Answered question
I lost my old phone, I am supposed to receive and answer a text message on my old phone in order to transfer my number with bell to my new phone, is their any way to still keep my old number if I can't answer the text message?
I assume your Bell Account is still active? I suggest you reach out to them directly, confirm your identity and ask for some other ways to transfer.
Another option would be to go to Bell directly and get a new SIM.Usually they can cancel the old one and you can receive texts to the new SIM card. They simply link your number to the new SIM.
I personally never had to answer a text when I transferred numbers.
