Update: They now have 5g working on the A32 5g
I bought the Cricket A32 5g from Cricket Wireless website, and even the picture on the website where I bought the phone shows the 5g symbol. My friend has the S20 5g and has 5g, so service wasn't the issue. Custimer Support tried saying it was. We went over the maps, and hey 5g is available. In the end the phone isn't on the compatibility list, and the 5g is locked on this phone and will not work on Cricket. There is no feedback area to tell Cricket about it, and when I tried to write a review it got moderated.
I posted a video with the conversation that I had with Cricket Support.
