Hi there@MHK, and welcome to the Community.
It sounds like the issue you're experiencing is specific to WhatsApp, and not with your Bell Mobility services. Have you attempted to verify your phone number with WhatsApp with theirCall Meoption? It's specifically offered for WhatsApp users who are unable to complete verification via text message. You can read more on WhatsApp's support page for verification
If you're having issues receiving text authentication in general, try sending a text message to the short code 28849 with either the word INFOor HELP.This shouldreset the 2FA routing to your device. The routing resetmay take a few hours to complete. If an answer is received from INFO or HELP, then no action is needed and your text authentication is set properly and you will need to contact the sender for further verifications.
Try that out, and keep us posted.
