Bought a cheap ex corporate laptop: it has a W. WAN card fitted - and has a SIM slot, which currently has a blank in it. I am planning to remove the WWAN card, as I can replace it with a 250 GB mSATA SSD drive for about £50. I know not if the WWAN supports 4G, or is less able. Have not considered SIM only Mobile Broadband from the lappy, so before I remove said card, just thought I would check that I am not missing out on a worthwhile option. Any members using SIM only Mobile Broadband from an enabled laptop? Anything good, or bad, to say about it?
