Safe internet and mobile content
Nowadays, children begin to use the Internet from a very early age. The net offers all kinds of information, and at the same time it hides risks for anyone. Regardless of the fact whether Internet access is gained through the personal computer or mobile phone, at any given time children can be faced with inappropriate content if certain rules are not followed. It is important to have open dialogue between parents and children about the virtual reality so that what is interesting can also be safe.
As a responsible company and mobile data provider, Yettel feels its own duty to make sure the customers have the safest internet experience possible. Because of that at the end of 2014 we became the first telecom in Bulgaria, which launched a filter that blocks web domains containing child sexual abuse materials. The initiative was launched in cooperation with the Bulgarian Ministry of Interior. The filter will be effective for all users of the operator’s mobile data services. Thus, Yettel subscribers attempting to access a website with child abuse content via the company’s mobile network will be automatically redirected to a “Stop Page” notifying them that the website they are trying to access is banned. The filter blocks a list of domains which is prepared by the International Criminal Police Organization INTERPOL and the Bulgarian Ministry of Interior based on a predefined set of criteria. This blacklist contains websites with images or movies depicting sexual exploitation, harassment or misuse of children.
As a corporately responsible company Yettel offers some practical advice for safe Internet surfing.

Partnerships
Unified donation system DMS
The company has a long lasting partnership with the Bulgarian Donor’s Forum and Bulgarian Charities Aid Foundation, by supporting the project DMS in Bulgaria (a unified system for SMS donation) as a donation instrument. DMS imposes a uniform number for all charity campaigns and for all participating mobile operators, thus introducing unified criteria for access by people who need treatment or other medical procedures, organizations and institutions. DMS guarantees feedback to donors about funds collected and the amount spent and imposes unified price for donation SMS, which is equal for all campaigns and participating operators. DMS gives legitimate NGOs, public institutions and individuals in Bulgaria the opportunity to raise funds for charity via one of the easiest ways for donations - short text messages.

„Team of Hope“
Yettel is an official sponsor of the so-called „Team of Hope“. This was part of the Homeless World Cup Bulgaria project, a football tournament for underprivileged boys and girls with the aim of social integration of these people through sport. The tournament is part of the preparation and selection of the national team that represented Bulgaria at the World Cup for homeless people. Almost all players in the „Team of Hope“ have grown up in homes for children deprived of parental care but had to leave them due to their age and they are now homeless. Some of them are currently living in temporary accommodation centers, but often remain in the streets without shelter or food. The project, Homeless World Cup Bulgaria, aims at achieving social integration of homeless youngsters through football, and the results have been excellent.
Electromagnetic fields
The policy of Yettel towards our clients is one of absolute transparency and constant engagement to keep them informed about the company’s activities and the field we are working in. This principle motivated us to pay attention to a question that is interesting for our customers as well as for the whole society.
The topic of electromagnetic fields (EMF) of mobile phones and base stations finds its place on the agenda of the society, and Yettel is responsible to provide its clients with comprehensive and accessible information about the question.
That is why the company adopted a Policy on electromagnetic fields and created an information brochure in which we offer an objective view over the most important questions about EMF. The content of the material is made with the support of the Telecommunications Faculty of The Technical University – Sofia.

