I got my ZTE a few months ago, and it's worked fine...until my aunt asked me to download Messenger from Google Play. It wouldn't download. I kept getting an Error 498, I believe. Google Play techs tried for over an hour to help, and finally said it must be a problem with the phone's settings. They transferred me to two different people at ZTE, one who hung up on me and the other who had such a thick accent and was so insufferably rude, I wouldn't talk to him again if you paid me.
I went to my local AT&T store, and they figured something was wrong with the 4G settings...that I'm not getting proper 4G coverage even though it's enabled. Perhaps this is the reason my brother sent me something that said "Download MMS (1KB)" but it refuses to download?
Also I tried to send him a cute little Messenger sticker, and it never uploaded.
I'd like to get that resolved, and I'd also like to find out how to reset my data usage settings. The graph just keeps filling up more and more, and nothing in your online manual showed how to reset it to 0.
Many thanks for your help!
