In the past, standardizing SIM information as the rightful owner was entirely voluntary, without coercion, when issues like spam sims and harassing scam calls were less prevalent. However, since March 31st, the government has been stricter on this matter, swiftly shutting down sims if the switch to authentic SIMs isn't made. If you've purchased a SIM from private sources with unclear origins, check your phone number and promptly switch to an authentic SIM.
