If you ' re older than 16 , I ' m terrified . You ' re really fucking stupid . Anyone told you that before ? <| sep |> effectivement , je n ' avais pas vu , navr <| sep |> Have a question regarding this . The UPI VPA is linked to the primary mobile number from what I understand after using the app . It pulls in information of the bank accounts which are linked to said mobile number . Suppose my phone gets stolensim lost , and I deactivate the number and get a new one , do I need to get all my bank accounts updated with the new number ? Will I have to register for UPI again ? What about if there was money in the wallet linked to the old stolen sim ? On the topic of theft , can anyone enlighten me if its possible to retain mobile number even if phone gets lostsim stolen ? Is there even a need to deactivate it ? I use Airtel .
