An important part of any mobile phone specification is its operating frequency band. The supported frequency band determines whether a particular mobile phone is compatible with a particular network operator. If you buy a cell phone jammer in Germany, you need to know the cell phone frequency bands used in Germany. 2G was first introduced in 1992. It is the second-generation mobile phone technology and the first technology to use digital call encryption. 2G networks were the first to provide data services and SMS text messages, but their data transmission rates were lower than their successors. Like almost all countries in Europe, Germany uses the GSM frequency band as the main telephone communication frequency. The two mobile radio communication networks are D-Netz and E-Netz, which are composed of D-Netz’s D1 and D2 standards, and E2 and E-Netz’s e-plus standards. D-Netz network uses GSM900 frequency band to work, E-Netz uses GSM1800 frequency band to work.
Most people just won’t mess this up. There are two good options to hide your information. The first is a cell phone blocker, which will hide you for a short period of time, but you will not be able to make or receive calls. The second is to avoid storing private and valuable data on your portable device, smartphone or tablet. Both will impair the functionality of your device, but they will certainly prevent data loss. The second thing to worry about is wireless networks. They are unreliable, and hackers take advantage of this fact. Most smartphone users connect to free Wi-Fi hotspots in public places, not only for surfing the Internet, but also for installing updates and processing their mobile banking information. This is quite dangerous, especially for Android users, because the Android operating system uses a weak version of SSL encryption and RC4 algorithm instead of SHA1. If necessary, you can use a mobile jammer to handle it.
