After receiving the short message from Unicom, I need to stop the 2G network and replace the 2G mobile phone with the 4G mobile phone. Should I turn on the 4G switch in the future? I'm not calling now. Eligible Unicom 2G/3G users can use their mobile phone numbers to log in to Unicom's online business hall: click business processing > upgrade 4G on the home page, select the 4G package you need, and click "change" to handle it.

Tips: From 0: 00 on the last day of each month to 8: 00 on the following month 1 day, old users of 2G/3G can't switch to 4G packages for the time being. After successfully switching to the 4G package, they need to restart the mobile terminal to use the Internet function normally.

1, using Unicom's 4G package or package has enabled 4G Internet access;

2. Put it on a mobile phone that supports Unicom's 4G network;

3. If the area covers Unicom's 4G network, it can be used.

Note: SIM card needs to be replaced with USIM card to use 4G network.
