This message is appearing too often for my liking!! Is there a problem with the network at the moment? Can't get signal anywhere. Also, at my work place I simply cannot use my phone since I've moved to plusnet, as there is zero signal. I've been there 9 years with another mobile company with no problems. It is very disappointing. Is there a way of getting a booster that would help rectify this, or should I just get used to having zero signal?
