- WangSim Card worked perfectly in ChinaThis sim card worked perfectly in China, fast speed, more than enough data for my trip. And best of all, a +86 phone# for local people to call. Although the majority of people in China use WeChat to communicate now, there're still places and times a real Chinese phone# is needed. Will definitely buy again next time travel to China.

Why did you pick this product vs others?:
I have been using this product 5 times over past 3 years. essentially, every time i visit China, i use this product. I choose this product because its quality is great, and price is reasonable. it's very convenient to use and install.Their customer support is very prompt and helpful. I have recommended to several of my friends. They all like this product. So, highly recommended. - PoetblackPerfect SIM card for China useI was initially annoyed that Amazon had delayed my order (no reason given) so this showed up just two days before I departed for China. Product itself is great, exactly as advertised! They do require an email activation which worried me because of the narrow window I had (You must activate it before leaving for China). They guarantee a 24 hour reply for activation, and mine only took less than 12 hours. Instructions are clear and concise for swapping out the sim and tool is provided. Worked on 5g (or at the least 4g) everywhere we went. Couldn't be happier with purchase!
- LizWorks in China but not for Google pixelI bought two sim cards and installed on an iPhone 11 and a pixel 8 for use in China from March 13 to April 7, 2025. One sim had a label saying that it must be activated by a date that's already passed. I emailed the seller who said that it will still work and to disregard. It did work, a long with the VPN I bought from the seller. There were issues. One phone number was associated with an account that has a outstanding payment due so initially I wasn't able to order Didi or fod delivery. I emailed the seller and they immediately paid off the debt so I was able to use those functions, although I continued to get robo calls and texts for the outstanding balance. The other number initially worked on the first couple of days, then the phone and text functions stopped working (data continued to work.). I notified the seller and they said that it was a common issue with pixel phones. They offered me $5 credit and immediately send me the money by WeChat. I like that it works and how responsive the seller was, but took off a star for these issues. I used their VPN on the iPhone and another VPN (mullvad) on the Google phone. Both VPN worked fine.
- SusGo 3G Solutions!This sim card I got from 3g solutions was a lifesaver for my big trip to China! You all know that from the health code to many other tracking systems in China, you will need a valid Chinese phone number to get around. However, to get a China sim card, you will have to send in a photocopy of your passport to a sim card vendor. So with that, I was trying to find a trustworthy sim card seller online. I chose 3G Solutions because I saw a couple of Expat Bloggers recommended their products. But in the end, what impressed me the most was not their awesome products but their excellent customer service.
To begin with, the trip to China was a big headache for me because the tight quarantine rules and internet control could disrupt my communication with my US office. So I got two VPN routers, my AT&T roaming plan, and the 3G Solutions 20GM data sim card for the trip to ensure my continuous business communication with the US. The first thing I did when I got checked into my tiny quarantine room in Xiamen was to set up my internet connection with two VPN routers, but both failed. Then I tried my iPhone hotspot with my us roaming data and the sim card, but both failed again to show up in my wifi connection. I was like, wow, no wonder they call it the golden shield. I was desperate and frustrated, but I couldn't really do anything since I was locked up. Then I called 3G solution's shanghai office before I went crazy. I was lucky enough to get to talk to Mark. He helped me and tried different wifi settings through WeChat, patiently. Finally, both of my iPhone hotspots worked, and the data plan I got from 3G Solution supported my data connection with the home office for the entire trip to China. I also purchased the wifi rental from 3G Solutions for my backup. But Mark suggested I should cancel this order since I really didn't need it and refunded my money later. With all this, I need to say that Mark and 3Gsoultion truly went above and beyond to help their customers. And I felt very thankful I made the phone call to 3G Solutions and Mark. Otherwise, I had to fly back to the US right after the Xiamen quarantine. I will definitely buy this card again for my next trip to China!
