Blocking incoming calls on your Sony Ericsson phone is pretty simple. You can go to your service provider's website and follow the instructions they have for call blocking. They will usually tell you how to block specific calls or all incoming calls. You will most likely find a way to even block incoming text messages. This is very convenient if you don't won't to be bothered, but you don't want to miss a possibly important call either. Luckily, with a Sony Ericsson, you don't even have to go to your service provider's web site to block incoming calls. You can do it through your phone's menu.
Flip open your cell phone and go to the phone's menu.
Select "Settings" and scroll down to "Calls."
Select "Manage Calls" and then choose "Accept Calls."
Choose to accept "All Calls," "Calls from a list" or "None." If you choose to accept calls from a list, you will have to create your list of accepted callers. This is easy. You will just scroll through your contacts and select numbers you want to accept.
To stop blocking calls, go to the same menu and choose to accept "All Calls."
