If you use Twitter and are a Bell Mobility customer, there is some great news for you. You now have the ability to update Twitter via SMS as well as receive Twitter updates on your mobile phone. To date, the two-way Twitter service had only been available in the United States.
There are no limits or fees beyond your regular Bell SMS plan fees.
To activate your phone to Twitter over SMS, see the Devices page on your Twitter account.
There is word yet on whether Rogers and TELUS will follow suit but Twitter is working on extending this service to additional countries.
