Chinese resource 21st Century Business Herald published information that Apple may release iPhones with dual-SIM support. The long-awaited event could take place this year.According to the published information, the new iPhones will still have one SIM-card slot. The second card will be a built-in Apple SIM, which is able to switch between different mobile operators. Curiously, such cards are not available in China. For this region, the Cupertino giant will supply special versions of smartphones with two slots for regular SIM. Perhaps in Russia the same versions of the iPhone will be supplied, because in our country Apple SIM is also not available. Recall that the new iPhones will be announced in September, at the annual press event. At that time we will know all the details about the new generation of smartphones from Apple.
