If you experience an “Unable to Complete Cellular Plan Change” error, then it could be due to:

* **Too many eSIMs installed: **Most devices support multiple eSIMs but it could be that you’ve exceeded the number for your device [here](https://skratch.crisp.help/en/article/can-i-have-multiple-esims-installed-at-once-1hm6x5c/). If so, you can remove eSIMs from your device as we’ve outlined [here](https://skratch.crisp.help/en/article/how-do-i-turn-off-or-delete-an-expired-esim-10qdu8v/).

* **Cellular/Mobile data is disabled**: Go to Settings to verify you have cellular/mobile data  

* **eSIM already installed**: **Confirm you haven’t already installed the eSIM by checking in the “My eSIMs” tab in the Skratch app**

* **Poor connection**: You need a strong Wi-FI connection to install your eSIM. Try again with a better connection before contacting our support if the issue persists
