I look for a VoIP provider which allows short messages

Good evening,

I want to use Asterisk for phoning, short messages and fax and look for a VoIP-provider (I want to use VoIP!) who allows these functionalities.
I come from Germany and now visited about 30 different VoIP-companies non of which allows to receive short messages via SIP.
Does someone know a provide which allows these functionalities?

Thank you very much for your help.
