If you are on a 4G/LTE network and want to place a call, you may notice that the signal will drop to a 2G/3G network during that call and sometimes you won't be able to use data until you hang out. All of that is solved with VoLTE, which stands for Voice over LTE and translates to the use of the 4G/LTE network to transfer the data of your call and also for SMS messages. Carriers are just beginning to implement that feature and if you happen to live in the UK, know that Three UK is just bringing VoLTE for the country. The service is being branded as" 4G Super Voice" and will offer high-quality voice calls and better coverage for customers.
Three is using its new 800 MHz spectrum that offers a better reception in some low-coverage areas. This frequency also penetrates better indoors so if you have a weak signal at home, things may get better. At launch, the service is going to cover 50% of the indoor population in the UK but the company says that it will expand to 65% in the coming months. "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," said Bryn Jones, CTO of Three UK.
Although Three is the first one to bring it live to consumers, all carriers on the UK are in the process of implementing VoLTE. Both EE and Vodafone are getting ready to implement the technology soon – Vodafone already brought voice over 4G in Australia, Spain and Italy. For now VoLTE will be available for all Galaxy S5. Other devices will need a special software patch to be able to use the technology and the company says these updates will be released as soon as they are ready. VoLTE comes together with Wi-Fi Calling which allows users to switch calls between an LTE network and a Wi-Fi connection without drops, but the company didn't mention anything about the subject.
