I have a problem with my HTC one x.. I have a pin set on the SIM card which I enter as soon as I power on the phone... The problem is that sometimes I unblock the phone to use it and I find it one the PIN screen, as if the SIM was reset... Does it happen to any of you? May it be a software bug or a hardware bug related to the SIM tray? I've written to the support to notify the problem and make them consider it for future fw releases and they answered me telling me how to remove the PIN from the phone O_o
It is quite annoying since if you do not unblock the phone you risk to miss some calls and sms if the SIM gets blocked... I hope I won't need to send it to HTC...
I've just published my first android application, SIM Locked Notifier, which enables you to activate a ringtone or vibration (or both) when PIN/PUK is required. In this way you avoid missing calls or messages when your phone is out of the network, waiting for a PIN.
Get SIM Locked Notifier on Google Play!
I hope you find it useful, yesterday it warned me two times about this PIN issue (I'm happy because my app works, but I'm worried about this issue... hope they solve it soon).
The app is not heavy, it does nothing until the SIM State changed broadcast event is fired and the state is PIN/PUK required.
REMEMBER: run the app at least once after installation to enable the SIM Locked Notifier monitor. You must do this only once after installation, then it works even after a reboot.
