No, the iPhone 6s does not support eSIM. The eSIM functionality was introduced by Apple, starting with the iPhone XS, iPhone XS Max, and iPhone XR models that were released in 2018. Therefore, your iPhone 6s is not compatible with eSIM plans offered by carriers.
To use an eSIM, you would need to have an iPhone model that supports this technology, which includes the following:
- iPhone XS, XS Max, and XR (2018 models)
- iPhone 11, 11 Pro, and 11 Pro Max (2019 models)
- iPhone SE (2nd generation, 2020)
- iPhone 12, 12 Mini, 12 Pro, and 12 Pro Max (2020 models)

If you wish to switch to an eSIM plan from your carrier, you would need to upgrade to a newer iPhone model that supports this technology. The eSIM offers convenience by allowing you to switch between carriers and plans without the need for a physical SIM card.
