I took contact with the suppot of blockchain.info and said the cause is my provider who blocks the sms but i took contact with my provider and he said this is not the case otherwise i would never receive an sms from blockchain.info
are there other persons who have the same sms problem with blockchain.info?
Are you sure it's blockchain.info you are discussing about? I have not seen them using any two factor verification on sMs rather they use the app bases one like google authenticator. Or perhaps the sms may be not available in my country. The only web wallet which provides sms verification every time you log in is Circle as far as I know.
You can choose to use a free app or your mobile phone number to secure your wallet.
