Firstly, confirm for yourself that these old exam room type  mobile phone jammer are available for purchase, what are the models, and where are the manufacturers. If necessary, the original manufacturer should be contacted in a timely manner to inquire if there is room for upgrading the original model.

Based on experience, if the purchase date is four or five years ago for exam type  mobile phone jammer, there is often no upgrade space available. Most manufacturers only reserve the installation space required for the upgrade module in advance two or three years ago. Once there is no upgrade space, there is no need to worry too much. As long as the original exam room type  mobile phone jammer can still work properly, it can at least maintain its original working performance, and should still be able to completely interfere with the 2G, 3G, and 4G signals in the  mobile phone jammer.
