Why not also suggest a higher Xperia Model, Xperia 1 (V or IV), or Xperia Pro (IV) for the variety of bandwidth 4G and 5G that these models include?
Some of us will greatly benefit from more spectrum of bandwidth, especially those who are in the USA.
Compare Sony Xperia 1 IV with Xperia 10 IV bandwidth, and you will find Xperia 1 includes more channels (if the term is correct). Or even look at Xperia Pro Network specifications.
I do not think ‘affordability’ of a specific Sony Xperia model, should be a limiting factor in canceling a more functioning and able phone regarding the phone’s cellular network connection.
I do have Sony Xperia 10 III, and it is not dependable, nor able to use it in all places compared to another Android phone I do have (Samasung). At this moment, my Sony Xperia 10 III is off the cellular network, in a ‘farmish’ area, and cannot receive or make calls, and I am using my Android phone to do so (Samsung).
