If you have several eSIM bundles, there's a possibility to transfer the balance between them. All unused data from sending line will be exchanged then moved. Please note that due to the data price difference and the 10% processing fee, the amount of data may be increased/decreased after the transfer.
Currently, it's only possible by contacting our support bot, in the future, it will be a feature in your account so that you can do it at any time by yourself - support@keepgo.com (or use the chat on our website - https://www.keepgo.com/).
