The next iPhone is said to be the first candidate to incorporate a a second  data channel via satellite internet.
September 1, 2021: The next iteration of Apple's iPhone due out next month may include hardware that  will allow it to offer analternative channel for  Internet other than cellular 5G -- via satellite.This speculation was triggered yesterday by TFI International Securities analyst Ming-Chi Kuo who  said the new iPhone unofficially called iPhone13,  may incorporate a varfiant of Qualcomm's X60 baseband modem chip that  can support communication via satellite.
There is a divergence of opinion whether Apple will opt for the internet service from the geostationary  Globalstar system or go for the yet-to-come  low earth orbit or LEO class of satellite network of which  the Elon Musk-funded  Starlink and the Bharti Airtel-funded OneWeb are  best examples.
