I have EE mini mobile wifi in my van - ok for phones and tablets. Not TV. If anyone knows better let me know. Connection can be bit hit and miss key is not to disconnect unless necessary. Takes several tries to get back on. Once established runs pretty well.
Not using for TV. Site has wifi only in clubhouse. My point is paying £30 a month for phone and tablet seems expensive. But could maybe use as a hot spot for TV as I have lots of unused data each month. But not savvy on setting up hotspots will have to enlist help from someone who is. Thanks for reply btw :-)
