Galaxy S20 Ultra and rSAP - 5G SIM (o2 uk) does it work?

Hello Everyone
I have a S20 Ultra, and my car uses rSAP (Remote SIM Access Profile) to connect to it via bluetooth. The SIM I have from O2 is a 4G sim.

I tried a few weeks ago an eSIM from O2 and it deesn't allow the rSAP functionality to operate in my Audi, only a physical SIM will.

As this is important and crucial that the rSAP works, can anyone confirm that a 5G SIM, and specifically an O2 UK 5G sim will work with the rSAP function in the phone/car. I am considering upgrading my contract, but don't want to if the rSAP does not work.

I'm not wanting to know if 5G will work in the car (the car needs to have a 5G cellular interface to do so which it doesn't have), I just want to know if the 5G sim will operate fine on 2,3,4G networks in rSAP mode in the S20 on O2.

 

Thanks any confirmation appreciated.

I know this reply is a bit late but an S20+ with a Vodafone 5G sim worked with my Porsche PCM 3.1 RSAP.

Hello everyon

Yes, I have tried this now.

 

It works with a 5G SIM but not an eSIM.

 

There can also be problems however if you SIM isn't provisioned correctly with your service provider, where upon disconnecting from the car, your phone won't connect to 3G until an IMSI handshake has completed (turn phone off or eject and reinsert SIM)

 

But 5G SIM works fine.

Are you pairing from the car to the phone not the phone to the car?
Also make sure SIM cards is allowed in the phones Bluetooth settings

I had no problem setting up my s20 plus on my Audi MMI which requires rSAP. Phone connected in "remote SIM" mode and everything works.
