    Do you have a WWAN card? – GabrielaGarcia Jul 12 at 1:21
  • @GabrielaGarcia and assuming s/he does, the follow on question is, does that WWAN card support the carrier s/he wants to use? IIRC most of those are Verizon-only – Android Dev Jul 12 at 1:26
  • @AndroidDev When I was in high school there were some Dell's (in Europe) supporting different carriers. – GabrielaGarcia Jul 12 at 1:31
  • Thanks for your comments, I don't know about WWAN card, but when I search for it I found this <laptopmag.com/reviews/laptops/dell-latitude-e7250> and there is nothing in Mobile Broadband, does that mean that I can't use the sim card on it ? – user905942 Jul 12 at 19:13
  • Typically all laptops of a certain model come with sim card slot, as it's cheap. All contain the wiring and antenna, but not all come with the wwan card itself. This may be bought as an addon. The output of lspci should tell us if you have a WWAN card. – vidarlo Jul 12 at 19:25

From the lspci output you provided, it does not look like your computer has a WWAN card. You can probably install one, but before buying, I would open the machine and verify that wiring for antenna is present. If you look at the picture here you can see a WWAN card installed at the upper left side of the computer.

Note that WWAN cards typically has to match a whitelist for that particular model. You should check which cards are delivered by default for your model. With a bit of luck, you can find it for a good price on eBay.

  • Thank you for your answer, does that mean that I can't use my sim card on this laptop? – user905942 Jul 12 at 21:27
  • I cannot see any wwan cards in the lspci output... – vidarlo Jul 12 at 21:34
  • please excuse me, I am null on this stuffs! wwan cards is necessar for using the sim card ? – user905942 Jul 12 at 21:57
  • Yes, the wwan card contains the actual radio transmitter that connects to the cellular network. – vidarlo Jul 12 at 22:00
  • Note that you can pick up WWAN cards for 15-20$ on ebay. Installing it is half an hour, and something you can do yourself. That's however slightly out of scope of Ask Ubuntu. – vidarlo Jul 12 at 22:14
