Once your Smart SIM is installed and configured, it's worth running a quick test to make sure everything is working correctly. This guide walks you through how to do that, both through the Honest app and via our connection test page.
Before you start
For each of the steps below, the quickest way to make changes is through Control Centre, swipe down from the top right of your screen to open it.
1. Turn off Wi-Fi
Open Control Centre and tap the Wi-Fi tile — it should turn grey when off.
Alternatively: Settings → Wi-Fi → toggle off
2. Turn off any VPNs
Skip this step if you don't use a VPN.
Open Control Centre and tap the VPN tile if it's showing.
Alternatively: Settings → VPN → toggle off
3. Switch mobile data to Smart SIM
Open Control Centre, long-press the Mobile Data tile, and select Honest Smart SIM.
Alternatively: Settings → Mobile Service → Mobile Data → Select your Smart SIM
4. Run the connection test
Test in the Honest app
Open the Honest app
Tap your Smart SIM
Tap Test connection
The app will run a quick check and show a success screen if your Smart SIM is connected and working correctly.
