For many users, the following technical feature is important when purchasing: rSAP. This is the so-called "Remote Sim Access Profile".
A car with an integrated telephone module, for example, can access this profile. Then only the Sim card of the smartphone is used, but reception etc. is provided by the car phone.
The advantage of rSAP is that you have better reception in a vehicle, as the antenna is usually mounted on the outside of the car. Does the Samsung Galaxy Note 9 support rSAP?
Since the Samsung Galaxy Note 9 is a dual SIM smartphone, rSAP is unfortunately not supported.
If you can't do without this feature, the Samsung Galaxy Note 9 won't be shortlisted.
