TravelTalkOnline Forums Travel and Vacation Forums World Wide Travel How reliable TooSim is in Europe?

Hi everyone.
I’m heading to Europe next month with a friend and looking at TooSim for navigation and train tickets. We’ll be driving between Germany, Italy, and Austria. Airalo felt overpriced for what we got, while TooSim has more pleasant prices, but we're not sure if they're reliable enough. Thanks in advance.

I haven't used TooSim, have used Airalo but agree they've now become expensive. My next door neighbour depart on a cruise to Europe and Morocco on Monday and I've suggested he tries this... https://esim.sm/en/travel-to/europe . I'll let you know in about 2 weeks how he got on.
