While the band analysis may be interesting to you, the issue is just a customer experience issue to us. This isn't the 1990's and we're checking which bands work with which carrier and which tower. Apple made the iphone to work with all carriers. We're on Verizon, one of the largest carriers. If they desisgned a phone that doesn't work with Verizon efficiently, that's a failure on their part. We've also contacted our respective carriers and have been told there are no known issues with the towers at this time, so calling them with this band information is basically useless. It's really simple, if Apple is going to sell us a $2k phone, they better make sure it works with Verizon, and in the middle of a well populated areas like LA and Orange County, this isn't like out in the boonies.
Further, we can definately compare a flagship iphone 13 to an iphone 11, with a major carrier, in a major city, not having good service period. If Apple didn't consult, and work with Verizon to optimize for the iphone 13, that's also on them. The simple fact is if it doesn't work, we'll get a different phone. We've reported the problem, we don't need the explanation that isn't going to fix it for us, Apple needs to talk to Verizon if the bands aren't optimized for their phones, customers calling in about X tower possibly not handling bands 11 * 21 isn't going to get them to change it for us. Also 2-4 bands difference out of 24 bands, based on population change, iphone adoption vs other phones, its UNLIKELY that the band efficiency is the issue, and unlikely the issue on every tower in southern california.
We were on ios 15, we'll try 15.1 now and report back.
