Getting a "no SIM" error after landing

Check first

Give your phone a minute to connect once you land. Still nothing? Switch on Airplane Mode for 30 seconds, then switch it off again.

Causes, in order

Airplane Mode is still on

Turn it off, wait 30 seconds, and let the phone find a network.

The line is switched off

A line added with "Turn On This Line Later" stays off until you turn it on. On iPhone: Settings > Cellular > your KnowRoaming eSIM > Turn On This Line. On Samsung: Settings > Connections > SIM manager > turn the KnowRoaming eSIM on. On other Android phones: Settings > Network & internet > SIMs > your KnowRoaming eSIM > Use SIM.

The phone hasn't registered yet

Restart it. On Samsung, "SIM not provisioned" or no service right after adding is common, and a restart clears most of it.

Data roaming is off

Once the line is on, turn on Data Roaming for it and select it for data. The taps are in Turn on data roaming for your plan on iPhone, Turn on data roaming for your plan on Samsung, and Turn on data roaming for your plan on Android.

The KnowRoaming line isn't in Settings at all

If your SIM list shows no KnowRoaming line, the plan was removed or never finished adding. Open the app, go to My plans, and check whether your plan shows under your device. If it does, don't try to add it again yourself. Message us first with the details below and we'll check whether it can be reissued.
