I had several reservations ordering this phone after reading so many of the poor reviews. Although Amazon LLC sells the item, it's over one-third more than other sellers. Before buying, I contacted Amazon customer service and they said I would get a full, no questions asked refund if the phone did not work with my SIM card if I used either Amazon or an Amazon Fulfillment seller. So I went for such a seller, less than Amazon LLC but not the rock-bottom cheapest.
