I traded my PS3 for a Sprint Iphone 4s. The ESN is clean and it's under warranty until OCT 2015. Would I be able to send it to my fiance in the Philippines? Would she be able to use it there? Thank You for any replies.
The phone would need to be unlocked first. Sprint will only unlock for international use, not domestic. So, for the Philippines that should not be a problem.
However, you do have a problem getting it unlocked internationally, unless you are a Sprint customer.
To unlock it you have to meet Sprint's requirements.
1. You must be a Sprint customer for at least 90 days.
2. All bills must be paid on time and in full
Then, Sprint will unlock your iPhone. If you do not or cannot meet these requirements then the iPhone will not be unlocked and your fiance will be unable to use it there.
There is no commercially available unlock. Meaning, there are no websites, no eBay stores or anything like that where you can pay money and obtain an unlock. If you could, the unlock would still only be for international use and Sprint prohibits any of it's iPhone IMEI/ESNs from being in the Apple unlock database (domestic).
