I stated this earlier and I think it bears some thought.. a few years ago I bought a 6+/6S+ (can’t remember which one) but the sim-free version had ‘new’ LTE bands in it. Supposedly, they were not in-use. This phone was a total PITA in North OC, CA. Areas where I was on the edge of having no service (on PCH South right before entering Huntington Beach) with previous iPhones I was dropping calls like mad on the new iPhone. I know VERY little about RF but I wonder if it’s a band-selection issue.They are not even close to having the same amount of coverage . Great if it works for you and you live in a major city but in rural areas T-Metro is still a joke especially in the deep south and plains . No 600 mhz coverage anywhere near me .
Anyone else have cellular problems who bought the Sim free version from Apple ?
I returned the sim-free and got the carrier version (which lacked the new bands) and service was back as it had been. Weak but not constant dropped calls in that area. It was my daily commute so I could ‘test’ a lot.
