I just switched from my broken iPhone 5s to a ZTE Prestige 2 not too long ago. I am experiencing lag in multiplayer games and uploading 10-15 min videos on websites takes hours. This wasn't happening when I was using my iPhone 5s with Boost Mobile. I used the speedtest app and saw that i'm getting ping spikes in the 500s and my upload speed was barely even 1 mbps (photo attached). I've already tried resetting my network and APN settings. Is this a problem with the ZTE phone itself? I would appreciate anyone's help.
