Then you're living on borrowed time, because 5G has been here for a while now. Also, 4G = LTE. My iPhone SE 2020 is my transitional phone. I'm waiting for the 5G network to be more robust before I make the switch.
In more ways than one 😆
I only bought a smart phone, because the 3G phone I had was being interfered with by somebody's network booster in my neighborhood. I had to go to 4G to get the network booster's icon off my screen. I bought an iPhone because I own Apple computers, and got the cheapest one Verizon had. I've hated it from the time I bought it, and only use it for phone calls and occasional text messages. I don't do anything else on it.
