What is GSM?

GSM is a group mobile experts’ name (French: Groupe Spécial Mobile)
acronym. Later, the meaning of the acronym was changed to “Global System
for Mobile Communications” to facilitate the promotion of GSM to the
world. GSM is the world’s most popular standard for mobile phone
systems. It is used by over 1.5 billion people across more than 212
countries and territories. It differences from its predecessor technologies in that both signaling and speech channels are digital, and thus GSM is considered a second generation (2G) mobile phone system.


The early 1980s, the first generation of mobile phone technology began to use, when the existence of many incompatible standards. The user’s mobile phone
can not use on other network criteria, that resulting in great
inconvenience. Because of this reason, Western European countries began
to consider developing unified next generation mobile phone standards.


In 1982, the European Conference of Postal and Telecommunications
Administrations (CEPT) created the Groupe Spécial Mobile (GSM) to
develop a standard for a mobile phone system that could be used across
Europe. In May 1987 GSM members agreed to determine the GSM of the most
important of several key technologies. In 1989, GSM responsibility was transferred to the European Telecommunications Standards Institute (ETSI). In 1990, the first edition
of GSM standard has be completion. In 1991 the first GSM network was
launched by Radiolinja in Finland with network infrastructure provided
by Telenokia and Siemens Networks which later on merged as Nokia Siemens
Networks. By the end of 1993, over a million subscribers were using GSM phone networks being operated by 70 carriers across 48 countries.


From a user perspective, GSM can provide higher quality digital voice.
From the network operator point of view, them can deploy equipment from
different vendors, because as an open standard GSM provides easy
interoperability.

Parents have to teach responsible cell phone use

Cell phones give kids access to a world that’s both portable and
private. Unlike when they talk on the phone at home, with a cell phone
you’re not there to monitor what they’re saying or sending, or whom
they’re talking to.


Unfortunately, this access means that kids can use these powerful communication tools irresponsibly. They may text when they should be paying attention to what’s going on around them. They may engage in sexting,
by sending or receiving inappropriate pictures or messages.
Embarrassing texts, photos, and videos captured on phones can be sent
instantly or uploaded easily to Web sites. This form of cyber bullying can happen swiftly and anonymously.


A few other things to be aware of: Texting has also led to cheating in class,
as kids noiselessly text answers to one another. Your children may text
late into the night because you won’t hear them. Cell phones can
distract kids from what’s going on around them and can be expensive.
Mobile phones, and the monthly plans that support texting and Web
access, can cost a small fortune.

Press the keys *3370# to activate hidden battery power on your mobile phone.

This "tip" is totally bogus. You cannot activate hidden or reserve
battery power by keying in *3370# or any other code sequence. The code
'*3370#' can be used on some Nokia models to activate Enhanced Full Rate
Codec (EFR). Ironically, since this code activates the best sound
quality on the phone, the change will actually reduce the length of time
that the battery will last before recharging is required – in practical
terms the complete opposite of what the tip suggests.


Entering the code has no effect at all on brands of phone other than Nokia.

Cell Phones and Time Management

Reminders and alarms are some of the most useful tools on a cell phone, but they are also the least appreciated.

Most
cell phones come with a scheduler to allow you to set an alarm at a
certain time of day or on a certain date. You can set alarms to remind
you of an established daily homework time to keep you from chatting
right through your work time. For instance, you can set up a beeper that
goes off every night at 7.

You could also use calendar
reminders to notify you when projects and assignments are due. These
reminders can be set up weeks and months ahead of time.

Quickly repair your Mobile Phone dropped in water

Many of you get your mobile phone wet by one way or another. You worry as you mistakenly drop your mobile phone in water. It can also get wet if you are out in a heavy rain.  However, there is no need to panic. It is possible to save your wet mobile phone by quickly repairing it. In order to save your mobile phone from water damage, you can consider these easy and simple solutions:

Act rapidly :

The first thing you have to do in order to save your wet mobile phone is to act rapidly. Quickly remove all the detachable parts as well as covers possible such as the back cover, battery, the SIM card, memory card etc. Next, take a piece of cloth or a tissue paper to wipe the excess water you are able to notice within the mobile phone. Make sure that you dry it completely. If you don' t do this, the water inside the mobile phone will begin to evaporate and gather in places which will be difficult to reach.

This will save your wet mobile phone and it will start working if it was under water for just a little while.

Using a hairdryer :

Take a hairdryer and begin drying the mobile phone while giving more consideration to the place where the battery is located. The battery housing usually consists of tiny holes to let in air (so giving more space for water) inside the mobile phone.

Make sure that you are not holding the hairdryer very near to the mobile phone. Keeping it too close to the mobile phone may harm the electrical mechanism of the mobile phone. Keep on drying the mobile phone from a safe distance for about twenty to thirty minutes.

If solution number 1 and solution number 2 don't work, try solution number 3.

Drying for a long time:

Take off the covers as well as battery from the mobile phone. Put the phone in a dry as well as warm place to let the water inside the phone evaporate gradually from the little holes in the mobile phone.
