Unfortunately, the case tore and is no longer usable. Being a device made by BBK Manufacturing, coverage may be limited. In the short time that I've owned it I have only used it on WiFi.Rather than looking deeper into carriers and coverage I've moved on and bought something else and have no need for this. I will try to answer any questions you may have about the device. The item "Vivo Nex Dual Display" is in sale since Friday, March 12, 2021.
