In the modern world of ESIMS, you do not have to worry about keeping an eye on the post-stamp-shaped piece of technology to use your phone, but there is a negative aspect: If you break your phone, leaves ESIM from a broken device to your carrier. A new update for Google Play Services suggests that Google can be an option in the form of eSIM backup as part of the forest subscription.
Android authority Google Play Services V25.16.33, dug in the latest beta version, and found references suggesting the SIM data backup. You can very safely rule on physical SIM cards here, as they are not affected by data wipes. It only leaves ESIMS, and it will definitely make it easier to transition from one phone to another.
Although it is important to remember that the code found in beta versions does not guarantee a feature, it suggests that it is something on which the developer is working. In this example, further evidence can be found in another update from March in which Google has also mentioned SIM backup.
If you break your phone or you want to move everything in a new device without relying on your carrier, the ability to backup an ESIM will be useful (assuming that you are allowed to do so), but it is likely to be in a case of somewhat niche use. If you need to reset your phone, Android devices give you the option to keep ESIM data. In that case you will just need to restore your data from the cloud.
On the other hand, phone theft is a common problem, and if you are already backing up continuously, you can disable the stolen device and make a new activated with all your favorite settings. This feature can be beneficial, but there is no guarantee when or even if it will see an official release.
