iPhone 2018 Dual-SIM Slot Shown in Leaked China Telecom Promotional Poster

Apple's 2018 iPhone lineup is expected to witness an unveiling at the company's Steve Jobs Theater in California at a special event slated for September 12. All reports point towards the launch of three new models - an iPhone X successor with a 5.8-inch OLED display (iPhone Xs), a larger 6.5-inch OLED model (iPhone Xs Plus), and a cheaper 6.1-inch LCD variant (iPhone Xc). An image has now surfaced online that confirms the suspicion that iPhone 2018 lineup will include at least one variant with support for two SIM cards, i.e, with a dual-SIM slot.
