Should i get a refurbished iphone 5s?

I saw it really cheap on groupon but I've never had a refurbished phone so i don't know what would be wrong with it

First if all, refurbished phone are mostly from oversea which has very low 2nd hand trade value like in China. First, please don't buy online as we can't spot fake iphone. 2nd, if you buy from store, do ask mobile expert go with you for check up.

I have purchased refurbished phones in the past. But they were directly from my cell phone company Net10. I would not purchase a refurbished phone from someone else.

If it is refurbished, then it may well be as new, or have only very minor marks on the casing. That's especially true if this is a groupon offer. The things you need to be concerned about are, 1) what are groupon's terms regarding returns if it isn't in good, clean, working order, and 2) is it unlocked, because a locked iphone either has to be jailbroken (cheaper but not entirely great), unlocked, which is very expensive to have done, or used with the carrier it is locked to.
