The iPhone 6s Plus came out in 2015. Yes, it still works as a phone on most US carriers.

Key takeaways

The iPhone 6s Plus still works on most US carriers.

It's stuck on iOS 15.

Check the IMEI before switching carriers.

The quick answer

Calls and data: yes on most US carriers
Software: iOS 15, no longer updated
Most apps still install, though fewer each year
Good as a backup or budget phone

Calls after the 3G shutdown

It supports VoLTE, so calls still work on most carriers. Its last major update was iOS 15, and many apps now require something newer.

How to check yours

Find the IMEI: dial *#06#, or look in the phone's settings or under the battery.
Enter it in your carrier's compatibility checker. Every major carrier and most prepaid brands have one.
If it isn't supported, it's usually missing approval for VoLTE (calls over 4G), which every US phone now needs.

Who it still works for

Anyone who wants a capable phone for very little money, or a dependable spare.

If you're replacing it

A refurbished iPhone 13 or newer still gets current iOS and costs far less than it did new. For a new phone on a budget, several carriers give away an iPhone 16e or Galaxy A-series phone when you switch. Pair it with a low-cost plan such as Mint Mobile ($15 a month for 6GB on a 12-month term) or Visible ($25 for unlimited, taxes included).

Free phones when you switch

Current offers from Metro, T-Mobile, Verizon, AT&T and Xfinity.
