This is why I don't save anyone as "mom" or "bff" in my contacts. I use their first name ONLY and add irrelevant photos to their contact id of cats or llamas lol. Phone theft can happen anywhere and y'all better be keeping your important stuff on a flash drive in a secure location at home with another flash drive with just your emergency contact numbers and such hidden on your person, just in case you lose your phone at a party and need to call your savior to get help getting home or whatever lol.
Trust nobody but you at this stuff. Use data instead of public Wi-Fi and a "private browser" or proxy for any emergency internet usage if you absolutely have to use free WiFi somewhere.
STOP filling out the "about me" or "owner" page on your smartphones with your real names, addresses, etc. That can be hacked and retrieved very easily. Don't trust apps that aren't verified. Don't click links you don't trust. DO NOT "rename device" at all! The hackers in public wifi places can see who is using the service and your device should not be named "Marina's iPhone ♡" because that makes you and easy target. Leave the generic name for your phone as is. It's not that cute. Personalization isn't always safe for sexworkers in general.
