I'm not sure it will work for you but it's a trick I used on my one s with an AT&T SIM.
It will look like this and it persists beyond a reboot or WiFi on/off.
wich type field?authentication type? or APN type? im not sure what im looking at with your pic.
im using an international One on t mobile,and my data works fine,with exception of when it comes back on it doesnt always pick up 3g/H data,sometimes it only picks up edge,but im assuming that may be becasue the refarm 1900 band may not be that strong here at my house.
out of curiousity,what data speeds do you get with the one s on ATT? ive used various ATT devices on t mobile,but never the other way around
to the OP,try toggling airplane mode off for a few seconds,then on. more often than not,that works for me,if data doesnt turn on,or turns on edge only.
