Are similar samsung batteries interchangeable?
So, my phone model is an SM-S820L. I'm having trouble finding batteries for it, but have found a lot for model SM-G360P. It looks pretty similar, and I'm wondering if I can use the battery for that model in my phone. (Both of these are Galaxy Core Primes, I think, but SM-S820L seems to be a somewhat "rare" model, as a lot of places don't seem to know what it is...)
Also, do I need a SIM card to use the phone, or can I just work off WiFi?
