 You can purchase additional data, which never expires. For me, it was the obvious choice for travel. I use WhatsApp to communicate, so all I need is the data. Yes, I did talk about the Solus. I used that when I was in Berlin. I tested it, and it worked great. I had the 5G model, which I think is more expensive than the one you got. But yes, Solus, if you want your own hotspot.
