# A message wasn't delivered

Why a message can fail, and what to do about it.

All collections: [Troubleshooting](https://app.ueventi.com/docs/en/troubleshooting)

If messages fail, you'll see a banner on the event page and on the **Activity** tab of the **Guest journey**: "Some messages were not delivered".

## What we do

We retry automatically for three days. While we're retrying, you'll see "will retry". If we stop, you'll see "stopped retrying, contact them yourself".

## Common reasons

- **Wrong number.** Open the guest and check the phone number and country code.
- **The guest doesn't use WhatsApp.** Set their **Preferred channel** to **SMS**.
- **The phone is off or out of reach.** The retry usually catches this.
- **The country has restrictions.** See [Sending to other countries](https://app.ueventi.com/docs/en/articles/supported-countries).

If it matters, call or message the guest yourself. You can send them their personal link with **Copy invite link**.
