Hi, I live in Switzerland and have been a Sunrise customer for many years.
Up until recently, it was possible to send SMSs online, from Sunrise mail.
But now the whole functionality seems to be gone, including all the contacts :-p
Is this a temporary problem?
On the following page it still says “Sunrise mail: Powerful, free e-mail service for Sunrise customers. Send up to 50 free SMS and MSS messages with the SMS/MMS sender.”
