Read it again you need only one sim card for all accounts.are there existing services who sell unique phone number verificaiton ? i dont want to go to a shop all the time ;D
Buy a real sim card verify your account than remove your no. from the account and verify a new account using the same no. repeat it for all accounts.you can also re-verify your accounts using a single sim card.
I have try this for three accounts and all accounts working fine for now.hope this work for you also.
All other virtual phone or disposable no. are waste of time.
Thanks.
I never face temp ban if that happen can't we re-verify account using same sim card as its not linked with any account and was used to verify the same account?When you remove your phone number from your account, what can you do if facebook gets you temp ban ? You won't have the phone verification option and will lose your account!
