Anyone that has a SIM card of any mobile operator in Finland, can
register to eniro.fi service by sending a free SMS to their number.
Then sender gets back a SMS that contains password for accessing their
web site.  After that the user can start sending SMS messages to anyone
in Finland, who has public mobile phone number.  Receivers see the
messages arriving from senders own mobile number and can reply to
them normally.
