Data stopped mid-trip with no warning

Check first

Open the KnowRoaming app and go to My plans. Check the plan's status, the data left, and the days left. Then check which country you're in against the plan.

Causes, in order

The data is used up

A fixed plan stops at zero while the bars stay full. Tap Top up and the new balance applies straight away, on the same eSIM. See Top up your plan: add data or days without a new eSIM. An unlimited plan doesn't stop; it slows after its daily allowance.

The days have run out

Validity counts from the moment you first connected, and the plan shows as expired in My plans. If the trip ran longer than the plan, top up with days where the plan allows it, or add a new plan for the same destination.

You crossed into a country the plan doesn't cover

Common on land borders and cross-border trains. A country plan covers one country; a regional plan covers its list. Add a plan for the country you're in from the app on any Wi-Fi; it goes onto the same eSIM. See Crossing into a border country your plan doesn't include.

Your phone moved data back to your home SIM

Restarts and updates can do this, and iPhone's Allow Cellular Data Switching can do it on its own. Set data back to the KnowRoaming line; see Phone reverting to the home SIM automatically.

The network has a problem where you are

Less common. If people around you have lost signal too, it's local infrastructure, not your plan. Give it time, or switch networks manually if another is available.

Still stopped with data and days remaining, in a covered country, on the right line? That's the one we need to look at from our side.
