I have a Celsius H240 that work fine with the optional mode take from Lifebook S6410...
I have also tried it on Celsius H250, but after drivers installation, when I start 3G Watcher, It say that "no able to find any hardware"... If I check in the system properties --> hardware device, I can see that UMTS module isn't istalled regurally... Do you have any idea?
I take umts module directly from Sierra Wireless, the same type & model that is installed in other FS laptop. (Sierra Wireless MC8780)
I must brought it directly from Sierra Wireless 'cause FS say to me: <<If you want an UMTS Module inside laptop, you must buy laptop with optional module... After you can't buy optional mode>> Strange but real... Why I can't buy a UMTS Module Officially in FS Store directly?
Same module work fine in H240, Lifebook S6410!
