I have an unlocked iPhone 6 A1549, the T-Mobile one, that I currently use in the US on AT&T. I am going to Hong Kong this summer and wanted to see what my SIM card options are. I understand that China and Hong Kong use 40 and 41 LTE bands, which my phone doesn't support, and would need a A1586 for. But would my phone work with any major networks that offer prepaid data SIMs in Hong Kong? Even if it's just 3G, I'm OK with it. I see according this this list of LTE networks by country, that there are carriers in Hong Kong that offer LTE on 3, 7 and 8 bands. But having never been there before, I don't know how reliable this is. Thanks to anybody that can help.
