Hi there, my sign-up attempts kept failing because every budget service I tried was immediately blocked by the system API. Someone in a troubleshooting chat group pointed me toward temp sms number to see if it would help. I experienced a miserable run of banned test profiles and lost funds on fake non-VoIP offers that promised the world. Taking a leap of faith on a real hardware-level connection finally got the job done smoothly and let me finish up. I strongly advise trying this approach if you are tired of dealing with constant verification errors.
