Every person who uses email is aware of email spam. Recently, the spammers have taken a huge leap from emails to mobile phones. They have now shifted their focus from email users to cell phone subscribed through text message spam. Some common examples of text message spam include short ads, stock quote and the like.
The spam message cannot be too long as there is an imposed character limit on text messaging. Though these short junk messages do not pose any threat to the consumers, they impose a problem which doesn’t occur with email spam; that is cost. The web users are not charged any money for receiving messages on their email accounts. However, in case of text messaging software, the subscribers have to pay a fee once they cross their allotted limit of calls or SMS.
In the USA, the subscribers have to pay a fixed amount for sending as well as receiving text messages on their phones. This means that the subscribers have to pay money for receiving spam on their phones as well. This can prove to be very harmful for the service providers in the long run as paying unnecessarily for spam can discourage them from using cell phone or text messaging service. Most wireless carriers earn billions of dollars through their text messaging service. Therefore, it would result in a great revenue loss if subscribers stopped using their service.
To avoid this, the wireless carriers are already taking steps such as filters to screen out and curb spammers and junk messages.
