To activate your new SMARTY SIM, go to smarty.co.uk/activate. Click Yes, let’s get started. Enter your SIM number, it starts with 8944. Choose a plan and enter your details.
🚀 How to Activate Your SMARTY SIM
A. 🔹 If It’s a Brand-New SIM (e.g. ordered or bought as a bonus)
-
Go to smarty.co.uk/activate.
-
Click “Yes, let’s get started”.
-
Enter the last 12 digits of your SIM card number (usually after 8944…).
-
Choose a monthly plan, complete payment, and create your SMARTY account.
-
Activation typically completes within a few minutes, though it can take up to 2 hours. You’ll receive a text and email confirming activation.
B. 🔹 Transferring (Porting) Your Existing Number (Bring your number to SMARTY)
-
Follow steps A—but during account setup choose “keep my existing number“.
-
Enter your current mobile number and PAC/STAC code from your provider.
-
Confirm the switch and select a port‑in date (must precede PAC/STAC expiry).
-
Complete payment and finish your order.
-
On the chosen date your number will transfer—SMARTY usually completes the port within 1 business day and you’ll get confirmation when it’s done.

C. 🔹 Via the SMARTY Mobile App
-
Download the app for iOS or Android.
-
Tap Join SMARTY → Activate SIM, then scan or manually enter the SIM barcode or number.
-
Follow prompts to pick a plan, enter your details, and pay.
-
Optionally choose to port your number during setup.
✅ Activation Tips & Troubleshooting
-
Timing matters: Activate your SIM on the day you want your monthly billing to renew, as that date can’t easily be changed without pausing your plan.
-
Allow up to 2 hours for activation to complete.
-
Restart your device or reinsert the SIM if it doesn’t connect immediately.
-
Ensure your device is unlocked and supports 4G VoLTE (or 5G)—SMARTY no longer supports older 3G-only devices.
-
Insert the correct SIM—sometimes a bonus SIM is included in the packaging; only the one marked SMARTY and glued to the pack is valid.
🛠️ Support & Help
-
You can contact SMARTY’s Customer Care chat (via their website or app) available Monday–Sunday, 8am–8pm UK time. There is no phone support.
-
If activation hasn’t completed within two hours, they can check and assist directly via chat.
