Three’s 4G Super-Voice promises crystal clear calls on the iPhone 6s

Three’s beaten EE, O2 and Vodafone to the punch by becoming the first UK network to launch 4G voice calls, which promise better reception, quality and faster call times. 

Dubbed ‘4G Super-Voice’, a slightly more user-friendly handle than its industry-name VoLTE (Voice over LTE), the new crystal clear calls tech is primed and ready to roll out to a number of high-end phones, including the recently announced iPhone 6s and iPhone 6s Plus

4G Super-Voice is already available to over 50 per cent of the population, according to Three. This includes indoor coverage, a feat which Three is able to pull off due to it’s use of the 800MHz band of the radio frequency spectrum. 

This band was one of the many slices of the airwaves auctioned off by UK telecoms regulator Ofcom back in 2013. It’s situated lower down in the UHF band than other frequencies used by mobile services, which is what allows services on it to travel longer distances and through walls.

The same logic applies; lower frequencies signals are better at penetrating over distances. 

You bedroom walls might not get shaken by 4G Super-Voice, but at least you’ll finally be able to get decent reception there (if you weren’t already).  

Three also plans to upgrade and integrate WiFi Calling later in the year. This will do away with the need to fire up the Three inTouch app, as this functionality will be baked right into the dialler, like it is on selected EE phones now

While around half of the population can start enjoying the benefits of 4G Super-Voice now, Three aims to expand coverage to 65 per cent by 2016 and hopes to get a million customers using the new service. 

Bryn Jones, Three’s chief technology officer, said: “By the end of the year, one million of our customers will have access to better indoor coverage and be able to use their phones in more places than ever before. We are proud to be the first network to roll this out across the country.”

More than three quarters of Birmingham, Edinburgh, Exeter and London are currently covered for 4G Super-Voice and work has begun on bringing the tech to Cardiff, Manchester, Liverpool and Bristol.

As well as being able to reach more people in more places, 4G Super-Voice calls are faster to connect (they’re near instantaneous, in fact) than typical voice calls and also allow for clearer, more audible conversations.

In short, they’re like regular, ordinary voice calls, on steroids.
