Will Boost Mobile sell me a fake iPhone 5s?

I'm getting a refurbished iPhone 5s from Boost Mobile, it doesn't come in its original boxing because it's refurbished but I was wondering would they sell me a fake iPhone… I'm paranoid.

Not knowingly. But it would not really matter if they did, once you detected or found out it was not an official Apple Device, you would be able to return it to get an official iPhone of the same type from them.

Just make sure that you make a note of the ESN / IMEI and serial number of the phone you get, and make sure it matches all the paperwork that you are given for that phone.

No they won't

I'm sure it will be what it claims to be. They'd get in too much trouble with authorities if they committed widespread fraud like that.

No… & even if they did, simply return it.
