(5 Reviews)- February 26, 20195 out of 5The data plan on my phone was blocked. The techician in charge at the store spend a good amount of time helping me to unblock the phone. I tried another store previously, but the employee was not so helpful. Also, I asked him about a buffering issue that frequently occurred when I watch live streaming on DirecTV Now. He said he will bring this issue up with the DirecTV Now rep next when he see them
