Calls aren't working.

This can happen for a few different reasons (Wi-Fi connection, Quiet Hours, allowed contacts, or carrier blocking). Start with the sections below that best match what you’re seeing.

My Tin Can seems offline (or won’t ring).

Try these steps in order:

1. Move your Tin Can closer to your Wi-Fi router (even temporarily) and try again.

2. In the Tin Can app, update your Tin Can’s Wi-Fi settings (even if you’re staying on the same network). This refresh can help it reconnect cleanly.

3. Try connecting your Tin Can to your phone’s hotspot (internet sharing) as a test.
   If this works on a hotspot, the issue is very likely your home Wi-Fi (not the Tin Can).

4. If you’re on hotel/airport/public Wi-Fi that makes you “sign in” or accept terms in a browser, Tin Can won’t be able to connect to that kind of network.

If none of that helps, use the “Calls drop or sound choppy” section below—some of the Wi-Fi fixes there can help even if the main symptom is “offline.”

Are Quiet time / Quiet Hours / Do Not Disturb blocking calls?

If calls aren’t going through (especially at certain times), Quiet time / Quiet Hours is often the cause.

Try this:

1. Open the Tin Can app and look for Quiet time (shhhh mode) on the home screen. Toggle it off, then try calling again.

2. If you use Quiet Hours schedules, open the app → Manage availability and confirm the hours you set.

3. Double-check your time zone in the app: open the app → Account (bottom bar) → Edit (top right) → choose the correct time zone.

Calls work with some people but not others.

This usually points to one of these:

• The number isn’t on your allowed contact list (or it was entered wrong).

• Your Tin Can number is being flagged as spam by a carrier or spam-filtering app

Start with “Make sure the number is allowed” below, then check “Scam Likely / blocked” if the allowlist looks correct.

Make sure the number is allowed (and not misdialed).

If a number isn’t on the allowed contacts list (or it’s off by a digit), Tin Can won’t be able to call it.

Try this:

1. Confirm the exact number you’re trying to call, then confirm that exact number is on your allowed contacts list.

2. If the contact you added is the wrong number, delete it and re-add it

3. If you’re calling another Tin Can: make sure both people have accepted the contact request—calls won’t work until it’s approved on both sides.

If they’re on your allowed list and it’s not a misdial

This can happen when carriers (or spam-filter apps) incorrectly flag a Tin Can number as spam—especially if calling works with some numbers but not others.

Try this:

1. Make sure your Tin Can’s phone number is added to the other party’s phone’s contacts.

2. If the person you’re trying to reach uses spam-blocking apps (like AT&T ActiveArmor or similar), add your Tin Can number to their “allowed” list (or turn blocking off temporarily to test).

3. If it’s still blocked, contact Tin Can Support. We can submit updates to help carriers treat the number as trusted—this can take up to 48 hours. If it still isn’t fixed after 48 hours, we can assign a new number.

Calls drop or sound choppy.

This is usually Wi-Fi strength or Wi-Fi speed near the Tin Can.

Try these steps:

1. Move the Tin Can closer to your router and test again.

2. Stand near your Tin Can with your phone, turn cellular off (so you’re only using Wi-Fi), and run a speed test. If download speed is under ~50 Mbps, that can cause call issues.

3. If you have Wi-Fi extenders, unplug them temporarily and test with the Tin Can close to the main router.

4. As a quick “reset” for call connectivity, unplug the Tin Can, plug it back in, and wait about five minutes before testing again.

If none of this helps, contact Tin Can Support and tell us: (1) whether the issue is all calls or only some numbers, and (2) whether the Tin Can is close to the router when testing.
