Just fitted a Kuma router with puk style aerial, teamed it up with an iqmobile SIM card EE , and pleasantly surprised! Easy set up , in fact plug and play, really quick WiFi connection, as opposed to O2 which I had previously, absolute game changer. The difference between a hotspot and router is immense, in my opinion. Ok no rollover and £20 a month for 100gb , but I do watch tv , Netflix etc most nights as I’m a full time motorhomer . Going to Europe September, so will let you know how I get on. Oh bye the way the light did come on!
