During this trip through Europe and Africa, I visited the Egyptian pyramids, the Balat in Turkey, several grand mosques, and numerous tourist attractions in Hamburg, Germany. The signal was consistently stable and fast throughout the trip. The only drawback was that I had to switch service providers frequently in Germany, resulting in occasional signal drops.
