One of the most anticipated features in the new iPhones of 2018 was Dual SIM support which has been a common feature in most Android smartphones. This feature was leaked in the iOS code base quite a while back, but got unveiled with excellent detail in the Apple keynote. Dual SIM was a feature which was limited to entry level or mid-tier smartphones until recent times when manufacturers like Huawei, Samsung, LG, OnePlus have been including Dual-SIM support even in their flagship smartphones.
