Airtel — unable to send sms from my phone

Address:

560085

Hi team,

My name is praveen. And i'm facing some issues with my airtel 4g postpaid number. I'm able to make calls and receive calls. I'm also able to use my data and receive sms. But, i am unable to send sms. I'm able to send it through my docomo number. I have oneplus 5 handset (I don't think it is a handset issue as i can send sms from my docomo number). I was able to send messages a few days ago, but not since 2 days. The sim is in tray 1 and has reception. My phone bill is due in 12 days, so even that's not a problem. I have attached the screenshot of my device details as well. Kindly look into this issue asap.
