Happy - China, Macau, Hong Kong 30 Days Unlimited Data Travel Sim (4G 15GB)

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 Amazon, 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.

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.

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.!!!!!

My parents used it when they were traveling to China and Macau. They said it’s perfect! However one of the sim card envelope were already cut open. The other one was still sealed. The speed was fast as well as the connection. It was easy to set up if you read the instructions and follow them.

It is not working to what they said in product description. It said the SIM card will work in Hong Kong and China . Yes. It worked in Hong Kong. But it not working in China. It did not have internet connection at all. I will not use it again.

Connection started right after the sim was turn on and activated. However it did not support RCS, which means no RCS messaging at all. The product description does not mention this issue at all. Be Aware.

On a previous trip to China, I bought a SIM (7 days) in China. Not only was it more expensive and a shorter term, but the Great Firewall of China prevented me from using NordVPN and accessing popular websites like Google and Yahoo. This SIM didn’t even need a VPN to get to those sites. I activated in Hong Kong and it continued to work in Shenzhen, Shanghai, and smaller cities. Highly recommend this if you need a physical SIM in China. I will buy it again.

You will need this when travelling in China in order to access facebook, google, gmail and etc. ChatGPT will not work because it is blocked by ChatGPT.
