Alternate guide to add apn for data on sim unlocked gs4
This is a short and simple guide to change apn settings on sprint/verizon androids and all others that are locked by default.
• First off, your phone has to have root permission.
• Download "apn manager PRO" and install on your phone.
• Download "titanium backup PRO" and install on your phone aswell.
• Next, open the app titanium backup pro and look for apn manager pro under the backup/restore tab. Once you see the apn manager pro app, long press it until a menu shows up. After you see this menu you want to select the last setting that says convert to system app.
Thats it you are finished. Now you can open apn manager pro and add the new apn of your choice.
This is a known method, personally the easier one imo. If it helps just hit thanks and confirm. Enjoy your new data settings and keep hacking :beer:
