The mobile number prefix 0952 or +63952 in the Philippines is primarily associated with Smart Communications and its subsidiary, Sun Cellular.
However, with the implementation of the Mobile Number Portability (MNP) law, subscribers can switch networks while retaining their original numbers. This means a number starting with the 0952 prefix, originally assigned to Smart or Sun Cellular, could now belong to a different network if the user has ported their number.
