I was looking into the next iPhones to see what type of cellular improvements we could expect seeing as the intel Modem in the iPhone X was while adequate not exactly class leading. Luckily the next modem “Intel XMM 7560” is going to offer a wide array of the latest cellular tech such as 5x carrier aggregation and support of 35 bands amongst some other improvements as well.
