Securing oneself when disposing a mobile phone

It's easy to step up and dispose of or trade-in a mobile device.....but what about all that confidential and private "stuff" on that mobile device?    Read on (from AppleInsider)..."Make sure you remove all your personal information before you sell or trade your #iPhone in because if you don't, the consequences can be creepy and dangerous as one Ontario teenager discovered. AppleInsider recounts the tale, and shows you how to avoid the same fate.There are those of us who hang on to our old iPhones and build up a stash of them for no reason that we can quite justify. More often, though, we can see our outdated devices as being cash to put towards a new phone. When even a broken iPhone is worth something in trade, you have to be tempted.You should do it, too. Not only could you save some money but you're getting someone the opportunity to own a cheaper, used iPhone. Just don't give them anything else by accident.In the fall of 2017, Ontario teenager Natalie Hall's iPhone 5s had a shattered screen and appeared broken. She traded it in and got a $11 toward the price of a replacement. That's hardly a fortune, but it's money coming in rather than going out and it appeared to be for a phone that was truly useless.In mid-July, Hall got messages from a man including this piece of prose: "All data is in the phone your to sweet your sweet dogii pic and your friend your tooooo to sweet plz join friend ship with me."This man was in Dubai and had bought stocks of old iPhones. He continued to press Hall to add him on Facebook and when she wouldn't, he did it himself. Right there on this discarded, broken phone he went into her Facebook account and accepted his own friend request."I was overwhelmed," Hall told CBC's Nicole Brockbank "It's creepy having your pictures and your contacts and your social media, text messages —all of that kind of stuff —out there with just a random stranger."She changed all her passwords. The man has since told CBC that he's sorry for disturbing her. He claims to have now wiped the data from her phone.Hall had no reason to suspect there could be a way to get her phone working again but now that you know, there are some emergency steps you can take. And, there are also precautions you can take when you ever sell on any iOS device.Even if you can't use your phone, you can safeguard your data. For instance, Apple does let you remotely wipe everything using Find My iPhone from another iOS device. That has to be enabled: if you've never switched on Find My iPhone or you've actively switched it off, you can't remote wipe.You can still do things such as changing your Apple ID password. Then if someone gets into your phone, they won't know that new one and won't be able to use, for instance, your Mail to send messages. If someone has access to your mail, they also have access to every bank account or store login they can find: every login offers to email you a replacement password. Similarly, you can go to icloud.com and remove your Apple Pay details, you can de-register iMessage from the device. This all helps but nothing is as good as completely wiping the iPhone before you hand it over in trade."
