Upgrading BSNL SIM card to 4G?

The issue with a new BSNL 4G SIM

The problem with the switch is that the SMS service will be barred in the new SIM for the first 24 hours.

If you have your credit card/ bank account or Aadhar card attached with the phone number, you will not be able to make any transactions or verify your phone number in the next 24 hours. Because the OTP SMS won’t be coming.

Moreover, all the UPI apps are sensitive to a SIM change and will reset on your upgrade to the 4G SIM. As the SMS service is barred, you will not be able to re-verify for the UPI services either. So you will not be able to make UPI transactions either.

This actually is a security feature that protects you from fraud using BSNL SIM. As I can understand, this restriction is also present if you change your BSNL SIM. Either because of damage or SIM not working issue.

If someone fraudulently swaps your SIM, SMS service will not be available for the fraudster too. As you will not be having network in your SIM, you will have 24 hours to take action. Thus preventing something untoward.

How should you proceed

Plan your SIM change beforehand. Make all the necessary transactions before switching the SIM. Then only change the BSNL SIM to 4G.
