Ratings and reviews

CRASH.CRASH.CRASH Sim Info worked but did not display CID. Device Info (Primary reason I installed) CRASH! CRASH! CRASH! Of course the AD displays just fine before closing the ad and CRASH! CRASH! CRASH! "Unfortunately, Sim Phone has stopped" Battery Info and More Apps works. ---- [edit 1] ---- I forced stopped and cleared cache/data of the app. Then I enabled base GPS. No change. App crashes. Are you saying I have to enable Google location services as well for this to work? If so, why the need for that? --- [edit 2] --- ok, so tried enabling GPS and GLS, forced stopped and cleared cache/data of the app, rebooted, made sure Google Maps found my location, and tried the app. No worky still.

Extremely poor user experience. The Sim information is not working at all. The application is completely unresponsive and displays ads everywhere, making it inconvenient to use. I understand the usage of ads, but this is a development mess.

Very Little details about the device. Not a single thing about the second SIM. The app must be Updated.
