I purchased an eSIM for my trip to Turkey. Unfortunately, nowhere during the booking process was it clearly stated that the connection speed was limited to only 5 Mbps. For my needs, this made t... See more

I went to Switzerland for a week
I went to Switzerland for a week. Local data plans are very expensive, and through Yesim I was able to connect a package for the whole of Europe and use it even in Austria, where we stopped for a couple of days. The connection took a couple of minutes, and the Internet worked even on the train in the Alps.

I bought a e-sim from this company…
I bought a e-sim from this company while traveling in Austria for a 7-day coverage. Service was okey while in the cities, not good when out on the road. What's really bad is that the company keeps on repeatedly charging me later 3 more times (26.10 Euro) without my knowledge. I had to work my credit company to get the charges removed. Sounds like fraud to me.
