The possibility of using two SIM cards in smartphones simultaneously is increasingly a requirement for manufacturers. More than having a personal card and another to work, there is now a need to have one card to receive calls and another to access the Internet. But currently, 4G smartphones on the market allow just the primary SIM card to support VoLTE, while the secondary card can only use 2G/3G, which diminishes the calling and internet browsing experience. And In some regions 2G/3G spectrum is being “re-farmed” and some operators are exclusively 4G-LTE only.
Recently, UMIDIGI has introduced three smartphones, the Umidigi A1 Pro, Z2 and Z2 Pro, where it has clearly highlighted its support for Dual 4G VoLTE technology, even launching a video where it is possible to see it acting. Note that 4G VoLTE support is depended on your internet carriers.
VoLTE technology, which means Voice over LTE, which is no more than a voice service over the LTE network, which was initially only designed for data. In the video you can see a very important detail: in a smartphone with Dual 4G VoLTE, in case it is downloading and receiving a call (both to use 4G), nor the download is interrupted, nor the call is compromised.
