I would like to be able to check my SMS messages online. Is this possible? Is there absolutely any other way of checking SMS messages other than having the mobile phone turned on and in the coverage area?
Junjie is right. This has more to do with the software on your phone right now, so it really depends on what you're using. If you're using an iPhone, Android, or Blackberry, I would check out some of their support sites to see if there is a solution that will work for you.
