Many phones with access to email are now available in the market, and there is no need to spend big bucks to afford a phone with such feature. Given that more people are demanding email on the go, research firm Gartner believes that SMS would soon be a goner.

According to the firm, one of five people will be using mobile email by 2010. 20 million wireless email users today will grow to a whopping 350 million on the same year, said firm's research vice president Monica Blasso. She noticed that the availability of low-cost phones with mobile email functions is driving consumer adaptation.

"Once email becomes available more or less free of charge by default on your mobile handset, people will gravitate to that rather than just continuing to use SMS," added Robin Simpson, mobile and wireless research director at Gartner Australasia. This is due to mobile email access being offered free as part of mobile phone contracts in Australia, he said.

According to Simpson, low mobile email uptake in Australia can be credited to high costs, but competition between carriers like Hutchison 3 and Virgin Mobile will drop prices rapidly. "The interesting thing is that SMS, if you look at it in terms of actual cost for the data, is really expensive, and where we're heading is you'll get a free email package when you sign up to your monthly plan," he continued.
