I know from searching I can swap my iPhone sim and put it in a 4G router when I'm away in the caravan. I get 100GB data a month so more than enough to stream Netflix onto TV when away.
My question is: Is it as simple as taking the sim out of my iPhone X and putting it in the router (I presume router would need initial setup?) Then when finished I take the sim out of my router and return it to my iphone? Does this change any settings or is it swap and play between each device.
I did tether the TV in the caravan to my phone but recently (since IOS update?) this is not always seen by TV when searching and disconnects hence I prefer the router idea.
