Real evenings. Real weekends. A real off-hours.
The work line rings during work hours. After 6 pm, it's silent — calls route to voicemail with a custom "I'll return your call Monday" greeting. Holiday calendar handles long weekends. Lock-screen DND on the Kelir line while personal stays live. The promise of every business-line product, but actually delivered.
What this is solving for.
Every business-line product promises a real boundary between work and personal. Most don't deliver. Softphone apps require you to actually quit the app to silence work calls — and you forgot to last Tuesday, so a client got through during dinner. Personal cell with a forwarded business number means clients see the personal cell on call display and start texting it for everything. Generic voicemail-only "after hours" feels like the line is dead, which feels unprofessional for an active business.
What a solo professional actually wants: the work line behaves like work hours during work hours, and like a closed office outside work hours. Customers who call after 6 pm hear a professional after-hours greeting, leave a voicemail, get an email transcript so it can be triaged tomorrow, and the line itself goes silent on the user's phone. No app to remember to mute. No personal cell exposed to clients. The personal line stays live for personal calls.
Kelir Solo handles this exactly because the eSIM model makes it natural. The work line is a real cellular eSIM, separate from the personal SIM. Working-hours rules apply at the routing-platform level — outside hours, the eSIM doesn't ring at all. Voicemail captures with email-delivered transcript. The personal SIM is unaffected; personal calls keep coming through.
Features that apply.
Kelir Solo at $24.99/mo bundles the full single-user feature surface, working-hours rules included. No upgrade required for the boundary.

Do-not-disturb
Lock-screen DND on the Kelir line while personal SIM stays live.
Step by step.
- Step 01
Set per-day working hours
Kelir mobile app → Settings → Working hours. Mon–Fri 9–6 ET. Sat–Sun closed (or partial weekend hours if applicable). Tap any day to edit independently.
- Step 02
Mark the year's holidays
Memorial Day, July 4, Labor Day, Thanksgiving + Friday after, Christmas Eve, Christmas Day, New Year's Day, Martin Luther King Day, Presidents' Day. Optionally add personal long weekends as one-time entries.
- Step 03
Compose the after-hours greeting
Auto-attendant after-hours greeting: "Thanks for calling Sarah Chen Consulting. I return calls Monday through Friday between 9 and 6 — please leave a message with your name and number, and I'll call you back tomorrow."
- Step 04
Configure the routine path
Default after-hours behavior: route to personal voicemail. Email transcript delivered automatically when a message comes in.
- Step 05
(Optional) Configure an emergency path
For true emergencies, add an option to the after-hours greeting: "If this is urgent, press 1." Press-1 routes to a paging-service number or a covering colleague's personal cell.
- Step 06
Set lock-screen DND on the work line
iOS/Android lets you configure ringtones and DND per cellular line. Set the Kelir line to silent ringtone after-hours so even if it did ring through, the lock screen stays quiet.
- Step 07
Test by calling from another phone
Outside work hours, call your Kelir number from a friend's phone. Confirm: greeting plays, voicemail records, email transcript arrives, your phone doesn't ring on the work line, your personal line is unaffected.
What changes.
- Work line goes silent at 6 pm — real boundary, not aspirational.
- Customers hear a professional after-hours greeting that sets clear expectations.
- After-hours messages arrive as email transcripts — triage from the lock screen, decide what's worth a Saturday callback.
- Personal line stays live; family calls and personal-life logistics keep working normally.
- Holiday weeks run unattended — set the year's holidays in late October, ignore them the rest of the year.
- Long weekends and personal vacations: add to the holiday calendar as one-time entries, runs once, reverts.
The right buyer.
Solo professionals who want a real work-life boundary on their phone: consultants, coaches, executive trainers, therapists in solo practice, freelance creatives, financial advisors, single-agent realtors, solo contractors, executive assistants for a single principal. The user is the only person on the line; clients call expecting the user to handle it personally; the user wants evenings and weekends mostly off-limits without going completely silent.
Who this isn't for: If you're available 24/7 by design (high-stakes practice, on-call medical specialty, emergency-services provider) and customers expect to reach a real person at 11 pm, working-hours boundary isn't your use case — your phone should always ring through. If you have a small team rather than just yourself, look at after-hours coverage with on-call rotation — that's the team-version of this same problem.
Common questions
Both. The Kelir routing platform evaluates the schedule before ringing the eSIM. Outside working hours, calls don't ring through to your phone — they route directly to whatever you configured (voicemail, optional emergency forward). Your phone doesn't ring on the Kelir line. The personal SIM is unaffected; personal calls keep ringing.
Either set wider working hours (e.g. Mon–Sat 8–8) or configure an emergency option in the after-hours greeting ("press 1 for urgent matters — connects to my paging service"). Most solo professionals settle on one of these patterns. If clients truly expect 24/7 availability without exception, your service-level expectations are different from the working-hours-boundary use case.
Add the days as one-time entries in the holiday calendar. The system uses the holiday-specific behavior (typically a longer-greeting voicemail with promised callback Monday). After the weekend, the schedule reverts automatically.
Yes. Per-day schedules: Monday 9–6, Saturday 10–2, Sunday closed. Tap any day in the working-hours config to edit independently.
Standard email with the transcript text in the body, audio attached, sender from your Kelir voicemail address. iOS/Android lock-screen previews show the transcript text — "Hi this is Jen calling about the Tuesday meeting…" — readable in 2 seconds without opening the email.
No. Modern iOS/Android lets you configure ringtones and DND per cellular line independently. Set the Kelir line to silent or DND-active outside hours; the personal SIM keeps its normal ringtone and behavior. Personal calls ring; work calls don't.
