Gemalto has created the first SIM card to have Facebook functions built in. Gemalto worked closely with Facebook for developing the SIM product and that means that the social network will be able to work with bare-boned handsets. Below is a note from a Facebook spokesperson:
We worked closely with Gemalto on their Facebook for SIM product and believe it will be another easy and affordable way for people to stay connected through Facebook on the mobile phone of their choice. Facebook for SIM creatively combines technologies from some of our existing mobile solutions that especially are attractive for people with feature phones and have limited or no data plans with a mobile operator. Through the Facebook application on the SIM card people can: Update their status and view comments on it; write on their friends wall; receive notifications; find friends on their SIM phonebook.
