I will try a new post and new wording of the problem,
I have a dell e6420 xfr and it has built in broadband with dw5800 mini card,
I need to it appears to unlock this mini card as it keeps going back to version APN when I enter my att APN....so how do I unlock it?
Thanks for writing to Dell.
When you say unlock do you mean to remove the minicard. If yes, then please follow the below link and page 41.
Do let us know if it helped or is there something else you are looking for.
