I used several Samsung PCS phones. The others, made by LG, Hyundai, and some other much smaller South Korean phone makers. Now I have LG LP-2100 PCS phone, with built-in digital camera. I wanted the newest Samsung or LG with 1.3 mega pixel camera but they were not available for my LG Telecom service. I’m LG Telecom user since 1998. My first mobile phone used Hansol, now part of Korea Telecom, in early 1998.
I’ve spent more on PCS than on car and transportation.
In South Korea, both cellular and PCS exist, the cell service monopolized by SK Telecom, an SK group company.
