Esim was easy to install and use. Used in Turkey and Germany. Lost signal in some underground station in Istanbul. Otherwise it is very reliable service.

I used it in Hungary and Austria. While traveling by train, I sometimes lost signal in areas without houses, but overall, it worked without any problems. If you download the eSIM in advance, it's easy to use. I will use it again next time.

Visited Heidelberg, Rothenburg, and a few smaller towns. The eSIM worked perfectly everywhere, super easy to set up, and customer service was quick to help whenever I needed. Highly recommend it!

Surprisingly, this is probably the cheapest option on the market among other e-SIMs and is worthy of use.

It's more convenient than buying a new SIM card. If you don't know how to use it, try checking out TikTok. The internet might be a bit slow during calls, but replying to messages is normal.
