Does removing a Verizon SIM card unlock an iPhone 6s?

I recently left Verizon Wireless and have 2 iPhone 6s which I would like to sell. I wiped the phones and removed the Verizon SIM cards. Does this mean the phones are unlocked?

If they are still "locked," can I sell them anyway?

My iPhone has not been letting me delete my history, what should I do

Even though I'm 14 years old my mom set up a screen time account thingie on my phone-kind if like a experiment-. Recently I stumbled on some ADULT content and I'm talking XXX rated stuff. I did not mean to but it kept comin back! Now that i'm OK i went to delete my history on safari so that no one would see but the words were grey and nothing happened when I clicked on them. Please Help! My mom goes on my phone A LOT and so do my friends, I would be so ashamed if they saw! All the remedies online included putting the password into the screen time account and fiddling with that history but I don't know the password and can't ask my mom!

Is my friend lying to me and using me to pay for purchases on Apple?

I let my friend use my debit card because she claimed she needed it to update her iphone. Everything seemed fine until August when I suddenly started getting purchases from $0.99 to $35 but then it got worse the charges started adding up thus eating into my meager funds. When I confronted her about these purchases, she would come up with excuses saying her boyfriend's nieces and nephews made the purchases, or that our mutual ex made the purchases. She even claimed she removed my debit card info from her itunes account but then I continued to get charges from apple and when I confronted her, she claimed our ex made the purchases. She recently told me she called apple and even claimed they would give me a refund. I never got it. She even promised the purchases would stop but then I got two more charges from apple for $0.99 and $7.98. She also purchased icloud storage and apple music and told me i would only get charged for those only. Again, she promised I would get a refund for the latest charges but I'm afraid I may never get it even after she claimed it would take a few days. How can I get her to remove my debit card info from her apple account? I'm tired of these charges and am worried more charges will show up because I can't use my debit card without this problem in the way. Should I call the bank? I'm convinced she's lying to me and using me. I don't know if I can trust her anymore.

How to fix my iphone? - 1

My iphone has been dropped from table and after that its not starting up. If I connect it to charger only apple logo appears and gets stuck there. Sometimes the logo disappears with a red screen. This phone is out of apple service and I took it to a local mechanic. He said its a software problem but he couldn't fix it either. I tried hard reset but it didn't work. How can I fix this phone?
