WhatsApp Verification SMS Not Received on New Number

I have been unable to register my new Turk Telekom line with WhatsApp on my Android phone since 14.09.2026. My device is a Samsung A23 and there is no problem with either the device or my internet connection. My new number is +90 554 2** 32 0*. When I try to register this number with WhatsApp, I constantly receive the warning “WhatsApp is temporarily unavailable; please try again in 1 hour” and no SMS verification code is ever sent to my line. At first I was informed that my number would be reviewed and I waited two days, but afterwards I kept getting the same “try again in 1 hour” warning and the verification SMS still did not arrive. When I contacted Turk Telekom, I was clearly told that there is no spam, banned status, block or any other restriction on my line that would prevent SMS messages from being delivered. I have emailed WhatsApp support many times and also submitted complaints through the in‑app support section, but I only receive automatic replies and have not been able to reach a real representative. Since I handle all my communication through WhatsApp, I currently cannot do my job and this situation is causing serious grievance and loss of income. As the legal and current owner of this new line, I request that any possible spam or block record originating from a previous user on this number be removed, that the verification SMS be sent to my number, and that I be allowed to use WhatsApp without any problems.
