Sometimes, an eSIM can get stuck activating on an iOS device. This usually happens when you have installed an eSIM but haven't yet arrived at your destination country/region.  You can rest easy knowing that the eSIM is fully installed, even if it displays "activating" or "activation failure.". The activation process will finish when you reach your destination and are within the network coverage area. Here are some screenshots for reference:

Remember, even if the eSIM remains stuck on activating, you should still be able to use other features that don't rely on network connectivity.  Once you reach your destination and the device is within the network coverage area, the eSIM should activate successfully, and you can start using it.
