There are dire warnings on the forum about VOIP services being blocked for 2FA (OTP's) after 24 hours use. However, I'm from U.K. and have used 'VYKE' since March with 100% success for High Street Banks, Neo Banks, Cloud Services, Government Departments and Email providers etc. Maybe this could change but for £12 per annum to rent a U.K. virtual mobile telephone number I'm taking my chances and continuing.
