Because a lot of foldable phones haven’t had global releases you might be tempted to import them. For example, the Oppo Find N2 and Xiaomi Mi Mix Fold 2 have incredible looking hardware but are China-only releases for now. If you import a phone like that, be aware that it will likely have Chinese-oriented software and won’t come with the Google Play Store installed. You’ll be able to get Google apps on there, but it will be a bit of a faff. Importing a foldable also means you will lose out on in-country support for warranty claims or repairs. If you are desperate for a folding phone but it’s not out in your country, it’d be better to import a phone with Google services. If you’re in the US, it’s not an awful idea to import, say, the Oppo Find N2 Flip from the UK, as it will have Western software and likely work on 4G and 5G bands in the States. Always check the specs first though, and buy from a reputable source.
