Whatsapp Otp Delivery Problem

I use WhatsApp with the phone number +91 72570 066** on my iPhone 13. For the last 2 days I have not been receiving the OTP required to verify my number and log in. The verification screen keeps asking for the 6‑digit code, but no SMS OTP ever arrives on my phone. I have already tried basic troubleshooting such as reinstalling WhatsApp and restarting the phone, but the problem continues and I still do not receive any OTP for this number. I request that my phone number be checked and that the OTP delivery issue to +91 72570 066** be urgently fixed so that I can verify my number and use WhatsApp again.
