Poor reception and customer service
Poor reception in both Budapest, Hungary and Berlin, Germany. I would be on SOS or "E" 50% of the time. I reached out to customer support and they just assumed that I didn't install it properly. Their only resolution, which they repeated across several occasions, was to update APN and to restart my phone, or to select a different network. All of which I had done prior to contacting and repeated again when they offered these basic resolution. Nothing worked and I switched e-Sim companies. When I requested it after the unhelpful resolution, they just asked to contact me on WhatsApp. Clearly they weren't going to refund. After a useless correspondence with them, I, of course, didn't want to receive anymore, "Please update your APN and restart your phone." Naturally, I ignored their email and gave up. They're clearly the type of company that wears you down until you stop bothering them.
