hello @avijit3 , no, you will need a valid phone number.
sim card lost or not, without valid mobile number, you need to contact paypal customer service.
Due to the fact that you do not have access to your old phone number, you will need to contact our telephone support team.
Please go to the PayPal home page and
1. Go to the Contact Us page: https://www.paypal.com - contact us
2. Select Password and account access
3. Select Connection issues
or
during working days and hours of operation
by messaging from paypal, by phone, and also on Facebook and Twitter (PayPal customer service is present above)

then at the bottom of the page that opens "contact us" (on the right) and finally, still at the bottom right: "call us"
