# No signal

> What to do if you lose internet connection at market.

If you lose signal at market, Shopify POS will not be able to process payments until your connection is restored.

## If you lose signal

1. Check that cellular data is enabled on your phone (not accidentally switched to airplane mode)
2. Move to a location with better signal if possible
3. Connect to a mobile hotspot from another device
4. Once reconnected, you can continue selling normally — no data is lost

## Before market day

Set yourself up for success before you leave:

* Confirm you have signal at your usual market location
* Bring a portable hotspot or enable your phone's hotspot as a backup
* Run a test sale at home on WiFi before your first market day

## Sync your catalog before you go

If you edited products before market, open PopUp once on WiFi and tap **Settings → Sync Now** to push those changes to your device before you leave.
