You've bought your Classic SIM and you're ready to get up and running? Here's a step-by-step guide to help you activate it quickly. Whether you're transferring your number or getting a new one.
Install your SIM 📲
If you have a physical SIM, just put this in your phone (we provide a SIM ejector tool with the SIM).
If you ordered an eSIM, you'll be sent an email with detailed instructions on how to install the SIM on your phone. You'll need to use the activation code sent in your email to navigate to your phone's settings and download the eSIM. It's basically a case of scanning the QR code provided or using our manual codes.
🔔 Installing the SIM doesn't activate your Honest Mobile service. Follow the instructions below to get your SIM activated.
Get started in the Honest Mobile app 🟢
Before you begin, make sure you've downloaded the Honest app.
👉 Download the Honest app
Then follow the instructions below:
Open the Honest app
Sign up or log in using the same email you used to order your SIM
Tap on the SIM you want to activate
Enter the last 4 numbers on the back of your SIM (If you're using an eSIM, this info will be in your signup email)
Transfer your number or choose a new one 🔁
After entering your SIM details, you'll be asked to choose between:
Option 1: Transfer your number
Tap Transfer your number
Have your PAC code ready (you’ll get this from your old provider)
Enter the PAC code in the app when prompted
Option 2: Choose a new number
Tap Choose a new number
Follow the on-screen steps to confirm
Final steps ⚙️
Before you finish the activation flow, you’ll be able to:
Confirm or change your plan
Enable or disable roaming outside the UK and EU
Set a bill cap to avoid unexpected premium rate charges
Double-check your details
Tap Activate SIM to finish
Activations typically take 15-30 minutes (up to an hour in some cases), so grab a cuppa while we get everything sorted.
