Simtex is a fairly new company in the eSim market with very few user reviews. However, it's important to note that they are a legit telecommunications company, with offices in Israel and the United Kingdom. They've recently launched their eSim service. Simtex is a provider of eSim technology that offers eSim data plans for various countries throughout the world. They partner with various network operators in other countries, to provide access to mobile data on their network. This Internet access doesn't include any data roaming charges, so users get to browse the Internet as if they have a local sim card. Their eSims are data-only, which means that users don't get a phone number to use for making calls and sending/receiving texts. But that's the case with most other international providers as well. Please note that these details may vary over time and it's recommended to check for the latest ones.
