Then this is the app for you. With this app you can get a good idea of cellular and WiFi signal strength and find out which corners of your office or home are receiving the best reception. Dual SIM has been standardized from Android Lollipop 5.1 onwards. There are still many bugs in manufacturer implementations. If you are experiencing errors related to the dual sim in the app, try the app after disabling the dual sim processing in the app options. Also try to set both calls and data on the same SIM in the Android SIM settings. Consider sending an email to describe the bugs to incorporate alternative solutions.
