FNB Connect Sim

Never in My life have I heard that a deceased person state in his will what must happen to his or her sim card after passing. I just want the number kept and keep paying can allocate it to my name but no they need clarity in the will. No person state that ever. So any otp or messages from payouts still to come will I not be able to get because they can not help me at all. Thank you again FNB for nothing our own bank for how many years.
