S21 fe sd888 mobile data is not working

[Sanju214]

So my s21 fe SD888 mobile data was working on Sunday 28. But now it's not working. 5g 4g both is not working. Calling and sms are working just fine. I have checked the sim in my old phone. 5g and 4g both are working in old phone with same sim.

Before writing this here I have ensure:

SIM card is active

Mobile data is turned on

Data plan is active

No mobile quota for daily / monthly

Wifi is off

Good signal strength

Checked Data roaming is enabled disable 

Software is up to date 23 April 2024

Rebooted the device

Reset network, Wifi and Bluetooth settings.

Anyone getting similar issues? I'm using Airtel SIM but sim is working fine in my old android phone. Network is fine old phone

Please help me to resolve it

I'm getting this error while using *#0011#. Also can you tell me how to get log file?

[Sanju214]

Done.

Also I got the answer that might be correct. I inserted jio sim in my phone and both 5g 4g worked. But in airtel sim, data is not working in my phone only. Also in my phone APN is not added for my sim. That might be the reason behind it. My phones APN for airtel is empty, thats why I can call and message but cant access the internet.

I did this but phone stuck on reseting the APN. Last time I did it took 5 min. BUT still doesn't add anything in APN. I tried to add APN manually too, Just copying everything from old phone, But after pressing add button, It still doesn't work. It's still empty.
