Does an iphone bbm pin change with new id

A blast from the past!

BBM (BlackBerry Messenger) was a popular messaging service on BlackBerry devices, but it's no longer available on iOS devices like the iPhone.

However, I'll answer your question based on the assumption that you're referring to the old BBM service.

When you change your BlackBerry ID (BBID) on a BlackBerry device, your BBM PIN (Personal Identification Number) does not change. Your BBM PIN is tied to your BBID, so even if you change your BBID, your BBM PIN remains the same.

However, if you reset your BBM PIN, it will change, and you'll need to update your contacts with the new PIN.

It's worth noting that BBM is no longer available on iOS devices, and BlackBerry has since discontinued the service. If you're looking for a similar messaging experience on your iPhone, you may want to consider alternative apps like WhatsApp, Facebook Messenger, or Signal.
