Where sim card position in m400 - Toshiba Portege M400 PPM40U01000E Tablet PC
Only a select few (very few) M400's have a 3G wireless module, and from what I understand they do not use a Sim Card as they use CDMA technology. You can tell if your unit has the 3G unit with several different ways.
A. Check the device Manager
B. Try and install the 3G power management driver, and see if it loads.
C. Check using Toshiba Utilities if installed
D. This is the hardest way, but the best. Remove the keyboard, and if the 3G unit is installed, it will be at the top right hand side of the case under plastic film. (I have had three M400's, including the top of the range one that I am writing this on, and I have never seen a 3G unit).
If you do have the 3G unit installed, look for an ESN number. You should then be able to then call Verizon and have the service activated.
