Network issues after battery replacement.

[_Junaid]

Hello, I'm using my galaxy note 20 since 3.5 years and everything was working fine except I'm facing battery drainage issue as the battery got weak after heavy usage. Recently I changed my battery from an authorized Samsung service center and after that I'm facing network issues. 

My phone shows emergency calls only where in my office where I used to get good to fair network. Did someone faced the same issue and what's the solution? 

Thank you.

Hello I am using samsung flip5 since 1 week I have updated to esim where all the banks where registered to that number now the app cannot recognize the Sim what is the solution

Go to the Jio/airtel/VI gallery and buy a physical SIM, Within 2 hours, your ESIM will go off, then delete the ESIM and put in the physical SIM. It'll work most probably. If it doesn't, then your network provider or Samsung Care will help. If it's important for you to use esim only, ask Samsung support for help or visit a service center.
