EE has revealed how much customers will be paying for 4G broadband - with packages costing up to £56 per month.
Its 4G service will be the first in the UK when it launches on October 30, and the company claims it will offer typical speeds five times faster than 3G.
Fourth generation, or 4G, mobile services will deliver much faster data speeds to phones and other wireless devices, such as tablets and laptops, enabling rapid downloads and live television streaming on the go.
EE is also launching a new fixed-line fibre service for homes and offices, with speeds roughly 10 times faster than current standard broadband plans.
The basic £36 monthly 4G service gives users an allowance of 500MB of data, extending up to 8GB for the £56 plan.
Unlimited calls and texts are standard across all payment packages.
Whichever plan a customer chooses, they will receive a warning text once 80% of their monthly data allowance has been used up, with a further alert once it has all been used.
Users can either pay more to keep themselves online until the next month, or choose to go without.
EE's 4G customers will be able to download or stream one film each week without eating into their data allowance.
Further films can be downloaded or streamed, with prices starting at 79p, and the cost can be charged to a customer's mobile bill, or credit or debit cards.
The EE Film service, which combines 2-for-1 cinema ticketing, listings, trailers and film downloads or streaming, will have more than 700 films available in total at launch.
But technology site Tech Radar pointed out that the films will only be available in standard definition, which it said was disappointing as the 4G handsets feature full HD displays.
However, customers will be able to watch a film on their mobile, on their PC or even on their TV via their laptop.
A Pause & Play feature means they can view the film on one device, such as their smartphone, pause it, then pick it up on another device, such as their laptop.
The launch of the EE brand, called 4GEE, will be backed by a multi-million-pound marketing campaign.
The 4G service will initially be available in London, Bristol, Birmingham, Cardiff, Leeds, Sheffield, Edinburgh, Glasgow, Liverpool and Manchester, with a further six cities coming online before Christmas.
More cities and rural locations are planned for next year, and 98% of the population is due to be covered by the end of 2014.
