Hi there,
I had a s7 edge and rsap worked properly, now I have s8 duos and rsap is not working.
Is there any one who tested the app on s8 duos?

Dual SIM Samsungs don't support rSAP.

For us using dual sims.

Can we still use rSap by installing this app ... ofile.html ?

A short explanation: most Samsung phones support rSAP out of the box. My app makes sense for those who want to use rSAP with LineageOS, which has no rSAP support. Sometimes Samsung adds bugs to firmware updates, this may also be fixed with my app. So the phone must basically already support rSAP to make my app work.

Dual SIM Samsungs usually (always?) don't support rSAP out of the box. On a few models my app works a little bit, like the S4 Duos. But even there it has massive problems, like you have to reboot the phone after an rSAP connection.

I don't understand why Samsung does not support rSAP on Dual SIM phones, there is no technical reason. MediaTek phones work fine and you could even choose which SIM card should be used for rSAP. Although this is no longer the case with Android 6+ on these phones, at least on those I checked.

Thank you for the explanation. Guess I'll just bother Samsung instead because unfortunately I changed country and need my old SIM working.

Just so that others dont share my frustration.

I still rooted my phone and installed the trial app.
Eventually after several frustrating attempts, cleaning data in phone and in car I got to see the sim access profile in the car. But it just wont connect.

I wont go into the process of teethering via mobile phone because it requires usb connection wich my car does not have.

Oh well. Some day I wont need the dual sim phone.

If you are really desperate, try a MediaTek China phone. Of course the quality is not comparable to a Samsung S8, but they usually have at least 2 SIM slots and rSAP works...
