It has been 21 years since the first text message was sent from a computer to an Orbitel 901 mobile phone.
Hands-free mobile sets should be banned and people should turn off their phones while driving, according to a road safety group.
The outgoing Microsoft boss says today's deal with Nokia is "win, win" for both firms - but what about their customers?
Microsoft has agreed to buy "substantially all" of Nokia's mobile phone business at a cost of 5.4 billion euros (£4.6bn).
The deal, which is still subject to approval by Nokia shareholders and regulators, reportedly includes licences to the Finnish company's patents.
Nokia partnered in 2011 with Microsoft and uses Microsoft's Windows software to run its mobile phones.
Phone company Three will attempt to make up for its late entry into the 4G network battle by offering customers an upgrade to the high-speed service for free.
The company said a "simple software upgrade" would be made available "at no extra cost" upon its launch in London, Birmingham and Manchester in December.
The service will be available in 50 cities by the end of 2014.
Like rivals Vodafone and O2, who launched 4G services today, and high-speed frontrunner EE, the company's reach will grow to 95% of the UK by the end of 2015.
Guy Laurence, chief executive of Vodafone UK, has predicted a swift take up for 4G as people crave faster downloading speeds to enjoy music, videos and live streaming.
"I think adoption will be far faster than 3G, which was 10 years ago, because people didn't really know how to use it," he said.
"It is no good trying to sell technology to people, you have to sell something they want, and they want entertainment."
Mr Laurence said 4G will be on tap for nearly all of Britain within 18 months.
"By the end of 2015 we will have 98% coverage," he said. "To give you an idea, only 98.4% of dwellings have running water. So 98% is very high indeed."
EE has had a 10-month headstart on phone rivals Vodafone and O2 after winning the right to launch 4G coverage in the UK.
EE's mobile internet service began in October and now covers 60% of the UK population.
The phone company yesterday crowned Accrington in Lancashire the 100th town in Britain to receive the "super-fast" service.
While today's launch of 4G services by O2 and Vodafone will be limited, both aim to have 4G network coverage in 13 cities by the end of the year and eventually serve 98% of Britain.
O2's service will initially be switched on in London, Leeds and Bradford, reaching up to five million people. Vodafone will roll its service out in parts of the capital.
The phone companies will then expand to London, Birmingham, Bradford, Coventry, Edinburgh, Glasgow, Leeds, Leicester, Liverpool, Manchester, Newcastle, Nottingham and Sheffield.
Vodafone and O2 go head-to-head today as they both launch high-speed 4G mobile phone data services.
Vodafone will offer 4G to its customers in London, while O2 launches its service in London, Leeds and Bradford.
The mobile giants will compete against EE, which has been the only company offering super-fast mobile data in the UK.
The cost of using a mobile phone abroad will be slashed from tomorrow under the new rules. A price cap on downloading data means looking at maps, checking emails and sending pictures while travelling in EU countries will be 36% cheaper, and 91% cheaper compared to 1997.
The new roaming regulations also mean charges for making a phone call will drop by at least 17% per minute while receiving a call will drop by about 12% a minute.
The cost of a text message will fall by 11%.
More than 20 million passengers miss bus or train stops each year because of "digital distraction" from their smartphones, a study has found.
The problem has affected 51% of Britons and causes around 15% of commuters to run late for meetings, according to the findings.
Over the last year, passengers have missed their stops an estimated 29 million times, the report showed.
Londoners were found to be among the most preoccupied by their mobiles. Three in five (62%) of the capital's Tube, bus and train travellers said they missed a stop for this reason.
On average, Londoners miss two stops a year. A handful of commuters consulted for the study (3%) said they failed to disembark at an intended point more than 20 times in the last 12 months.

Mobile phones are making it increasingly difficult to rest in peace with almost a fifth of funerals interrupted by obtrusive ringing, according to research by The Co-operative Funeralcare.
A survey of 2,000 people found that two in five people do not turn their phone off during a funeral service and a small percentage of mourners refuse to turn down the volume.
One in 16 people admitted to accidentally receiving a message on their phone during a funeral while one in six said they had seen others trying to frantically turn off a ringing phone.
Examples included the tune If You're Happy And You Know It Clap Your Hands blaring as a coffin was lowered in South Wales and a vicar's mobile ringing as he gave a eulogy in North Wales.
A separate survey of 170 funeral directors by The Co-operative Funeralcare found that almost a fifth of funerals had been interrupted by mobile phones.
