# I Can't Top Up my eSIM

If you see an error when trying to buy a top-up in the WonderConnect app or on the website, your eSIM may not be compatible with the available top-ups.

We sometimes introduce new eSIM types to improve coverage or offer lower prices. When this happens, the available top-ups may only work with the new eSIM type and cannot be added to your existing eSIM.

## What should I do when I can’t top up my eSIM?

1.  Select **Get new eSIM** in the app and choose your destination, or find your destination on the website.
    
2.  Choose the data plan you need.
    
3.  Complete your purchase and **install the new eSIM**. Right after the installation, change the eSIM label in your phone settings. It will help you easily recognize the new eSIM.
    
4.  Select the new eSIM for **Mobile Data** and turn on **Data Roaming** for that eSIM. [Complete eSIM activation steps](https://help.wonderconnect.com/en/collections/5-mobile-data-activation) for your phone model.
    

The new purchase will appear as a separate eSIM in your WonderConnect account. It will not add data to your old eSIM.
