Two questions that were on my simple mind. :eek:

1. Anyone knows that If I turn off Data/Voice Roaming (Cellular Section), can I still get, and use data/phone call functions with 3G or LTE nationally (USA) ? Not planning on going internationally. These two area's were "On" by default.


2. Also, unknown if anyone has done this, just tried it myself by turning things on and off with my new iPhone. Doing a speed test with CDMA turned on, I got around 22 MB download speed on LTE in my neck of the woods (Dunedin, Florida) but when I turned off International CDMA under Settings > Cellular > Roaming, I now get 31 MB download speed with LTE. Big increase between the two. Has anyone else notice this and does anyone know why ?

Could just be a coincidence. I've run multiple speed tests back to back with no change in settings and got different results.

I don't really notice any differences in quality of connection from turning International CDMA on or off, either.

I'd say just leave it set to whatever way works best for you in your area.

Seems like your using two different servers for the speed test which I have in the past noticed can yield very different results.

Your right. Didn't even notice that until now. Thanks for the observation
