How to bypass iphone with activation lock?

So I have found an iphone here in our country which is vietnam, then I contacted the number of the owner that is found in the activation lock message but I can't contact him/her. As what I see in his/ message he/she is a Spanish. I have this phone 3 months since I found this. So my plan is to bypass the phone so that I can use it, but how can I do that? Any suggestion guys?

Can't do anything about that.

You are SOL, that phone has long since been reported lost (I have a feeling that is was stolen), so even if you could get past the lock, you would have a phone that could not be activated as a phone, can't connect to iCloud or iTunes, and many have minimal use as a Wi-Fi only device, which can't download apps from Apples App Store.
