Esim and physical sim. Possible achieve this?

JayJay

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?

Good day JayJay 🙏. I just wanted to clarify to what previous posters said if I may. You can have multiple eSIM cards installed on your phone in addition to a physical SIM card. You won't be able to use 2 or more eSIM cards simultaneously, however, you can swing between eSIM cards at any time.

I know that you can use two eSIM profiles simultaneously on a Pixel 7 running stock Android: https://support.google.com/pixelphone/answer/9449293

I would assume you can on GrapheneOS too, since the eSIM is a separate hardware component.

I hope somebody can confirm this!

This post indicates it might not be possible yet: https://discuss.grapheneos.org/d/4962-dual-esim-no-longer-for-android-13-beta-only

I went ahead and installed another eSim and can confirm it was possible to achieve what I needed. I can toggle between eSim but not run both same time.

JayJay Thank you for reporting back 🌷

Hopefully this becomes available soon

spiral Important to note that this may already be possible on 7th gen Pixels running GrapheneOS. I'm not 100% sure.

@JayJay says they tried it on a Pixel 7

spiral You're right, I missed that, sorry.

I'll ask around and see if I can get an answer.

What settings are required? I already had a data eSim for network calling over Cheogram. It is working. Then I installed a physical SIM and had my carrier port my iPhone number over to the new SIM. But when I open the phone settings, it says the number for SIM slot 1 is "Not available." I need to know what to do to get them both working. Any suggestions?

Hi wizzin,
do you have the data eSIM in SIM slot 2?

Which phone model you have?
Dual eSIM support is possible with Pixel models 8 and newer.
Dual SIM support is possible with Pixel models 7 and newer.

i have dual sim support (an esim + a physical sim) on a pixel 6.
it is not possible to have two esim active at the same time. on p6 but it seems to be possible on p8.

Eagle_Owl Dual eSIM support is possible with Pixel models 8 and newer

Pixel 7/7 Pro/7a have also Dual eSIM support.

Sorry, you are right, Dual SIM is also possible with Pixel 6 and maybe also on Pixel 5 (not all variants).

Two eSIMs active at the same time means Dual eSIM.
And yes, this is in practice/ real life only supported on P8 and newer.

Although Google had written at the time that dual eSIM works with Pixel 7 and Android 12/13, this was only possible in theory and with a single unofficial beta version in practice.
A dubious journalist, who constantly uses beta versions for testing but does not clearly mention this, then also claimed that dual eSIM works with the Pixel 7 (Pro).

As I wrote: no! Not in practice. Only theoretically!
I have a Pixel 7 Pro and it is really not possible to use two eSIM profiles parallel.
I can install more than one eSIM profile, but not using them parallel. Only switching is possible.

And this has nothing to do with GrapheneOS.
Doesn't work with Pixel-OS either. Tried everything. No chance!

Eagle_Owl Okay good to know. I have a Pixel 7a with two eSIMs activated at the same time.

Thank you, also good to know.
Then the P7a is the exception of series 7, because it has already a few newer technics of the successors.
