The mobile number prefix 0951 or +63951 in the Philippines is primarily associated with Smart Communications and its subsidiary, Talk ‘N Text (TNT). However, with the implementation of the Mobile Number Portability (MNP) law, subscribers can now switch networks without changing their mobile numbers. This means that a number starting with the 0951 prefix, originally assigned to Smart or TNT, could now belong to a different network if the user has ported their number.
