Should a user fail to register his SIM within the deadline, it shall be automatically deactivated, subjecting him to a lot of hassles.
The Department of Information and Communications Technology (DICT) said as users have until until April 26, 2023 to register their SIMs. The DICT, however, can extend the registration for a maximum of 120 days more or until August 24.
But once the SIM is deactivated, the user can no longer have outgoing and incoming calls.
He can’t make or take urgent and important calls to and from everyone nor can he communicate with colleagues at school, work, or business.
The user will no longer be able to send and receive messages as well.

On top of being unreachable to others through text, he will not be able to get his One-Time Password (OTP), which is now a common security feature in many social media apps, digital banking services, and online shopping sites linked to his account.
In addition, the user will lose his internet access.
The Internet has become essential in our increasingly digital world. More than not being able to enjoy favorite apps and sites, having no internet access also means getting cut off from important information and services that make life simpler and easier.
Furthermore, the user will lose all his load balances. Once the SIM is deactivated, all his remaining load balances will be forfeited.
Users who missed the deadline and got their SIMs deactivated may still process the reactivation of their SIMs not later than five days after the period set by the law.
But they can avoid all these hassles by registering their SIMs now.
