[WPCentral Question]

While trying to tether my Lumia 630 (with two SIM cards) to my laptop (both under Windows 8.1), I realize that I am unable to put on internet sharing ("there is no mobile data connection to share at the moment", while I do have internet access). Also entering "access point" under settings for internetsharing is impossible. Can you help ?

I do not fully understand your question so here is some reply which may help.
Your mobile phone can not "tether" a wifi connection.
You can however use your "mobile" data to share. In this case your mobile data will be used to "make" a "wifi signal" and with your laptop you can connect to this "wifi" signal.
But what can be is that your provider disables the "sharing" of mobile data.
