The easiest way to install, set up and test your Smart SIM is through the Honest app.
Simply open the app, tap your Smart SIM, and select 'Set up SIM' to be guided through the process.
Prefer to do it manually? Follow the steps below.
1. Install your Smart SIM
This adds your Smart SIM to your iPhone so you can start using it.
Open the Smart SIM email with the subject line 'Your Smart SIM is here 📧' — check your spam folder if you can't find it.
Scan the QR code in the email using your iPhone's camera, or use the manual installation details at the bottom of the email.
Tap Add Mobile Plan when prompted.
Follow the on-screen steps to complete installation.

2. Select "Home"
When asked, "Where will you use this eSIM?", choose Home.
Your Smart SIM will then show up as "Mobile Data" in your phone's settings, with no phone number attached.
3. Locate & label your new SIM
Go to Settings › Mobile Service, and find the new SIM in the list, it's the one with no phone number, probably called "Mobile Data" but sometimes "Business", "Personal", or "Travel – BICS".
Make sure it's turned On.
iPhones only support two active SIMs at a time, so if you already have two others active, turn one off first.
Tap the new SIM › Custom Label, enter Smart SIM, then tap Continue to save, this makes it easy to tell your SIMs apart.
4. Turn On Data Roaming
Scroll down and toggle Data Roaming on, the toggle should turn green.
5. Verify setup & test
Open the Honest app and tap your Smart SIM. You'll see Test Connection as an option.
The app will walk you through three checks: turning Wi-Fi and any VPNs off and switching the connection to the Smart SIM. Once all three stages pass with a green tick, you're good to go.
If you need any help with the connection test, check out our Test Connection Guide.
