A strange thing happened three days before, I can’t call my girlfriend with the short phone number (a service that calling each people who set in a group for free with month payment in China), the phone just one beep then hang up, but I can call her with the original phone number. I have try restart both her and my phone, make sure there is full network signal, but still no luck, everybody can call her except me. This morning I sit down and thinking about the reason, suddenly I get an idea, it is the blacklist phone call.
How to remove phone numbers from phone call blacklist? where is the blacklist in CyanogenMod? it is here: back to Home, press Menu, touch Settings, touch Call Settings, touch Blacklist, then you can see the phone numbers which have been blacklisted, long touch the phone number which you want to unblacklist, now you can remove it from blacklist.
This is for Android phone users who have installed CyanogenMod. you make ask why the phone number was blacklisted without people noticed, I rather to say it is so easy to blacklist a phone number in CyanogenMod, you just need to long press the hang up button when making a call with someone, a window will jump up to ask you whether add this number in blacklist, the thing is the “OK” button is too close to the hang up button, and many people could press “OK” button by mistake even he doesn’t notice, so next time you should hang up calls carefully.
Next time before you are yelling Why I can’t call my girlfriend or wife, check out if she blacklist you by mistake. It is not her fault.
