I have a problem with a Samsung galaxy S4 L720 that was recently rooted. Unfortunately, I don't have the option to choose between 2g/3g or 4g for internet connectivity. I had to download APN manager and titanium for me to use internet. However, when I load credit, no matter the amount it all goes within seconds.
I have a Samsung S3 mini but don't experience the above problem because it uses EDGE.
Can someone help me on how I can have this option on the galaxy S4 L720? I mean EDGE so I can choose either 2g or 4g connectivity.
Please before I go crazy
I love my S4
