SonyEricsson phones will support internet plus fax. Some Nokias and
Ericssons will too. The question that you will need to ask the service
providers is whether they support fax (AT&T didn't). Also, Fax needs to
be enabled on the SIM.
The the UK Vodafone support SMS messages to a fax machine - I assume
this is what you want to do. This is a prefix to the number that is
dialled to tell the network that you're sending a message to a fax
machine. I believe this is network dependant.
