How to Avoid TNT SIM Registration Portal Errors
Trying to register your TNT SIM only to hit errors on the portal can be really frustrating. Whether the site won’t load, your ID photo won’t upload, or you’re not getting the OTP, most issues can be fixed quickly with the right steps. Here’s how to avoid errors and finish your SIM registration smoothly.

Use a Stable Internet Connection
One of the easiest ways to reduce registration errors is to start with a strong internet connection.
• If your Wi‑Fi is weak, switch to mobile data.
• If your mobile data is weak, connect to a reliable Wi‑Fi.
A slow or unstable connection can cause timeout errors, failed uploads, or incomplete form submissions.
Make Sure Your Browser Is Ready
The registration portal works best on a modern browser like Chrome, Firefox, or Safari.
• If the portal won’t load, try a different browser.
• If upload buttons aren’t working, clear your cache and cookies and reload the page.
Old cache or data can cause glitches with forms and uploads.
Take Clear Photos of Your ID
Many registration errors come from blurry or unreadable ID photos.
To avoid this:
• Use good lighting with no shadows or glare
• Make sure the entire ID card is visible
• Use JPG or PNG photos with reasonable size (5MB or less)
• Avoid cropping out parts of the ID
If the system can’t read your ID photo, it may block your registration.
Give Camera Permission for Selfie Verification
If you need to take a selfie on the registration portal and it says camera error, check your device settings.
• On your phone or browser, allow camera access for the site.
• Try a different device if the camera isn’t working.

Enter All Details Carefully

Wait for and Enter OTP Correctly
After you enter your mobile number, the system sends a one‑time password (OTP) to verify your number.
• Make sure you have good network signal so you can receive SMS.
• Enter the OTP carefully — if you enter it too slowly or make mistakes, it may expire.
• If you don’t get it, try toggling airplane mode or restarting your phone before requesting again.
Try the Mobile App (GigaLife or Smart App)
If the web portal keeps giving errors, try registering through the official mobile app instead. Many users find the app easier to use and less glitchy than a browser.
Restart and Try Again
Visit a TNT/Smart Store if Needed
If you’ve tried everything and you still get portal errors, go to an official TNT or Smart store. Store staff can help you register your SIM in person and avoid all the online errors.
