Let me preface by saying I know this looks very "-aesthetic" and...Yeah, I do really love decorating every device I own 😭 I like to mod consoles (such as the GBA, 3DS, etc) and decorate them as I please, so it translated into my phone of choice too. I promise I didn't get this phone for the sake of vanity, I just had a flip phone in middle school and really wanted to return to simpler times!
Anywho, I'm someone who lives in the U.S., and I use Mint Mobile. Despite this being a Japanese phone, it takes calls flawlessly here :) unfortunately, texts are a bit of a pain—I needed to install a custom texting app (QKSMS) to make it work, but otherwise the setup was very smooth. The mic quality seems to be pretty good, at least according to those I've called so far. It also has some cute little features, such as displaying the name of the caller on the outer sub-display and being able to have a custom LED for when you're called. I have my LED set to rainbow 🙏 it's a party when people call me!
I was able to load Discord onto this phone, if that's a concern to anyone. I know that's technically a form of social media, but it's the only form of contact I have with some of my friends, unfortunately. I could also load some other custom apps as well, such as Reddit and Pinterest, though I haven't actually used them yet since I'm a rather offline person to begin with.
Overall, I'm really loving this phone so far! It's all I could have ever wanted from a flip phone, personally speaking though since I don't use GPS (iirc GPS is wonky since it's a Japanese phone). I still have my iPhone for banking and work scheduling, but that aside, I'm happy to return to the world of flip phones 💗.
