Just to give an update to others looking for *DSL a couple of years later:
- Swisscom will provide ADSL without fixed telephone line - provided that you subscribe to their mobile (keyword: NATEL). Mobile monthly fee starts at 26 CHF, fixed tel. at 25.xx. What a coincidence.
- Price for ADSL (VDSL) is currently (2010-08) 69 CHF/m for the fastest home customer line on top of the line fee. Basic symmetric DSL is only available through business services, and at something like 2Mbps it didn't really fit the bill for me. (If anyone knows of faster DSL, symmetric or not, do drop a line. 24 Mbps is sort of a bummer, what with 100M and 1G connections out there in the wide world.)
- Got really helpful, prompt, and efficient service at Swisscom phone service, made my day. (Old tenant hadn't released their line; customer service clarified the matter, redirected the old customer, and proceeded to set me up with a line. The modem and the bill should arrive by post this week, and the line should be already up. We'll see if everyday service keeps up with new customer enticement...
