I gooyabinged Lenovo x100e. It is said "Bluetooth und UMTS gibtís optional." = UMTS-BB with build in Qualcom/Huawei-UMTS-Modem is optional.
So it would mean that you should read the .pdf-Book inside for it. And it is said that there would be a slot inside for a "normal" Mobile-Phone-SIM-Card that is reached by opening a part of the bottom-plate.
You would need to have a contract for this card that would cost you in Germany roundabout 20 to 40 Ä a month. Here there are two common rates :
If there isnot this modem build in then you would need a USB-Pen or PCMCIA- or Express-Card. USB should be able, I did not searched that exactly.
Then you should search for the /usr/bin "nm-connection-editor" and "nm-applet" for the set-up. Perhaps you need to look for a driver for the modem.
At my PUPPY-4.3.1 and #!crunchbang8.10.01+02 the internet works at Huawei K3715 without extra driver. It is said everywhere that there is Huawei e220+620 around. Perhaps these drivers work also at Ubuntu/Debian.
I have no transmission-monitor for the wave-speed. Somehow it seems a little bit slow but not extremely. IE8 at my WindowsV also is slow.
You need to have to google for the first and perhaps second DNS of your SIM-Card-Contractor (IntProvider) and for the APN.
Just type 'COUNTRYONTHEEARTH-TELECOM APN' at google search and you would find something like 'web.vodafone.de' or 'internet.t-mobile' and for the DNS '126.96.36.199' and '188.8.131.52' or just 'DNS-ADRESSE1: 184.108.40.206' for example .
If your are asked at the nm-GUI for a username and password then you can type in anything you like (crazy but it is so). Of course you need PIN and PUK-number. The posts #7 for Ubuntu and #5 for Puppy at http://www.linuxquestions.org/questi...tick-b-798202/
might help you in filling in the GUIs at these two Linux-OS .
Enjoy it !
