Z_Aid The most important thing for me, as a repeat tourist to Japan, is that FeliCa would be supported for all Nothing Phone(3) users, regardless of where they bought the phone.
Suica and PASMO cards are very hard to get nowadays due to the ongoing chip shortage, and having FeliCa accessible to Nothing Phone(3) users outside Japan would allow foreign tourists/expats to easily use one device to tap in and out of subway/train gates, or to buy drinks at vending machines. I had to carry around an iPhone SE 3rd Generation with a Pixel 7 Pro during my last trip to Japan, with the iPhone SE 3rd Generation being used exclusively for FeliCa-related tasks (going through subway/train gates, buying drinks at vending machines, etc), and the Pixel 7 Pro being used for everything else.
Aside from Japan-specific features, I’d also like to see eSIM support alongside nano-SIM support, as Apple has completely removed the SIM card slot from new iPhones sold in my country.
