How to create new accounts on Facebook with the same mobile number

My experience today: Today I was testing the Opera browser and I started to create Facebook accounts and I already had no free number to activate my Facebook accounts and to my surprise with "Opera" I managed to create up to four Facebook accounts , shared this with you. Thank you

I'll try, thanks for the info

I tested this method, unfortunately soon after I started working with one of the entries.
All accounts have been blocked for me
