There are around 5-10 different variants (including carrier based) in the same models, having different prices.
I can confirm that no one having a really good 10/10 condition S5 LTE (G900F) sells for less than 30,000/-.
There are many carrier based, 3G version or refurbished phones that cost around 25,000/-.
Well said. It could fetch upto 20,000/-.
I visited market to get S5 for my friend and I was so pissed at the junk available that ruins market value of non refurbished phones.