Frequently Asked Questions
How does the mobile phone work?
GSM means Global System for Mobile communications, and it is a digital cellular radio net, functioning in more than 200 countries around the world. When you dial a number or send a message, your phone emits radio waves. These waves are received by the nearest network cell (base station), which relays them to the base station in the range of which the number you are trying to reach is located. Radio waves or radio frequencies were discovered about 100 years ago and are part of the electromagnetic spectrum, which covers radio waves emitted by radio and television stations as well. These radio waves fall into the group of the so-called “non-ionizing emissions”. Unlike the “ionizing emissions”, which include X-rays and Gamma rays, the energy released by the non-ionizing emissions cannot destroy human molecules. The only thing which is observed is an insignificant increase in the temperature of the human tissue.
This is due to the fact that these radio waves cannot penetrate deep into the human body and their energy is transformed in molecules’ motion. It is the friction, caused by the moving molecules, which leads to the emission of thermal energy and increase in the temperature. However, it is quite small in this case. The strength of the radio waves, emitted by mobile phones and base stations, is monitored by independent agencies and state institutions. For the purpose of monitoring, a parameter called Specific Absorption Rate (SAR) is introduced. SAR is a measure of the amount of energy absorbed by the body while using a mobile phone. International standards and guidelines on the limits of SAR have been adopted and taken into consideration in the production of mobile phones. Every manufacturer of such devices is obliged to indicate the SAR levels in the documentation for the device. There is information about the compliance with the international standards for SAR in the box of any phone purchased from Yettel.
What is a base station?
A base station is a transceiver working through radio waves. It connects your mobile phone with the mobile operator’s cellular network. Each base station provides coverage in a specific geographical area. Base stations are connected in order to allow subscribers to receive reliable connection when moving from one cell to another.
What determines the number and the location of the base stations?
One base station supports a small number of simultaneous calls at a certain moment. As the usage of mobile phones increases, it is necessary that the number of the base stations should also increase, so that mobile operators can provide the necessary quality of the services offered.
In addition, the base stations working under the standards for mobile telephoning and data transfer - GSM (Global System for Mobile Communications), UMTS (Universal Mobile Telecommunication System) and LTE (Long Term Evolution) - are designed to work with a much lower output power – from 2 to 22 watts. That is why every base station has a limited area of operation, and it should be installed next to the places where the mobile phones are used, including residential and business complexes.
Are electromagnetic fields harmful to human health?
The biological effect from the EMF has been studied in the last 50 years, as 200 million euro was spent on research in the last decade. 100 million euro of it was invested especially in researching the impact of mobile phones on human health.
By 1995, more than 20 research and government agencies had analyzed the scientific evidence relating to the effects of EMF on health. The overall conclusion is that there is no evidence of unhealthy effects of EMF at levels below the internationally accepted limits.
The strength of the radio waves is bigger at their source and declines rapidly with the distance from it. According to the World Health Organization (WHO), emissions from base stations and wireless technologies are thousands of times weaker than international standards. In fact, the body absorbs up to five times more radio and television waves than those coming from the base stations. This is due to the frequencies used – in FM radio they are about 100 MHz, TV broadcasting is between 300 and 400 MHz, and mobile telephony ranges between 900 and 2100 MHz.
What are the international and Bulgarian standards for safe exposure to EMF, produced from mobile phones and base stations?
The limits for safe exposure to EMF are specified by competent international organizations such as: the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and WHO. ICNIRP defines the maximum EMF exposure limits. That limits are sufficient for people protection and thus many countries in the world uses them as a basis for establishing internal standards, which local mobile operators should comply with when building their networks. In Bulgaria, the EMF limits are determined by Ordinance №9 of the Ministry of Health and are stricter than ICNIRP.
What are the standards in Bulgaria for the installation of base stations?
In Bulgaria, the installation and putting into operationputting into operation of every base station is subject to a two-step control. It includes the issuance of a special permit from the Ministry of Health prior to the commencement of the building of the base station, and real measurements of the actual values of the EMF of the base station prior to its putting in operation. Moreover, subsequent EMF measurements of the emissions of each base station can be made at any time at the request of citizens or local authorities.
How can I check Standard Absorption Rate (SAR) of my mobile phone?
There is information about the compliance with the international standards for SAR in the box of any phone purchased from Yettel. Additionally, information about SAR of every mobile phone can be found through FCC ID of the device. Usually, FCC ID is on the sticker with the information about the phone, stuck below the battery. After you find your number, go to the web-page http://transition.fcc.gov/oet/ea/fccid/. Put in the data as it is described and click on “Search”. The information about the SAR of your phone will be displayed. Furthermore, some of the producers of mobile operators present information about SAR on their website, as well as in the guide of the device.
Where can I find additional information on the topic?
You can find additional information about the electromagnetic field emissions of mobile devices and base stations on the following addresses:
