| As mariners preparing for USCG exams, you know that staying connected while ashore or between voyages is critical for accessing study materials, receiving exam updates, and coordinating with training centers. However, many seafarers overlook a key requirement: proper SIM registration under national laws (similar to the Philippine SIM Registration Act, RA 11934). Unregistered SIMs are deactivated, cutting off access to OTPs, study apps, and family calls. To avoid losing your mobile number during critical study periods, complete your TM SIM registration using the official portal—just like keeping your MMC (Merchant Mariner Credential) valid, keeping your SIM active ensures seamless access to USCGQ practice exams and forums while on land. Stay prepared both on the water and on your device. | |
