If you’re looking to upgrade your Android phone to 4G, there are a few things you can do. First, make sure that your phone is up to date with the latest firmware. This can be done by going to Settings and selecting “About Phone.” Then, check the box that says “Update my phone now.” If your phone is not up to date, you can update it by going to the Google Play Store and searching for “H+ 4G.” Once you have updated your phone, make sure that you sign in with your Google account and update all of your apps. Finally, if you’re using a H+ account on another device (like a laptop or computer), make sure that the H+ app is updated as well.
