Your account, usage, and billing will live in a dedicated customer portal — separate from this marketing site, so your account details stay behind real authentication rather than a login box bolted onto a brochure page.
Right now: Zephyrline doesn't have active billing customers yet, and the customer portal isn't live. Once it is, you'll be able to view your plan, see your bill, update payment info, and message support directly from your account.
If you're an existing customer with a question about service or an upcoming bill, email or call and we'll sort it out — no portal required yet.
