There is no way you can update your phone as long as you're using an "outdated" R-SIM. You have to upgrade your R-SIM first, but I don't think there is already an available version for iOS 9.0.1. That's the nuisance of using special SIMs like that. If you update it with the latest iOS, it won't be blacklisted (you will still be able to use it), but it will be locked to the carrier it is originally locked to.

Another way to update is to jailbreak your iPhone but just like R-SIM, you can't always get the jailbroken iOS with the same version as the non-jailbroken version.

The best way to keep your iPhone have the latest iOS version is to buy a factory-unlocked iPhone.
