Hi there, the internet isn’t being very helpful so I thought I’d try here. I have the B315S modem with an external antenna and it worked very well at my old place. Just moved and seems I am on the cusp of 4G. Spark were pretty unhelpful and couldn’t reconnect me at my new address because I don’t have an address! I’m assuming it didn’t fit a box somehow. I’ve got the modem running but it obviously won’t work because the SIM is blocked now and Spark won’t unlock it to let me trial coverage here. When I search for networks manually it comes up with Spark 4G but I can’t connect with either the existing SIM or the one out of my mobile phone. I’m trying to change the preferred network mode from 4G to 3G to see if that works but the drop down is unresponsive. Any ideas why this might be the case, is it locked by Spark also? I know there is H+ and 3G floating round here and 4G it seems, because I have another Spark phone hardwired to a Yagi also on site. Cheers
