Here is a guide on how much texts, calls and internet browsing will now cost in the EU and how to avoid those high phone bills.
A new payment service has been launched. ITV News Consumer Editor Chris Choi looks at its security features.
It has been 21 years since the first text message was sent from a computer to an Orbitel 901 mobile phone.
Mobile phone users whose handsets are stolen will no longer be hit with "shock bills" when a new cap on the maximum value of calls they will be expected to pay for comes into force next spring.
The Government has struck the deal with four major mobile companies - EE, Three, Virgin Media and Vodafone, as well as communications providers BT, Sky and TalkTalk.
It marks the latest move by ministers to help households struggling to pay their bills, following accusations by Labour leader Ed Miliband that the UK is suffering a "cost of living crisis".
Imogen Cauthery was involved in a collision with a driver who was using a mobile phone when she was just nine years old, leaving her with a permanent brain injury.
She told ITV News that how she thinks drivers have a responsibility to always pay attention behind the wheel.
Mobile phones pose a "similar" threat to road users as drunk drivers would and are leading otherwise responsible drivers into "horrific" accidents, a safety campaigner has said.
Brake deputy chief executive Julie Townsend explained:

We're living in an age when being constantly connected is the norm. More and more of us have smartphones, and find it hard to switch off, even for a minute.
While there are enormous benefits to this new technology, it's also posing dangerous temptations to drivers to divert their concentration away from the critical task at hand, often putting our most vulnerable road users in danger.
Many people who wouldn't dream of drink-driving are succumbing to using their phone and other distractions while driving, oblivious that the effect can be similar and the consequences just as horrific.
Over half of all children recalled being driven as the person behind the wheel used a mobile phone, road safety campaigners have said.
According to road safety campaigners Brake:
- A further 79% had spotted drivers on their mobile outside their school or home.
- 575,000 UK drivers have points on their licence for using their mobile phone at the wheel or being otherwise distracted.
- Of these, 6.5% have totted up six points or more;
Hands-free sets should be banned and drivers should turn off their mobile phones when getting behind the wheel, a road safety group has said.
Charity Brake want to see drivers focus more on the road by abandoning hands-free sets and are using the start of Road Safety Week to persuade road users to turn off their mobiles.
Brake are also urging everyone not to speak on the phone to someone who is driving.
Canada's Minister for Employment Jason Kenney has said he sympathises with employees of phone company BlackBerry, after it announced it would cut around 40% of its workforce. Canada is one of the countries that manufactures the phone.
Sorry for the good people @blackberry who will be affected by downsizing. I'm confident that such brilliant folks will land on their feet.
Phone company BlackBerry could survive as a much smaller player, an analyst has told Reuters, after it announced that it would cut around 40% of its global workforce.
BGC Partners analyst Colin Gillis said: "This is the end of the BlackBerry as we know it.
"This is a major pivot. They are cutting half of their employees and they're going to focus on becoming a niche player focused on the enterprise."
He added: "The company has sailed off a cliff...What do you expect when you announce you're up for sale? Who wants to commit to a platform that could possibly be shut down?"
The Ontario-based company BlackBerry said it expects that its adjusted net loss, will be in a range of about $250 million to $265 million (£165.4m) or a loss of 47 cents to 51 cents per share.
BlackBerry said it expects to report revenue for the second quarter of about $1.6 billion, of which roughly 50 per cent is expected to be revenue from its services unit.
The company said it plans to refocus its efforts on the enterprise and high-end consumer markets, offering end-to-end solutions, including hardware, software and services.
