I think the others are going to go faster than you think...Probably not much further than 2020 (2 years). T-Mobile is already re farming their older 3G space... Neville Ray had said in the past that he would like to follow Verizon's shut down date not too much further than what Verizon's is. AT&T just shut their 2G down in January and is now eyeing 3G's deadline. They have not made a date public.

Companies are going to be paying fees to Qualcomm anyway given how many patents and licenses they own for 5G-NR too. Also Qualcomm's integrated modems in their chipsets are better than anything else on the market so I'm in no rush to replace them. Samsung's Exynos chipset wasn't the best compared to the Snapdragon 845 on this most recent round of flagships. It had battery life problems and slightly worse performance despite being the better chipset on paper.
