Welcome to Justanswer.com, my name is Dustin.
I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
The issue you run into at the 11" netbook level, is either it doesnt have a backlit keyboard, or it doesnt have a Sim card slot.
Only the higher end / more expensive models tend to have both a backlit keyboard and a sim card slot ( to allow connection to a cellular data network )
The good news about the higher end models is they are built to last and a bit more rugged then the bargain models. This model for instance, http://amzn.to/2b4p30e
Has the sim slot, a backlit keyboard, and a standard 3 year warranty since its considered a Higher end HP. You can purchase a used / like new model from that page for 525$ thats been upgraded to 12 gigs of ram. Thats a steal at that price range.
Speaking of price range, if you were willing to go with a 13" model, we could probaly find a backlit keyboard + sim combo a bit cheaper. But if the price isnt prohibitive that used model saves you about 1500$ over the cost of a new 12 gig EliteBook Revolve 810
If you have further questions, let me know.
