I've searched a number of threads here and can't find a consistent or concise answer for my issue. I have an unlocked T-Mobile LG G2 (801) that I want to use on AT&T. I put my AT&T sim card in the phone and can get calls and texts, but no data. So, what I would like to know is,
a) can I use my AT&T sim card in this phone and get data (this seems totally possible, based on what I've read, but I haven't found the right settings apparently)
b) if I can get data using my AT&T sim card, will it be 4G / LTE, or HSPA?
c) will rooting this phone better my chances of getting this to work, and/or getting faster data?
Thanks in advance for your help!
