I am on T mobile and would like to switch to AT&T. Planning on getting an S23 ultra and trading in my old iPhone 11 for $830 credit. Basically will be adding $5 a month for the next 3 yrs not including the unlimited plan that I need to be on. Should i pull the trigger now or wait for the S24? I may not get better trade in credits next year or better deal for the S24 if I pass on this chance…
