How to Fix TM SIM Card Registration Failed Issues in 2025

If you’re having trouble registering your TM SIM card, don’t worry—many users face similar issues. Below, we’ve outlined simple solutions to help you fix common problems and complete the registration process smoothly.

1. Issues with Large ID Files or Blurry Selfies

One of the most frequent problems during SIM registration is uploading large files or blurry photos. If your ID file is too big (over 2 MB) or your selfie isn’t clear, the system may reject your submission.

How to Fix It:

  • Resize your ID file to ensure it’s smaller than 2 MB . You can use free online tools to reduce the file size without losing important details.
  • Make sure your selfie is clear, well-lit, and fully visible. It should also be less than 2 MB in size.
  • Save your ID in an accepted format like PNG, JPG, HEIC, or PDF . If it’s not in the correct format, use an online converter to change it.
  • Double-check that both your ID and selfie are sharp and easy to read before uploading.

2. Incorrect Information During Registration

Entering wrong details is another common reason for registration failure. Even a small typo in your mobile number, OTP code, name, or ID number can cause the process to fail.

How to Fix It:

  • Carefully review all the information you enter during registration.
  • Double-check your spelling and ensure the details match your valid ID.
  • If you’re unsure about any field, take a moment to confirm the correct information before submitting.

3. Registering After the Deadline

If you miss the SIM registration deadline, your TM SIM card will be permanently deactivated. Unfortunately, once deactivated, the SIM cannot be reactivated or reused.

What to Do:

  • Act quickly to avoid missing deadlines. Keep track of official announcements from TM regarding registration timelines.
  • If you’re unsure about the deadline, contact TM customer support or visit their website for updates.

4. Faulty or Damaged SIM Cards

A damaged or faulty SIM card can lead to signal issues or prevent proper registration. If your SIM card is scratched, dirty, or not working as expected, here’s what you can do:

Steps to Fix It:

  • Visit the nearest TM Service Center for assistance.
  • Request a replacement SIM card while keeping your existing mobile number.
  • Ensure your new SIM is properly activated after replacement.

5. Weak Signal or Internet Connection Problems

Poor internet connectivity or weak signals can interrupt the registration process. This often happens in areas with unstable network coverage.

How to Fix It:

  • Move to a location with better signal strength, such as near a window or in an open area.
  • Check your TM APN settings to ensure they’re configured correctly. Incorrect settings can lead to slow or unstable internet. Adjust them if needed for improved performance.
  • Wait until the network service stabilizes, then try registering again.

Frequently Asked Questions

There are several reasons why TM SIM card registration might fail. Understanding these common issues can help you avoid or resolve them quickly. Some of the most frequent causes include:

  • Uploading Large ID Files: Submitting files that exceed the size limit (usually 2 MB) can lead to rejection.
  • Missing the Registration Deadline: Failing to register your SIM before the official cutoff date will result in deactivation.
  • Using a Scratched or Dirty SIM Card: Physical damage or dirt on the SIM card can interfere with its functionality.
  • Faulty or Disconnected SIM Cards: A damaged or improperly inserted SIM card may not connect to the network, causing registration to fail.

These issues are common but can often be resolved with simple troubleshooting steps.

If you fail to register your prepaid SIM card before the deadline, it will be permanently deactivated . Once deactivated:

  • You won’t be able to send or receive text messages.
  • Calling services will no longer work.
  • Mobile data access will be completely disabled.
  • All other mobile services tied to the SIM card will be unusable.

To avoid losing access to your SIM card and services, make sure to complete the registration process before the deadline. If your SIM is already deactivated, you may need to visit a TM service center to reactivate or replace it.

To verify whether your TM SIM card has been successfully registered, follow these simple steps:

  • Open your phone’s messaging app and send the keyword “SIMREG” to 8080 .
  • You’ll receive a confirmation message shortly, informing you of your SIM card’s registration status.

No, you cannot use a new SIM card without completing the registration process. Under the SIM Registration Act (Republic Act No. 11934) , it is mandatory to register your SIM card before using it for calls, texts, or mobile data.

Failure to register means your SIM will remain inactive, and you won’t be able to access any services until registration is completed. Make sure to register promptly to avoid interruptions in service.
