Apple iPhone 8 Plus
Verizon

Listing approved. Thanks for using Swappa.

Is it unlocked for any carrier?

It should work with all aside from T-mobile per the link. https://www.whistleout.com/CellPhones/Guides/Will-my-iPhone-8-8Plus-work-on-another-carrier

So apparently it will work on T-mobile as well, but it's missing Band 71 so some speeds may be decreased. This article explains band 71. https://www.maketecheasier.com/what-t-mobile-band71-means-for-subscribers/

Battery replaced by whom?

Replaced by Verizon total mobile protection plan.

Have you ever had any trouble with plugging in a Lightning cable, due to lint, worn contacts, etc.?

Also, is the scratch at all visible when the screen is on? In your photos so far, I can only see it when the screen is dark.

No issues with the connection. The scratch is not visible when the screen is on. The picture actually makes it look worse than it is because I wanted to highlight it for full disclosure.
When we had the battery replaced they actually commented that they couldn’t believe the excellent condition of the phone and didn’t notice the scratch until we pointed it out.

Hi Rachel... would you be willing to take $325 for phone?

Hi Kevin, price lowered for you. Price includes shipping and fees.

Yes, we'll make that work...Kevin W
