I'm looking for a Dell Wireless Mobile Broadband Card for my Dell laptop which is compatible with my network and specifications.
Are there any cards which support:
WCDMA/UTMS 850, 900 AND 2100MHz with HSDPA of at least 7.2Mbps (also HSUPA or HSPA+ would be better)
XPS M1210 Laptop
The closest I've found so far has been the Dell™ Wireless 5540 HSPA Mobile Broadband Mini-Card which I'm not sure if it is supported by my laptop, and doesn't support HSPA on 850 or 900 MHz according to it's user guide, and I would like to find one that does.
