I tried to answer this post & cloudflare popped up so it didn't post.
I used to move my H20 $10 pay as you go SIM from z222 flip to various AT&T smartfones, even a TF branded smartfone that ran on GSM or AT&T service. Calls & texts worked in the smartfones but data settings never updated. The z222 flip phone worked fine, it updated. The settings may be able to be manually updated if anyone out there has the current ones.
