terms of technical terms, they are channels, and channels can be used as BCH. For example, which channel is used as a BCH in a cell : BCH can be determined entirely by the MSC according to the distribution of channels in the entire network area, but everyone who knows knows the instability of BCH, and there is uncertainty in shielding occasions, even in some cells. Two or more BCH, so when using a mobile phone signal jammer, it is to interfere with all channels of the mobile communication network that may appear in the use range, which is usually called CDMA, GSM, DCS , PHS, TD-SCDMA, WCDMA, etc., interfere with the frequencies in these channels, and use this to interfere with our mobile phone signals, and cut off the channels for mobile phones to receive signals as a whole.
