What's the difference between existing roaming and the XPIN network? Is there anyone who isn't curious? ㅡㅡ Existing roaming is a linear increase in usage = linear increase in costs. XPIN adopts a structure where: - AI continuously suppresses the average cost, - network revenue is generated from the difference, - and that revenue then covers user costs. Therefore, without the AI network transition, XPIN might have remained a "cheap eSIM service," => but it would have been difficult to establish a sustainable network structure, even with PayFI. XPIN isn't simply an eSIM service; it's a network that redesigns the communication cost flow based on AI. It's more accurate to say this. Furthermore, because AI continuously selects the most efficient and accessible network, it's much more convenient for users. In Japan, unlike Korea, it's incredibly inconvenient to use a single carrier and travel around, but this problem can be solved. It's not just about saving money, it's also about efficiency.
