Internet connection - Consumers need to have their internet connection switched on to receive the WhatsApp message. People can Send Bulk SMS without an internet connection necessity; the message would directly reach the target audience via their phone number.

Device accessibility - Standard Bulk SMS is compatible with different types of phones, unlike a WhatsApp Bulk SMS, which is accessible only for users who have the app installed.

For the best reach potential, utilizing both mediums can be better for businesses rather than having a single one.
