I want to install Instagram app on my phone but it not going through

Please try updating your iPhone first. Select Settings > General > Software Update. If your phone is eligible for an update, you will be prompted to do so.

Instagram requires iOS of 14.0 or higher. Unless you can update your phone past that, you will not be able to download Instagram.
