I don’t tend to need much WiFi when I’m away but it is handy for looking up odd things on my iPad & also I normally tend to take my fire stick from home when away for odd little bits on wet days. The trouble is iPhone aerials are not particularly good & they think everyone lives in a city. I think from the tiny amount I’ve read something like aMiFi I think they call them & an aerial to go with it, obviously there’s the cost but having a SIM card it seems to need I gather but having one that doesn’t roll over at the end of the month. I only tend to get one week away & the odd extended bank holiday hence I don’t want to have a monthly sim subscription. I could use my iPhone as a hot spot if there was signal but often where were at the iPhone aerial is useless
