The next version might on the Fairphone 5, not sure what if any other phones. I forgot in the US, you needed that. You may or may not be able to even connect without it.
Sounds like if 2G is available, not sure when they said that worked, you can change it to that, and get calls.
But there’s another option, get a hotspot, and use VoIP on a Linux device, doesn’t have to be a phone.
postmarketOS has experimental VoLTE. But Ubuntu Touch & postmarketOS aren’t collaborating on bringing it to devices, not sure why. There should be a more unified development of Linux on phones, but apparently there isn’t. Somebody from postmarketOS tried contacting somebody from Ubuntu Touch, but didn’t get a response. Didn’t read all the posts, so don’t know if they ever did.
Oh and another option is to wait, and see if the iPhone 15 gets some kind of exploit, to jailbreak it. Might be too late for me, if they find a software exploit, on the latest iOS 18, I won’t update to 26 or whatever, don’t care. If it’s a hardware exploit, they can support more iOS versions easier.
I might just wait and see what happens, might not even live long enough to need a new phone of any kind. Not sure how long I’ll last with the BS the ones that control the government are doing. Might have a heart attack. Or a stroke.
And finding a good seller of old phones in the US won’t be easy. I might have found one seller that might be worth the risk, it comes degoogled, so the bootloader can be and is already unlocked. But then I remembered it’s used, and doesn’t look like it has a new battery. Probably not worth the price. Doesn’t even have 5G. Not that it’ll matter when World War 3 is happening.
The phone I wanted, the seller is also selling a used pin locked phone, sounds like a stolen phone. And some concerning back feedback. Not giving them any money. Too risky. Not to mention, they could be stolen phones, even if new, somebody in another country, could have stolen them, and sent them here to be sold. Something fishy might be going on. Most of the phones on eBay are either stolen, or not what they say it is.
If you buy one on Backmarket, you may not get an unlocked one, and the next one might not be either. Apparently they have no way of knowing what is being sent to you in advance. Even a review said they got multiple, maybe 4, all Verizon phones. Were they locked though? Well, some or maybe all Verizon phones, can’t have the bootloader unlocked, so good luck flashing Linux on it.
Some T-Mobile phones, might require you be the original buyer to unlock. You need to unlock it to unload the bootloader. If it’s made by OnePlus, you also get to flash it to the global ROM, and only Windows is supported for flashing it, can’t use a VM. So even if it’s T-Mobile and unlocked, not worth the trouble.
I won’t import a phone, not paying tariffs, which is basically giving money to assholes, so they can do more BS.
The seller might have a Xiaomi Mi A1, which works with postmarketOS. Nope, some really old Sony crap. Got them mixed up. Nope, no good sellers of that on eBay. Good luck finding any phones from Xiaomi in the US from a good seller, that work with Linux. Sounds like depending on the one, you might have to jump through hoops to unlock bootloader as well, not that one I don’t think.
LOL the seller of a OnePlus Nord N10 5G gave me an offer, maybe $5 less then list price. It’s T-Mobile unlocked, too lazy to reboot desktop with an external drive, and Windows 10 on the drive. Under $100, but no idea if it’ll get VoLTE either. Maybe it has experimental support with postmarketOS. Not sure I trust that seller anyways.
Samsung Galaxy Tab 2 7.0 might work with postmarketOS, I had or have some old Samhung tablet. No idea which one. Probably too slow. Only 1 GB of RAM, might work as a bare minimal softphone for VoIP. Don’t do anything else on it though.
