Yesim is an international eSIM provider with prices that fall in the mid-range.
In Germany, Yesim is one of the lesser-known providers—unfairly so, in my opinion, because Yesim does offer some very attractive rates for regions outside the EU.
While it’s hard to go wrong with Yesim’s fixed data plans, the company is completely opaque when it comes to its unlimited daily rates. If you want to know exactly how much high-speed data you actually get, you have to specifically ask the customer service hotline. The website only contains a very vague reference to a Fair Use Policy (FUP).
