The easiest WWAN setup -- is found.

 

The WWAN card I want to choose -- supports both CDMA and GSM,  supports HSPA+ 21Mb  (not HSPA 7.2MB),  under $30.  Vender supports Mavericks

 

Then I found this one -- HUAWEI EM820U

Vender software -- http://consumer.huaw...8098&pro=EM820U

HUAWEI_DataCard_ClientSoftware_MAC-V200R003B015D02SP01C983(for Mac OS 10.9)

 

Installation and setup is easy,  Release the screws from the back of x201,  remove the keyboard and palm rest bezel.  Insert EM820U, (next to the wifi card),  connect red line to M (Main) connector, blue line to A (Auxiliary). put everything back.  download and run package of

HUAWEI_DataCard_ClientSoftware_MAC-V200R003B015D02SP01C983(for Mac OS 10.9).   it will install MAC OSX driver for EM820U and an application called Mobile Partner. 

 

After reboot,  there is new PPP device based on HuaWeiMobile-Modem is added into System Preferences ->Network.  I can connect to T-Mobile 3G network directly from there,   or using Mobile Partner,  both work for me.

 

Under USB, I found HuaWei EM820U,   but under WWAN,  there is nothing.

 

So far,  everything is straightforward, no tweak.

Patch CellPhoneHelper.kext is really easy, because Mavericks supports "0x12D1/0x1446 Huawei E367"

 

Huawei E367 (USB-Modem) and Huawei EM820U (PCI-Card modem) use the same chipset:  Qualcomm MDM8200A

 

So just copy the block of "0x12D1/0x1446 Huawei E367",  rename as "0x12D1/0x140C6 Huawei EM820U",  and update "idProduct" to "5132"  from "5190" --done:

I am just wondering what is difference between a dial-up modem and a WWAN card.
From end-user point of view and performance,  they should be the same. 
 
a WWAN card is also a dial-up modem, it is just supported natively by Apple KEXT (AppleWWANSupport2.kext or AppleWWANSupport1.kext or AppleUSBCDC.kext or AppleUSBCDCACMData.kext)
 
Am I correct?  or there are indeed differences from hardware itself (have 2 different working mode, such as  "WWAN card working mode" uses PCI Express 1.0 Lane,  but "dial-up modem mode" only goes through USB2.0 channel)?
 
If you check all those supported devices in CellPhoneHelper.kext. actually most of those devices hooked up via USB2.0 not PCI Express Lane. so an Apple Supported WWAN device is a USB device mostly. data goes through USB2.0 channel.   -- I am just feeling so confused.

Wow,  Leon -- I only have dial-up modem.   
How did you patch CellPhoneHelper.kext to get WWAN working?   For me, only show it as WWAN by patching CellPhoneHelper.kext,  but no signal strength bar, no WWAN device in Preferences -> Network.

I also test T-Mobile WWAN software:  T-Mobile webConnect Manager for Macintosh v2.06

http://tmodc.hcac.com/T-MobileRocket3.04GLaptopStick/Device.htm

The pages says It just supports T-Mobile Rocket 3.0 Laptop USB stick (4G/LTE)

 

But It works perfectly on Mavericks with EM820U,  it can read SIM message from T-Mobile SIM card.

 

webConnect Manager compact mode:

Full mode:

Read old message from my SIM card:

One thing I notice, T-Mobile shows the 3G channel is based on EDGE, not HSPA+,  (it also shows the signal strength, it changes from time to time)  Maybe it is because the free service from T-Mobile.   (free 200mb every month from T-Mobile :) )
