Ok I have a small problem.
I went and run the network set up tool but then after that my internet became dam slow even though it shows connected to 3g.
I wanna open google also take damn long.
I'm on digi.how to like undo any changes i made

Dude same thing happened to me. I was on the phone with digi for almost an hour today and they still couldn't rectify it.
In the end I did a hard reset on my phone and suddenly it was fine. I didn't even have to add the apn.
I suspect it is the network setting wizard thingy because after I ran the wizard that was when it slowed down.
Now its back to normal d.
Also btw , inside the diagnostics tool under settings when U press the three dots , there is a toggle to turn on hsdpa. I can't seem to turn that on. Any of you all can?
