Can I get a number in a specific California town?
Yes. Numbers are tied to a local calling area, so pick the town your customers are in and the number reads as local to them. Oakland, Los Angeles, Modesto have the deepest stock right now. Search above, or open the full search with every town in California.
Can I keep my existing California business number?
Yes. Porting is free, in any volume. Keep the number your customers already know and point it at SimuWave. It can ring desk phones and cell phones at the same time.
How fast can a California number be working?
A new number is live in minutes: choose it, attach a call flow, and it rings. Ports take longer because the current carrier has to release the number, and the number keeps working on the old service until the port completes.
What time zone should I set for California business hours?
California is on Pacific time. Set your business hours once in the call flow, and after-hours calls go to voicemail, an answering service or a cell phone automatically.
