How can I start Jio 4G sim in 3G mobiles?
I want to know how to start a Jio 4G sim card in a 3G mobile phone.
Sure, I can help you with that. Firstly, make sure your 3G mobile phone supports 4G LTE bands. You can check this information online or with your phone manufacturer. Once verified, you need to download and install the Jio4GVoice app from the Google Play store. This app allows you to make voice calls and send text messages through the Jio 4G network on your 3G handset.
