Update on metroPCS APN settings.
Hello, all:
I just set up two phones on metroPCS, one of them a new Kindle Fire phone for my wife, and my Samsung S4 GT-i9500 [PhoenixROM]. I tried utilizing the settings supplied on the phone after the initial configuration; Internet connectivity from the phone did not work. I tried the settings listed here, but I continued to experience the same issue.
After dealing with these not working, I ended up taking a look at my wife's phone, which had worked without any problems immediately after setup. Upon comparing her settings to the settings listed here in XDA, the one big difference I had noticed was on the APN setting. When I changed the setting to what she had, it started working immediately.
If anyone is having a similar problem, change the "APN" setting to: fast.metropcs.com vice fast.tmobile.com (or fast.t-mobile.com); it should take care of the problem. HTH someone like the site has helped me.
