Expiry date
When does iPhone 7plus expire
Question marked as
If you mean when it was discontinued (it's no longer being manufactured) iPhones 7/7+ models were discontinued at the end of 2019.
If you mean when it cannot receive new operating system updates, nobody here (just users like you) can give you an appropriate answer (most likely that model, firstly released in 2016 is reaching the critical point of updating capabilities, because of hardware incompatibility). You'll be able to keep on using it, but you might not be able to update it in the next future.
