I've had my GS3 activated as a "Bring Your Own Phone" on Net10 since the beginning of December and in that time I've spent 197 minutes (per call logs) to tech phone support. I have no idea how many hours I've spent online trying to find answers to my setup problems. Most of the time I call because my mobile data just stops for no reason. Most of these calls end up with me changing all or part of my APN settings. Most of the time these changes do work but sometimes only near home, or only for a few days. I don't understand how the APN settings function or why it would ever be necessary to change them once the phone is working. For the past 10 days or so I've been using an "att.mnvo" APN set. Friday I activated a GS3 for my wife and was given the "tfdata" settings and they worked perfectly. For grins I tried it on my phone and nothing worked. Yesterday my mobile data quit around noon so in the evening I made another call to Net10 and was given the "tfdata" settings. I reluctantly entered them and they worked. Why? The tech "explained" my previous settings were temporary (all of em??) and THIS time it's permanent. BS. My phone is a GT-i9300 and can not get LTE--but the wifes is a SGH-i747 and does get LTE so I can understand that our settings may be different. I just can't understand why mine keep changing. Am I alone in having these provisioning problems? Can anyone tell my WHY I have to keep making changes? Are they monkeying with things at their end that only affect me? My only glimmer of hope in dealing with this provider is my wifes phone works great and hasn't had any problems at all since activated 4 days ago.
