OP. Your only option is a third party unlock service. Maybe you'll get lucky as historically Sprint had been difficult.
R-SIMs are SIM Interposers. They fool the phone into thinking it's using the native network (in your case Sprint) when it's not. But they are not unlocks.
The problem with R-SIMs (and Geveys) is that they are often picky about which firmware you are using and a lot of them require the iPhone to be jailbroken first.
Lastly, Sprint's policy towards international unlocks has changed recently. Sprint feels that their international plans offer enough to their customers so they now deny international unlocks unless the phone is paid off.
There is a difference between an international unlock and a domestic unlock. The domestic unlock automatically includes the international part. International unlocks do not include domestic unlocks.
At one time swiftunlocks.com was offering Sprint unlocks. You could maybe try them as well.
Thanks, this seems to be the only way out. Have you had any experience with swiftunlocks before?
Gevey/R sims currently work on iOS 11.x without jailbreak but what you told is 100% correct - apple could render it useless in a future update.

It is extremely low cost. Check yourself and ignore people who have no idea what they are talking about (the guy below who clearly made his account JUST to reply)
- They are charging me $0.00 for every text, FREE TEXTING
- They are charging me $0.00 for data, FREE DATA (2G) You can pay for higher speeds but in most countries wifi is widely available
- They are charging me $0.20 per minute, talk is expensive but you can use 2G to chat through WeChat or Skype for free.
You are absolutely clueless, good job making an account just to bash Sprint.
Here is an example of their pricing in some asian cities:

'Sprintsucks123' is an ignorant moron who clearly had a bad experience with Sprint and wants to spread fear uncertainty and doubt. If you are going to a remotely developed area, you will have plenty of Wifi, can use ANY one of hundreds of calling apps, and your service will be free. Data will be slow at 2G but again all developed areas have plenty of Wifi. Additionally, undeveloped area's of most asian countries have poor service and reception anyways so getting a plan there wouldn't be any different.
I don't work for Sprint, but have direct experience with their international plan and I am satisfied.
Why even bother commenting when you are going to jump to conclusions with my username? Lol
I'll be going to India where the cost per month is ~$5 (1gb LTE data everyday along with unlimited calls and texts) apparently first time users get 2 months for free. So basically ~$5 gets me 1gb 4g LTE + unlimited texts & calls for 3 months (which is approximately my period of stay)
Now tell me who is the moron here?
(Look up "jio" if it sounds too good to be true)
Just because you're satisfied doesn't mean everyone needs to be.
I would go with what seems to be the best option for me and you should do the same too instead of talking out of your ass.

Tell Sprint to unlock it only for international. They will unlock it for you.
They denied since it's on contract, which is totally understandable.
