Free Test 150MB 1Day in USA | Happy China, Hong Kong, Macau 30Days Unlimited Data Sim Card | 15GB of 5G High-Speed Data | Support Google, Whatsapp, Facebook, Instagram and More

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.

I did not read the fine print when I bought a physical sim-card for my iphone 11 pro when traveling to China. It did not work.I was able to reach out the customer service with email, then via whatsapp. Jeff helped me through the process of switching from physical sim card to eSim for my iphone 11. Then the data worked great in China. I have had excellent mobile data service across several major big cities in China. I could access gmail, whatsapp, youtube, etc...If you have a compatible phone, you can go with physical sim-card; if you have a newer iphone, eSIM works great.I highly recommend "Happy China Sim Card" for their customer service and data quality.

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.!!!!!

Fantastic! I was very happy that I bought it before leaving. It worked in both Hong Kong and mainland China as a data connection. Having an Android phone on WiFi behind the Great Firewall hindered me from checking emails and even using Google Translate. When on this SIM, I was able to use the translator and freely communicate with coworkers and shop owners. Thank you!

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.

After working with Jeff via Amazon, he checked, then connects to T-Mobile in US. Auto, might not be true while doing one day check before leaving for China.Connects Automatically upon arriving in China.Out of date: Failed one day test in US, does not connect with four different cell phones, will see if connects when we arrive China.Two phone numbers listed with the product failed to connect WeChat/Whatsapp.

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.

I installed the SIM as soon as I landed in Shanghai, and it started working right away. Throughout my time there, the internet only went down once when I switched back from a Wi-Fi connection. I simply reset the cellular data option, and the SIM worked again without any issues. No complaints.
