A SIM card with an excellent combination of data, voice and text!
When I started looking for a sim card for my upcoming trip, I skipped the ones with lot of reviews and picked this one that had no review yet. Here is why: 1. I like the combination of data, voice and text. With the current quarantine requirement in place, having a large data plan will be very helpful from handling business tasks to surfing internet to kill time. Don't expect too much from the wifi at hotel as it will be shared by many customers in quarantine. 2. It came with very clear instructions of activation and use. Once I provided the information as instructed, I received the confirmation of activation by email in 24 hours. Yes, I was asked to provide a copy of passport. In China, it has been implemented for years for a user to have a phone number associated with real name/identity. Be aware before you buy and take it easy when you see this part of the instruction. 3. The seller also provides a web site to extend, or buy more data or voice time if needed. I consider this is a nice option for short-term users who may need the sim card/phone number for more than 30 days. 4. When I was still searching, I believe that I used their sim card for a trip back in 2019 after comparing the names of the sellers and the product descriptions. The name of the seller changed slightly (with a space added), and the product descriptions are presented in a similar way. I had positive experience back then, so I decided to give it a try even if it didn’t have any review yet. After I went through the activation, it turns out that I’m dealing with the same team. Overall, this is a perfect and reliable solution with great flexibility for people who are going to spend a short trip in China.

Must have going to China
Worked flawlessly since touch down. Enough for a month on the road within China. Essential to have a local mumber to get public wifi, taxi, rental, food delivery and shopping. Make sure you follow the activation instruction before your trip

Perfect SIM card for China use
I 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!

Used for Glocalme and added on VPN service
I got this sim for my Glocalme WiFi hotspot because Glocalme’s cloud sim packages are too expensive for a trip to China. It worked without any problems although you need to wait quite a while for the cell phone network to pick up on the hotspot. To avoid the long start up delay I just leave the hotspot on 24/7. My Astrill VPN didn’t work in China so although I had WiFi it really wasn’t that functional. I reached out to 3Gsolutions over email and they responded to me quickly and pointed me to their VPN service, 60 days for $24. The web activation was simple and I was able to pay using PayPal. Now connecting to my Glocalme hotspot and running VPN on my iPhone works seamlessly. Highly recommend their Sim and VPN for any foreigners traveling to China. One tip, download the VPN app “Outline App” before you come to China because the App Store won’t work over WiFi. I had to do data roaming on my phone to download the app while I was China and pay ATT roaming data at $2 per MB. The outline app is 7 MB so $14 Not cool but price to pay to not need to data roam for the rest of the trip.

Worked perfectly from arrival in China on
Update - this should now be a one star review, but Amazon didn't let me change it yesterday. Let's see what happens this time. I ordered another SIM card, packed it up and brought it to China. When I opened the package it was empty - just a piece of plastic where the SIM card should be. Total ripoff, and the company did not respond to my emails. I had been advised that there was no way to buy a SIM card in the airport during quarantine. That was true. This SIM card worked perfectly, and I was able to use WeChat, MeiTuan, etc. and initiate calls right away. I also had a number to give to all my friends. It was easy to renew, and good value for money. The company is also helpful and responsive. Update: And the number has worked perfect again, now that I'm back in China - was outside the country from Jan to Jun 2023. The company was very helpful in enabling me to pause and then restart the service. This really has been the easiest China SIM card experience I've had in many years.

Recibí un paquetito donde se ven adaptadores de SIM card y pensé que no me dieron la SIM CARD con datos ya estaba cancelando el pedido, pero busque bien y la SIM está como escondida en el paquetito debajo de una calcamonia con instrucciones de activación. A ver qué tal ya que este allá en China, les estaré informando.

This is a scam- the SIM card I bought was still in another person’s name , as a result I was not able to connect to my Alipay and WeChat, thus was without money for 3 days in a foreign country!I went to China Unicom to make inquiries and was told that 3 G bought the recycled SIM card in bulk ( thus still have previous person detail), thus I couldn’t connect my Alipay . They said I have been scammed!

Fue de bastante ayuda en mi viaje por China. Les recomiendo Comprar con ellos mismos la VPN, ya que la compré por separado de otra marca y prácticamente no funcionó. Una vez que compré con ellos su VPN, la comunicación fue excelente (Incluso en los pueblos alejados de las ciudades). Muchas Gracias.
