I have great WiFi at home, but not when we travel. So I bought a TP Link AC750 travel router. Model WR902AC. Several modes of operation, but it will grab free municipal or company (MacD, Walmart, etc.) signal, and you grab it from there. Other range extender might serve you well - but the wifi has to come from someplace. If they is nothing in the air for you, then it is either use your own data, get a better plan, see if your SIM can be swapped for one with better range - or go to places with free wifi.
