# Do top ups extend the validity of my eSIM?

Yes they do on Skratch! When you top up, you’re adding data to your eSIM and extending its validity. For example:

* You purchase a 10GB for 30 days 
* You’ve used it for a few days and now it has 5GB and 20 days remaining
* You top up with 1GB for 7 days 
* Your eSIM now has 6GB for 27 days (existing + top up)
