That was a backup option, but I’d prefer not to port my number back and forth between carriers. Thanks for recommending that regardless, as I did remember your post from a few months ago.Straight Talk Wireless sells iPhone SE (3rd gen, 64 GB) for $149. You'd need to subscribe to one month of Straight Talk service and then cancel and let it unlock after 61 days since original activation date. Then you can use it anywhere. I've done this about 6 times now for various friends and family. iPhone SE is the best option, IMO.
I found while shopping that all modern OLED smartphones cause headaches, and I still have some lingering headaches now. It’s difficult to pinpoint which devices cause the worst persistent headaches after a few minutes of testing, as the Motorola Razr and Razr+ caused sensitivity as well. iPhone 15 Pro Max was more or less the same as previous OLED Pro iPhones for me, despite some users having success. It’s really only iPhone 15 and iPhone 15 Plus that are more usable, but not immune from causing sensitivity. My draw towards iPhone 15 is that I want to enjoy using an iPhone again, I’m just not convinced it can do that if it causes migraines throughout the day.
