Xperia 1 III now a Verizon-only phone
Don't buy the Xperia 1 III even through it's often advertised as a non-carrier US model. MyXperia 1 III is now losing compatibility with T-Mobile. It shows 5G or LTE but has no connectivity. Sony supportsays the phone works only with Verizon and won't discuss further. As far as I can tell without root access, it's trying to use SA 5G bands and aggregations that Sony hasdisabled in the Qualcomm firmware. Turning on 5G in downtown Sunnyvale California kills connectivity. It works only intermittently when forced to LTE.
