In response to this, mobile-internet operator E Mobile is offering a special plan for its Pocket Wi-Fi hotspot-caster, which runs at a whopping 42 Mbps and can be used anywhere and with any Wi-Fi device. Entering a two-year contract meant a discount of about 10,000 yen (£83) on the Vita itself, off the retail price of 24,980 yen (£207) for the Wi-Fi model and 29,980 yen (£248) for the 3G model. Many stores hammered this service hard as customers lined up.
