## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Item is as described - I highly recommend it!
  

*by E***4 on Reviewed in the United States on November 2, 2018*

I bought this sim card in anticipation of my visit to China. It works very well as I'm in China right now and can access the internet to visit Facebook, Google, YouTube, etc. I was able to use Google maps without a problem. I tested this in Beijing, Guangzhou and in local towns of Guangdong. I do suggest you get multiple sim cards if you plan to stay in China for over 2 weeks and have minimal access to internet. These cards are cheaper if you buy them in Hong Kong as well.Regardless, I highly recommend this product. You should screen capture the APN information too before you go on your trip in case you use an android phone and the settings don't work automatically. The card worked instantly once I inserted the card into the phone.

    Very Happy with this SIM! Worked great in China!
  

*by C***R on Reviewed in the United States on November 28, 2019*

I just back from a 10 day tour through China and purchased this SIM card in advance with hopeful optimism. Suffice it to say I was very impressed. I was supposedly getting 4G service on my unlocked Samsung S8 and could access all my messaging, Google, and social media without a vpn. I even tethered several devices without a problem, although that slowed things down quite a bit. I wil be recommending this to my brother who will be traveling to China in another couple of months.
