the first mobile phone with internet connectivity was the nokia 9000 communicator, launched in finland in 1996. the viability of internet services access on mobile phones was limited until prices came down from that model, and network providers started to develop systems and services conveniently accessible on phones. ntt docomo in japan launched the first mobile internet service, i-mode, in 1999 and this is considered the birth of the mobile phone internet services. in 2001, the mobile phone email system by research in motion (now blackberry limited) for their blackberry product was launched in america. to make efficient use of the small screen and tiny keypad and one-handed operation typical of mobile phones, a specific document and networking model was created for mobile devices, the wireless application protocol (wap). most mobile device internet services operate using wap. the growth of mobile phone services was initially a primarily asian phenomenon with japan, south korea and taiwan all soon finding the majority of their internet users accessing resources by phone rather than by pc. developing countries followed, with india, south africa, kenya, the philippines, and pakistan all reporting that the majority of their domestic users accessed the internet from a mobile phone rather than a pc. the european and north american use of the internet was influenced by a large installed base of personal computers, and the growth of mobile phone internet access was more gradual, but had reached national penetration levels of 20–30% in most western countries. the cross-over occurred in 2008, when more internet access devices were mobile phones than personal computers. in many parts of the developing world, the ratio is as much as 10 mobile phone users to one pc user.
history of the internet
in some countries, text messages can be used to contact emergency services. in the uk, text messages can be used to call emergency services only after registering with the emergency sms service. this service is primarily aimed at people who, by reason of disability, are unable to make a voice call. it has recently been promoted as a means for walkers and climbers to call emergency services from areas where a voice call is not possible due to low signal strength. in the us, there is a move to require both traditional operators and over-the-top messaging providers to support texting to 911. in asia, sms is used for tsunami warnings and in europe, sms is used to inform individuals of imminent disaster. since the location of a handset is known, systems can alert everyone in an area that the events has made impossible to pass through e.g. an avalanche. a similar system known as emergency alert is used in australia to notify the public of impending disasters through both sms and landline phone calls.these messages can be sent based on either the location of the phone or the address to which the handset is registered.
