Smartphone Resale and Flagship‑Killer Business Models Reveal Market Opportunities

Starting a resale business for used iPhones in the Czech market can require an initial investment of roughly 42,000 CZK to 105,000 CZK, depending on the range of models stocked. The most in‑demand devices are the iPhone 13‑17 Pro series, and sellers rely heavily on social‑media advertising rather than dedicated websites. Profitability improves with higher‑priced Pro models, while budget variants also find buyers.

OnePlus built its early reputation as a “flagship killer” by selling the OnePlus One (2014) through an invite‑only web platform with a minimal advertising budget of about 300 USD. This model eliminated intermediary margins and kept inventory low, allowing a launch price of roughly 7,400 CZK. Over time, added features and higher production costs raised prices, with the OnePlus 15 launching at about 24,990 CZK. The brand’s strategy demonstrated how low‑cost, online‑first sales can generate high volumes before shifting to premium pricing.
