How to Block Unknown Calls on HTC Hero
- 1). Download and install Mr. Number. This free app uses a list to block calls that other people have reported as spammers, and you can use it to block unknown calls. You can choose whether to have the app send the blocked calls to voice mail or to hang up on them. As of the date of publication, an extra paid feature looks up numbers you don't know and tells you who called for $1.99 per month.
- 2). Obtain Call Control. This app also uses a blacklist you can use to block calls that other users have reported. It can also block calls from unknown numbers. You can choose to hang up on the caller or send the call directly to voice mail. The app has a seven-day trial period, after which it costs $7.99, as of the date of publication, for full functionality.
- 3). Use GBlocker, another app capable of blocking calls from unknown numbers. The app does not work off a community list to block calls, so you must manually tell it to block the numbers you want. However, you can use wild cards. For example "1800*" blocks all 800 numbers. The app sends the calls directly to voice mail. As of the date of publication, the app costs $5.68.
