Hi Davidbec,

I am not a specialist about this hardware. Sorry.
EDIT01: If you have a posibility to make a
picture closeUp about a SIM card connection into S1080
for have a infos hardware (number and text and serial, made from etc...) If needed, remove a actual card on the connection.
Otherwise,
I suggest strongly see the forum :
http://forum.tabletpcreview.com/tablet-pc-life/42919-gigabyte-s1080.htmlAnd make a new topic about your situation.
A poster Trent make a good article and picure.
I suppose I help you more than me.
Your are welcome to forum for share infos here.
Thanks for your comprehension.
