I had visited Hungary for my family function for hat I had purchased esim and it was working really well I had used it for 12 days and I am really happy with the service of it.
I have used it many times in Germany and Switzerland and the coverage is very good. LTE speed is available and the offers are sometimes better than the ones from the national providers (such as Vodafone and Telekom). Additionally, customer service is excellent, they have been extremely helpful each time!
I bought one of these last fall when I was in France and Switzerland for a couple weeks and it worked so well I bought one again when I was headed to Germany for a couple weeks this spring (just as COVID was hitting Europe and America). Once again, it worked perfectly.
My significant other bought these for use during our special first night. They were awesome! We utilized them all over Europe and didn't need to get new über costly SIM cards upon appearance.
Introduce was a breeze (we are utilized to it as we travel regularly out of the country) after arriving in France, and we involved them in Germany, Latvia, Estonia, Sweden, and potentially a couple of more nations. They didn't work in Russia, yet we anticipated that. It was a truly incredible buy and I can't suggest them enough!
