Hi yungree, congrats on the new phone!
My Moto G (US GSM) isn't my daily driver, I mainly use it as a media player (an iPod Touch if you will) at work and home. I did run it through some paces on T-Mo for a month to bother try their service and use the phone, as, well a phone.
Some pros:
-PRICE!
-Size, how it feels in the hand. My wife has a Moto X and this one feels just as good. It's a little small feeling next to my G2, but I dig it when just pecking through Google Music.
-Battery life. Well, it's good, but my use case is very different so YMMV.
-Screen. It's solid, and reminds me a bit of my old Gnex despite not being AMOLED.
-Latest software. My model is still behind some others (like the Verizon variant
) but still being on 4.4.2 is just fine for me. The bundled Moto software is limited but useful. Also, depending on where you go yours, no bloat!
Cons
-Honestly, the only thing is the camera. It's just... bad. If you have good lighting outside, it can be fine, but otherwise, don't bother.
Overall, I love this phone. If I had to use T-Mo or travel overseas, I'd be more than happy with it. HSPA+ on T-Mo was plenty fast for me since LTE is so congested in DC.
Anyway, enjoy your new phone!
