Keep us updated. I'd be interested to know if you get this back to its original owner. I know I would be thrilled if I lost my phone and someone took the time and energy to make sure it got returned.
I looked around and saw nothing. In "Email" app, there are only a couple of old welcome emails from Apple dated more than a year ago. Nothing in text or call logs. Nothing in Safari or Maps. In fact, there were no user added apps at all.
Whoever had this before used
"First Last" as his or her name when setting up this phone.
It only has 16gb. Based on the model number shown in settings, I believe this was originally sold in the
UK, by a company called
Vodaphone. When I Googled the model number, Vodaphone kept coming up in the results. (although, according to Siri, the country where I found this phone was more than 6000 miles away from the UK)
Then I went in to reset the phone to factory default. It went fine and I created a new Apple ID(didn't want to have this phone linked to my existing Apple ID). Now everything seems to work fine. It even updated to the latest iOS without any issues.
I tried both my T-Mobile and Tracfone prepaid SIM cards. Voice and text both work fine. Can't get data to work with T-Mobile SIM card. Using Tracfone SIM card, it picked up AT&T 4G LTE just fine and I got speeds of almost 20mbps, which is normal for inside my house. Tried Verizon SIM card, didn't work(obviously

).
There is one little issue.. the speaker seems kind of muffled/squeeky.(compared side-by-side next to my iPhone 7 and iPhone SE, playing the same YouTube clips). I've never had an iPhone 6, so I don't know if that's normal or not. It reminds me of when I dropped my Samsung Galaxy S6 in the water a couple of years ago.
Anyway.. now that I completely wiped it clean back to factory default, if I started using it, there is zero chance that the previous user can see what I'm doing, right? (just want to be double sure)
