I recommend against Hawaii. It’s not exactly self sustaining since there are too many people living there. Housing/rent is crazy high so there are many homeless. Everything is much more expensive. Jobs can be hard to find. The islands are sinking. Storms still hit every season. Depending on the island, you may be dealing with volcanic eruptions and vog. And I do believe their coral reefs are bleaching. It sounds like a disaster waiting to happen. Then factor in the locals, they only want locals living there and to restore their Hawaiian Kingdom, #GoHomeHaole. Best to pick somewhere else.
“Permanently locked bootloader” means you can’t unlock the bootloader so you can flash a different OS. If you can’t unlock the bootloader, you can’t flash. A lot of phones are like this, like Samsung’s galaxy series. I got really fucked by Samsung with the S10 because of this. You need to buy a specific type of phone and security patch if you want to flash. I went with the Pixel bought unlocked from Google so I could use GrapheneOS. It was very easy to unlock the bootloader and then relock it back. I noticed you said the pixel does not have good reception in your country, I would look more into this before going with it if this is the case.
