Not getting whatsapp verification code after reset

[ankmonk]

Recently I reset my S21 FE and installed WhatsApp after that. Tried setting up, but not getting verification code neither via SMS nor via Phone Call (Jio). Please help. I've been trying since last 3 days without any success. 

For another SIM (Airtel), I set up WhatsApp Business without any problem.
