Review: Easy to use and works great - Once I arrived in China, I swapped this SIM card with the US SIM card in my phone, and the phone easily found the carrier signal once turned on. I went to three cities on the trip, Beijing, Haikou and Hong Kong, and I encountered no connection issues. In the SIM card instruction or maybe on the product page on desertcart, it mentioned somewhere that real name registration is required in Hong Kong prior to arrival. I tried to do that, but the website asked for a phone number or a data storage card number. Since this is a data only SIM, the number format did not match anything on my phone, so I did not complete the registration process. Nonetheless, the SIM card worked just fine in Hong Kong without registration. All the data rate came at 4G. I could access all my US social media app and news sites, and I could do Facetime with people in US. The only time I ran into a problem was at a local restaurant, where I needed to scan a QR code to access the menu and make the order. I just could not open their site using the QR code. I think the reason was due the default search engine setting in my phone web browser. I am guessing the restaurant was not listed under Google or Bing. If had changed the search engine to a local Chinese one, it may have worked. I did not get to test it because my local friends made the order using their phone. One other word of caution is that this is a data only SIM without a local phone number. Establishing a Chinese mobile payment account (Alipay or We Chat) and making mobile payment will be difficult because real time verification with a local phone number is necessary.
Review: This sim card works great. - The Happy sim works as advertised. I have no problem connected to network once landed in Hong Kong. I also received good customer support from Jeff when I emailed him a question.

### ⭐⭐⭐⭐ It works great if they set it right.
*by L***O on April 20, 2025*

I am back USA now. Before I left for China Guangzhou through Hongkong, I tested it in USA, it didn't work. So I emailed the seller, he told me it will work in Hongkong airport. So when I arrived at Hongkong airport, it didn't work. So I emailed to the seller again, he told me he will reset it. Several hours later when I was in Guanzhou, it worked seamlessly. And when I backed to Hongkong airport several days ago, it still worked great. It means you need ask them make a good setting if you don't want have a problem. By the way, the seller told me that I shouldn't provide any personal information for sim registration. Weird! Online or product guide asked use to scan a code to fill in personal information for registration. So in this case, don't register it.!!!!!
