I've had a few Android handsets for Private Cellular network testing. My go to is the S24 Ultra. I tried a Pixel device first, but the UI was poor so I moved to Samsung. I don't like all the Samsung installed bloatware, but it's easily mitigated. The S24U is a great device. There are multiple flavors, but I have the unlocked US one with both a physical SIM and an eSIM. I use the eSIM for my private cellular and the pSIM is a $10/mo T-Mobile data-only SIM. This S24U is more powerful than my iPhone 16 Pro Max (better cameras too). I really wish my company would allow us to use android devices with our MDM setup, but alas they paid for both devices so I can't complain.
