I'm traveling in Tianjin, China. I thoroughly enjoyed my five-day trip. To wrap things up, I visited Tianjin Ancient Culture Street today. I sampled some of Tianjin's specialties. Tianjin sweets are the best!

Very convenient, 5G is everywhere. We used it in China (Beijing) and Vietnam, and the signal is excellent. They helped with installation and activation.

I purchased this to use in two countries: ** and Vietnam. When I first used it in **, I needed to register with my real name, so I registered using the free Wi-Fi at the airport. I had a little trouble registering, possibly due to signal issues or a problem with my phone, but I successfully completed the registration. After registration, I was able to communicate without any problems and used it comfortably in both ** and Vietnam. I recommend it to anyone traveling to two countries!
