Today, two popular British carriers O2 and Vodafone have officially launched their much-anticipated 4G LTE services in the U.K., at last bringing an end to EE’s effective monopolization. O2 4G is accessible in London, Leeds and Bradford, whilst Vodafone LTE is confined to just London at present.

Now that EE is already providing 4G LTE services in the U.K., and Vodafone and O2 are scheduled to launch their own 4G networks at the end of this month, Three was the only major carrier yet to announce its rollout plans.

But the company has today confirmed that it is on track to launch 4G during the fourth quarter of this year, and that it will come at no extra cost to consumers.

O2 has today confirmed the price of its 4G price plans ahead of their rollout next Thursday, August 29. The carrier’s SIM-only plans will start from £26 ($40) per month, while those that are tied to a 4G handset start from £32 ($49) per month. All of O2’s 4G plans will also come bundled with free music, sport, and game content.

HTC’s latest One variant, the One Mini, is now available to purchase from Vodafone U.K., just a fortnight ahead of the carrier’s scheduled 4G switch-on.

Vodafone U.K. has today announced that it will begin rolling out its new 4G network on August 29 — the same day rival O2 will launch its own 4G service. The company will reach 12 major cities across the country initially, with further expansion planned before the end of this year.

That means that by the end of this month, EE will no longer be the U.K.’s only 4G provider.
