If you want to receive your friend’s tweet as an SMS, you first need to go to their profile page in twitter. There you’ll see an ‘mobile phone’ icon near to the ‘Following’ label. Click on that icon to start receiving that persons tweets directly to your mobile.

//the ones addressed to you @VRAA//
As of now I don’t know how to receive these tweets as SMS. When I get a direct message, that comes to me as SMS, but when someone mention my twitter handle, that’s not coming to my mobile. Even I’m in a need of this feature.

have you been able to receive any tweets via SMS? those of the people u follow or the ones addressed to you @VRAA. I can tweet, but not been able to get anything back.

Thanks,
Renjith
