I'm trying to use my built in 3G modem in my T420.
I'm running the "Launch Lenovo Broadband COnnect" from "Lenovo ThinkVantage Toolbox".
I'm located in Sweden but in the dropdown box for "Provider" there are none listed.
I'm trying "Other" but it fails with a message that I need a proper SIM card.
My provider is Telia and my SIM is inserted.
What gives? Please advice.

Are you sure that your model got 3G? Some models are WWAN upgradable which means you have to buy and insert the 3G adapter. What is the model/type of your T420 (XXXX-YYY)?
Do you see the 3G adapter in device manager and no missing drivers?

I have T420, part number 4180RN4. On back side, close to battery there is a simcard port (just like on this image http://support.lenovo.com/en_US/downloads/detail.p
I do not have any 3g device in 'device manager'. Im using Windows 7 Professional 64bit.
How can i check if my T420 do have 3g device? Is it possible that even I've got SimCard slot there isnt any device which support it ?

I've got a T420, TYPE: 4178-C7G....
I've inserted the sim card into the slot behind the battery, buy not getting anything? I really thought this laptop had built-in 3G, how do I find out if I need to buy the additional hardware to get it set up?

You need one of these WWAN cards for T420:
0A36185 - Gobi™ 3000 Sierra Wireless EV-DO/HSPA WWAN Minicard - http://shop.lenovo.com/us/itemdetails/0A36185/460/
0A36186 - Ericsson HSPA+ WWAN Minicard (F5521gw) - http://support.lenovo.com/en_US/product-and-parts/
Check your Device manager > network adapters.
Anyway, I have looked on lenovo.com/support page:
i5-2540M(2.60GHz),4GB RAM,500GB 7200rpm HD,14in 1600x900 LCD,1GB NVIDIA N12P-NS1,CDRW/DVDRW,Intel 802.11agn wireless,Bluetooth,1Gb Ethernet,UltraNav,Secure Chip,Fingerprint reader,Camera,6c Li-Ion,Win7 Pro 64
I wonder if your unit has WWAN antenna or not, there is no "WWAN option" or "WWAN ready" mentioned in the list.
