Bests & Worsts Reviews from Amazon

I checked with tech support of my current wireless provider (Net10) prior to purchasing this phone, to confirm whether or not it was compatible with their service. Unfortunately they mistakenly told me it was. So I bought it. Come to find out this phone does NOT work through their AT&T SIM/towers. They advised that it should work with T-Mobile compatible SIM/towers. So I took the phone over to MetroPCS (a T-Mobile partner), then to T-Mobile itself, and confirmed in both cases that the phone does NOT work with them either. Now I've spent untold hours on numerous support calls and chats, doing extensive research, visiting phone shops, and still don't have a working phone. Not only that but I spent extra money buying a SIM adapter. Anyone considering buying this phone ought to do extreme due diligence about ascertaining a wireless provider beforehand. I would love if someone could say here what service (as of Sep 2018) this phone actually DOES work with, in the US. I could update this review if I could actually get the product to work, but for now, to me, the phone is worthless and I've only wasted countless hours on it. Very unsatisfied. The phone also does not come with any instructions, but for a 3-page foldout with a pictograph on how to insert the SIM card. Other than that one has to figure out everything about how this phone operates on one's own. If you are not a techie or get easily frustrated with phones/technology, be warned.
