Nope 4g is still non functional much times
get a t-mobile sim card. plug it in, get the free 200MB data plan, test it
your slot might just be dirty, or the tablet just doesn't receive good LTE signal
Are new phones coming in August? The moto x I had is not non functional and it's insured. Do you think it's worth waiting till august until my birthday if new phones are coming out? I don't pay full retail if my old moto x is insured right?
