Mobile phones started life as the two way radio, which was also called mobile rigs. these were installed in vehicles such as minicabs, police cars and ambulances, but were not strictly mobile phones as they were not normally connected to the telephone network. while the very first mobile phones were installed permanently in vehicles, later versions such as the transportables, also called bag phones, could also be carried, and can be used as either portable or as mobile two-way radios.
The first generation of mobile phones are often called 1G. These mobile phones are the analog devices that were introduced in the eighties & continued until being replaced by 2G mobile phones, which ran on digital networks. in fact, even though 1G & 2G systems use digital signals to connect the radio towers to the rest of the telephone network, the voice itself during a phone call encoded to digital signals in 2g while voices on 1G phones aren’t.

These included text messaging, which became possible on gsm networks initially and eventually on all digital networks. the earliest machine-sent message was sent in 1991 in the uk. the earliest person to person sms text message was sent in 1993 in finland. sms text messaging soon became the preferred method of communication and the public now prefer sending text messages to placing voice calls.
3-g is the term applied to the third generation of mobile phone standards & technology. 3g follows 2g mobile phone technology.
The birth of 3-g technologies allow network operators for instance Vodafone give their users a larger range of more advanced services. These include video calls& wireless internet.
Even though 3-g was successfully introduced throughout the world, issues have been raised by both 3-g providers & users, comprising of costly phones. in addition to this, there’s numerous differences in the licensing terms.
