This kind of cell phone jammer is very powerful

MMS-capable mobile phone is unique in its built-in media editor, allowing users to easily write multimedia information. If the phone has a built-in or external camera, users can create PowerPoint format information or e-postcards and send them to friends or colleagues. Currently, the application service has matured and become mainstream text formats. MMS is the second SMS (text messaging service), EMS (Enhanced Message Service) after the "third-generation messaging services." The director plans to collect more advice about workshop management of cell phone jammer .
Can only send and receive SMS text messages, EMS text messages can add ringtones, simple graphics and simple animations, MMS can send and receive greatly expanded media types, text, pictures and ring tones can be a simple transfer, complex images such as photographs, Large pieces of music charts and send the video clip you can better play the role of MMS. MMS is the industry standard by the two organizations, WAP Forum (WAP Forum) and 3GPP (3G Partnership Project: 3G Partnership) formulated. Therefore, MMS is designed to run in the upper WAP protocol, it is not limited to transmission format, support both circuit-switched data format (circuit-switched data), also supports the General Packet Radio Service GPRS format (general packet radio service). The technical group of cell phone jammer will perform the inspection item by item.
The working principle for the use of high-speed transmission technologies EDGE (Enhanced Data rates for GSM Erolution is a new technology to improve the data rate is GSM to third generation mobile communication system IMT-2000 transition stage and it is also known as GSM 384, because This technology allows data rates from the current 9.6kbit / s to 384kbit / s, this rate can support voice, Internet browsing, e-mail, video conferencing and other high-speed data) and GPRS support, the WAP (Wireless Application Protocol) as the carrier to send video, pictures, sound and text. Mobile phone short message capacity refers to the phone itself can store the number of short messages. The task of production month of cell phone jammer is very tight.
This feature facilitates the SMS family, need to retain the messages can be easily retained in the phone. The current capacity of mobile phone short message focused on the 10 - 250 between, of course, there are high-end smart phone short message capacity will be more. Now this feature has become a major buy mobile phones to meet consumer demand. SMS message sending function can be distributed to multiple users simultaneously, without having to individually send function. This feature is actually the one with the same content repeatedly sent text messages to multiple recipients, groups and groups in the past without sending the phone to spend a lot of time and effort. If the recipient of many, for example, 50 people, sending speed will be slower, and the number of charges is paid by the recipient. The workshop should implement the self inspection of mobile phone jammer.
Fast and convenient to send messages, do not find the phone numbers one by one by one to send, save a lot of repeated processes. At the same time send mass text messages to avoid leakage of the case, the person may be required to send all of Paul. Quickly send information: You can also send the same message to a large number of targets, and ensure that all objectives can be the fastest to receive. A lot of communication cost savings: up to each send a message of not more than 0.10 yuan, and no communication charges and roaming charges, can greatly reduce the customer's telephone charges section of communication costs. Typical is the use of mobile phones while driving. Final inspection of cell phone jammer  is very important.
