Yes. Provided the device that you are using support dual SIM with an eSIM and the device allows for many eSIMs to be installed.
It is possible to install two (or more) eSIMs each with the same, or different, bundles and use them at the same time. However, our eSIM data bundles are designed to achieve the exact same functionality all within one eSIM. It is possible to top-up all of the regional bundles you would like to use on a single eSIM and the eSIM will work out which one to use data from based on the network you are currently using. This allows for those devices restricted to only a single eSIM to have the same benefits or for anyone to keep to just one nice and tidy eSIM.
