X61s with Middlenon BIOS. What 3G WWAN card the best? Gobi 2000?

As your X61s is running the Middlenon BIOS, in theory you should be able to install any legacy and current WWAN cards available (with Pin20 covered?). As I do not have an X61s, but assume similar experiences with cards I have installed within several T60's - The following unlocked WWAN cards worked with no prob's with T60's that supported the internal WWAN mini PCIe slot - (with modified BIOS, covering over Pin20, sim card slot & relevant antenna's)

Sierra Wireless MC8775 (Generic, HP & Lenovo branded), MC8780 (GPS Enabled) & MC8790 - Option GTM378 (GPS Enabled) - Ericsson F3507g (Lenovo branded) - These cards worked well with all UK mobile networks

My personal favourite's are the Huawei EM770 & EM770W - Very fast DL/UL with excellent sensitivity in poor signal reception areas - both support PCM voice over USB (with correct firmware), enabling voice calls through the thinkpads internal mic & speakers or via bluetooth headset. They also support simultaneous Data & Voice providing your Sim & mobile network support it - Recommend them!

Currently I do not have any Gobi 1000/2000/3000 or Ericsson F5521gw WWAN cards to test, but may get access to them possibly early next year etc.

Before buying any WWAN mini PCIe cards, do make sure the technology & frequency matches your country's network(s).

Where I can find new firmware for Sierra MC8775 (up to 7.2Mpbs)?

Sorry to bring this old thread back, but I need a link for the updated firmware for the Huawei EM770 UK version and I also need to know how to enable voice. My EM770 came unlocked if that may help. Thx in advance.

Welcome to the forum -

See link >>> EM770 + Mobile_Partner_11.302.09.01.539 = Voice Enabled - If you get stuck, there is a "live chat" and faq links on http://www.dc-unlocker.com/

Thx Peak.

It worked, I just updated the firmware and installed mobile partner and I was able to make calls. Once again thx.

Great news! - - Looks like your EM770 was already voice enabled (?) - Been using this card (Voice enabled) in my T60p (see signature) for 2+ years on 3UK - Works fast and smooth.
