I recently did a rotation in South Korea and while I was there I bought a Samsung Galaxy S8 from Olleh KT who said the phone was unlocked and would work with any carrier in the states.When I got home I went down to the local Verizon Carrier and asked if I could get my phone switched over to their services, as i've used them in the past, and they told me I would need to most likely get my phone flashed. Is this the only solution, as there is no company around that flashes phone, or is there an alterante solution. I would really like to be able to use my good phone again in the states with verizon preferably.
