I am looking at a car that will take a micro sim for Nav and traffic. I cannot find a deal that gives me a SIM that has say 100Gb on it that I can pay for once and just leave in the car system. It can also deliver Wifi data to my kids when they are in the car.
Anyone do this and have a suggestion? To be clear I do not want an ongoing contract or a giff gaff type setup, I just want a SIM with a ton of data on that I can top up in say six months when it dies.
