The service is only available on certain phones (and the selection is even more limited if you didn’t buy direct from EE), but many of the latest and most high-profile handsets are supported. We’d imagine that eventually call support will be added to the UK’s 5G networks, especially as it is a use case that has been explored during the development of 5G, but there’s no current indication of when that will happen – right now the focus of networks is understandably on increasing 5G coverage. As you don’t have to switch to 3G when making a call with VoLTE, that means you can also keep using 4G for other functions on your phone while on a call. VoLTE: Although it sounds complicated, VoLTE is simply ‘voice calls over 4G LTE network’ and 4G LTE is today’s fastest connection available for wireless networks. Smartphone users could also find their battery life increased with VoLTE, as without it whenever you make or receive a call your phone has to switch from 4G to 2G or 3G, since 4G calls aren’t supported, and then once the call is finished your phone switches back again. In fact you may have noticed that Skype and other existing video call services often seem to have superior audio quality to voice calls. Since WiFi connects to broadband, most broadband plans allow for data transmissions exceeding 100 GB. If you have a compatible phone, add it with just a couple of clicks at no additional cost.

It's simple to call and simple to use on Verizon’s 4G LTE network. A video call uses approximately 6 MB of data per minute. VoLTE is important for network operators, vendors, original equipment manufacturers (OEM) and consumers. Connecting to WiFi provides a sense of professionalism with clear, high-quality calls that don’t drop. WiFi calling is preferred because saving data is paramount. BT Mobile offers 4G Calling in the same places as EE, so again, it’s widely available, and it works with any iPhone from the iPhone 6 onwards, as well as a number of Android phones. That’s because like VoLTE they use more data as part of a similarly named VoIP system, so you can expect your voice calls to sound more like Skype calls when using VoLTE, but they won’t hit your battery life as much as Skype does. There are several ways to track your data. VoLTE calls will not consume any data. You just have to recharge your phone with normal calling plan and you an avail this service.

All that switching, plus the need to search for a different signal each time, can give the battery a significant hit.

AT&T calls this “HD Voice,” and like T-Mobile, will block voice and data service for phones that don’t support it. Vodafone says that all its existing plans will support VoLTE service. VoLTE calls are usually charged at the same rate as other calls. The voice portion is billed as a standard voice call, according to your plan.

Businesses often have larger broadband data caps. Mobile phone services make it easy because data is critical for any mobile plan today. Furthermore, WiFi calls are often clearer, higher quality, and are more reliable than similar calls on mobile networks. Verizon claims that the average 1-minute video call uses approximately 6 to 8 MB of data. This is helpful for managing data when WiFi is not readily available. The needs of a voice call – clarity, reliability, and immediate connection upon dialing – get lost in the shuffle, if this prioritization is not in place. However, it’s worth noting that at the moment RCS is only used for messaging, and even then not by every network or smartphone maker – with Apple for example not yet supporting it, so this potential of VoLTE hasn’t yet been widely explored. Therefore, adopting and implementing a VoIP solution and WiFi network for calling is a great way for business to cut costs while also increase quality. will not work. A large number of phones are compatible if bought direct from Three including the Samsung Galaxy S20 range, iPhone 11 range, Samsung Galaxy S10 range, Huawei P30 Pro, Xiaomi Mi Mix 3 5G, iPhone X, iPhone 8, Samsung Galaxy S8, Samsung Galaxy Note 8, LG G6, Sony Xperia XZ Premium, Huawei P10 and many more. This is why many users end up with data overages.

If the term "VoLTE" looks familiar, that's because it's similar to VoIP, or Voice over IP, which is making calls over the Internet. Today’s best VoIP systems implemented over WiFi prioritize the transmission of voice packets over data packets. Up to three times as much data as 3G and up to six times as much as 2G to be precise, making it easier to make out not only what the person on the other end of the line is saying, but also their tone of voice. Once on VoLTE, the call can then in turn drop from LTE to 3G. All in all, WiFi calling is clearly more cost effective than data availability and usage. VoLTE has up to three times more voice and data capacity than older 3G UMTS and up to six times more than 2G GSM. We all know that today’s mobile phones are equipped with WiFi technology; therefore, a natural solution for mitigating VoIP call data usage and overages is connecting to Wi-Fi whenever—and wherever—possible. The problem with Voice over LTE is that 4G LTE is a data-only networking technology, so it doesn’t natively support voice calls. VoLTE means HD Voice calls it’s better and clear than normal call and it uses your device data for better call quality These both are so different, so there are so many devices that actually supports 4G LTE but don’t support VoLTE. As detailed in this blog, the increased functionality provided by WiFi gives professionals greater flexibility. The big advantage of VoLTE is that call quality is superior to 3G or 2G connections, as far more data can be transferred over 4G than 2G or 3G. Gaetano DiNardi is the Director of Demand Generation at, We all know that today’s mobile phones are equipped with WiFi technology; therefore, a natural solution for mitigating, The answer from nearly every prominent mobile phone provider is, One of the best ways to make sure this process is done correctly is partnering with a trusted partner in this field.

VoLTE calls use Sprint’s LTE network instead of our traditional wireless voice network. VoLTE stands for voice over LTE and it’s more or less exactly what it says on the tin. Being able to use data while on a call; Place and connect a call faster; Another major benefit of using VoLTE is that a call will not drop if you disconnect from a Wi-Fi signal should you have Wi-Fi Calling enabled. This needs to be seamless or the call will cut out, so it requires masts to pre-emptively deliver a 3G signal whenever the 4G signal drops dangerously low, but also to keep the 4G signal running at the same time, so it can either stay on 3G if it loses the 4G signal entirely or drop the 3G if the 4G signal becomes strengthened again.
