- Suddenly being without a phone while you're travelling or dealing with something important is generally not fun
- Anything stored locally that isn't backed up is gone
- You can't transfer over your eSIM yourself
- Probably going to be a pain in the ass to get into accounts where the now brick was set up for 2FA
Anything complex enough to get over the air updates could lose its trustworthiness at any time. If a device is going to contain your digital soul, it should be simple and pluggable.
Another good reason not to buy an iPhone. As if there weren't enough good reasons already.
If you want something good and reliable, you go iPhone
Unless by "good" you mean being able to install software without Apple's blessing. Or send files to and from the device without iTunes or other similar monstrosity.
Devices need to be considered disposable. Expensive but disposable.
* All photos auto upload to Google photos
* All other important files are in a syncthing folder with at least two other devices (laptop+desktop)
* 2fa in Authy with cloud-sync
* Passwords on Firefox sync
* Google Fi is my carrier, and pulls eSIM when I log in to the app even without my old phone
* Google voice number is my main phone number. I don't lose access to incoming or outgoing sms or voice calls if I lose my phone.
In a pinch, I can buy a cheap prepaid phone and sim while traveling and be fully functional and reachable. I've had to do this before, and while I probably wouldn't go to the trouble for work, I feel compelled to be at least reachable for family.
I've thought about de-googling this further; photos could go straight into syncthing and I could port my # to a generic SIP provider that offers SMS. So far neither have seemed quite worth the trouble.
I've always felt very uncomfortable treating my phone as anything other than a rather overpowered thin-client.
Now the codes are with you and not in your phone or in the cloud.
I personally use Keepass for 2FA, Bitwarden for passwords. It's worked great for me so far, and I expect to stay with this setup for the foreseeable future.
