I will be travelling to South Korea. I already have installed a physical simcard and dataplan with my main number.
I have an e-sim which I enable from time to time (US number/dataplan) which is work related.
I now want to purchase an E-sim for South korea with dataplan only to be enabled the whole time during my stay there.
While I am in South korea I will disable dataplan for my main simcard but I still want to be able to receive phonecalls.
Is this possible to achieve using GrapheneOS ? To have 2 e-sim installed same time as physical sim is.
And switch dataplans per simcard?
