    Hi Vicky! No, you do not need to have separate cell phone jammers to deal with various mobile phone connection providers. You see, AT&T, Verizon, T-Mobile, Sprint and other mobile phones use different frequencies for their operation but they are also working in the same frequency band because they can’t break the standards of mobile communications. And now think about all you have just read. If they use the same frequency band in their work, do you need various cell phone jammers to block their signals? Of course not :) If cell phone jammer can successfully block GSM and 3G signals then it will block all types of mobile phones using those signals, and all mobile standards working using them too (like DCS, PHS, CDMA, and so on).
