The mobile number prefix 0974 in the Philippines is primarily associated with Sun Cellular, which is a subsidiary of Smart Communications.
However, with the implementation of the Mobile Number Portability (MNP) law, subscribers can now switch networks while retaining their original numbers. This means a number starting with the 0974 prefix, originally assigned to Sun Cellular (Smart Communications), could now belong to a different network if the user has ported their number.
