Does the GSM900 frequency band in the mobile phone signal blocker only block 2G signals?<\/h2>\n\n\n\n

Many mobile phone signal blockers will indicate the GSM900 frequency band logo in the product introduction, indicating that the signal of the GSM900 frequency band can be blocked. This makes consumers begin to doubt whether the GSM900 frequency band refers specifically to the 2G frequency band and whether the mobile phone signal blocker only blocks 2G signals.<\/p>\n\n\n\n

If this question was asked ten years ago, the answer would be yes, because the GSM900 frequency band at that time did refer to the frequency range of the 2G standard. In the mobile phone signal blocker, the GSM900 frequency band is responsible for blocking signals within the frequency range of the downlink signal, and the specific frequency range is as follows: national standard 930-960MHz, European standard 925-960MHz.<\/p>\n\n\n\n

However, with the advancement of technology and the rapid development of 4G and 5G networks, as well as the continuous 2G network decommissioning projects initiated by network operators, the GSM900 frequency band has changed. Operators have implemented a strategy to reuse the original GSM900 frequency band and redeploy and reallocate it. Therefore, today’s GSM900 frequency band not only covers part of the original 2G network, but also includes mixed 3G and 4G mobile phone signals.<\/p>\n\n\n\n

Despite these adjustments, the impact on Cell Phone Jammers<\/a> is not significant. Even with the addition of 3G and 4G signals to the GSM900 frequency band, the overall bandwidth of the band has not been significantly modified. The signal shielding provided by the mobile phone signal jammer for this band still fully covers the range of 930-960MHz. Popular WIFI jammers<\/a> and GPS jammers<\/a> in Europe and America are worth buying.<\/p>\n\n\n\n

Finally, the mobile phone signal jammer 930-960MHz frequency band, of which 930-933MHz belongs to Tietong, 935-949MHz belongs to Mobile, and 949-960MHz belongs to Unicom.<\/p>\n\n\n\n
