Would the Unlocked international Galaxy S 3 work on the Go Phone $50 Plan? Since it's not in their database it wouldn't be a problem right? I'm on ST now but wanted to have backup just incase they decide to get rid of me for using to much data.
Previous experiences indicate that if AT&T is selling a particular smartphone model, even unbranded versions and versions for other carriers get flagged and locked out of the free data of the $50 plan.
There are also precedents of phones AT&T hasn't carried at all that are now being flagged as smartphones *cough*Nokia N9*cough* so I wouldn't spend the money a GS III costs if your only intention is to get the free data from Go Phone's $50 plan.
