We bought two esim cards before our trip to Istanbul. Both worked perfectly. We had a constant connection and the installation was easy.★

I really appreciated the staff's service, and it's close to the British Museum, about a 15-minute walk. It's a great location, incredibly clean, and I tried the breakfast buffet, which was very good, offering the basics but still quite nice.★

Good, fast internet! Installation took 5 seconds using a QR code. Manual installation failed. Worked in both Cyprus and Sweden.★

The signal is excellent. Installation was easy; just follow the instructions. It was ready to use right away after unloading, very convenient. Wi-Fi calling is fantastic; I never miss a call. I'll definitely buy more data when it runs out. Highly recommend! I've only been in London so far, so I'm not sure about the signal outside the city.★
