A phone is simultaneously a communication device, authenticator, camera, wallet and store of personal data. Choosing a handset is therefore also a choice about updates, accounts, recoverability and control.
Look beyond camera and storage to support, battery, repair options, SIM or eSIM, accessibility and how easily data can later be moved to another device.
Preferably for as long as you reasonably expect to use it. Check the concrete update commitment for the model, not just the brand. A technically good phone can become impractical when security updates stop early.
No. eSIM can be convenient, but it moves more control into software, provider processes and account access. A physical SIM is easier to move between devices. Which option is better depends on the use and recoverability you need.
Contacts, photos, messages, authenticator codes, banking apps, password manager, email accounts, local files, SIM or eSIM and app-specific exports. Check which data is actually in a cloud backup and which exists only locally.
Yes. Digital and digital self-reliance are suitable starting points.
