China Unicom 4G Great China 15 Days Data SIM 5GB FUP

The card was easy to install and worked immediately when I landed in Shanghai Pudong. The Phone has to be unlocked - ensure that this is the case. Easy to pop out the SIM and pop this one. Connected readily and was ready to go after entering the "phone number". I could not check how much was the actual GB that I used, but i was able to use the card for the period i was in China.

Traveling to China and wanted a product that could make my unlocked phone work during my visit. I bought this product based on the reviews. I showed it to my friend who speaks Chinese and she says “this says to use by 8/1/19” Not reading Chinese I did not know that this SIM card is expired. I am a lazy consumer who doesn’t like to spend the effort to send most products back. Shame on the retailer for sending out of date SIM cards and shame on Amazon for taking at face value that the product is what it was advertised to be! Don’t buy this product

After I arrive, just pop it in my cell phone. Work like a champ. The only problem is it does not have any signal within the Chinese Custom.

It's a simple data sim card alternative when traveling to Asia. Installation is easy, simple plug and play. Downloading rate is great, and the limit was way beyond my needs. It's charge is much less than turning on att/Verizon international roaming services, awesome money saver. The only downside is that you can use it to make phone calls. I don't need this anyway. It also comes with an expiration date. Pay attention to that. One of the card I bought for impacted sure to COVID-19.

the delivery is fast but in the package it requires to activate by 6/30, about 10 days after delivery and you can only activate when you at your destination, so basically this is a 2GB for 15 days data card. i give 2 stars for now as it failed to mention the condition. i don't even know how and if it will work when i in china on jul 2 at this time. the main reason i brought this card here is some people said the sim card brought outside china will be allowed to have access to fb, gmail, etc. will review again on whether this is true or not.

I bought it from Amazon and hoped to use it in China during my two-week visit there. The card says 4G network. But it actually shows 3G. I visited Shanghai, Suzhou, and Changchun. I could not do anything with it. I contacted the service center and they told me they would reset the card and made it work. But nothing happened. Not only did it waste my money but also caused significant inconvenience. Don't buy this SIM card.

Highly recommended! This is THE trouble free and foolproof solution if you plan to travel to China and stay connected. The package contains the sim card in a flexible form to fit into three sizes of card slots. Also, it has a pin included for you to pop out your phone's card holder so you have everything. After your landing in China, just turn off your phone, put the card in, turn on the phone and configure the settings to add 3gp, then enable roaming (a detailed instruction is included in the package). Wait for about 5~10 min (ignore the possible original phone plan carrier's 'missing signal' warnings), you'll see the LTE/4G signal. The coverage is amazing even in a remote mountain area. Surfing speed is enough for me to watch YouTube. When the 2GB LTE data is used up, the slower unlimited 2G signal is not good for video streaming but still OK for voice (wechat talk, etc), mobile payments (wechat, alipay) and other stuff. Will definitely buy again!

Son is leaving for China so we bought these SIM cards. They expired almost a year ago. They are unusable!! Do not waste your money!! Buyer beware!!

上海で使ってます。 初日なので、通信速度はストレス感じるほどはありません。 これからどうなるか、わからないので、星を１コ減らす。

Worked Perfectly. when i arrived in china put this Sim in my ipad and worked Just changed the apn to correct apn and restarted ipad and all working

The activation is easy, you can activate in mainland, no need to visit Hong Kong. Just follow the steps inside the booklet and I had data roaming within seconds. The speed is great, no lag streaming videos in mainland China. Can access all Google services and social media sites. Will highly recommend for travelling in China and/or Hong Kong. Be mindful that once the initial 4G data runs out, the speed drops like to sub 3G. The speed is okay for Chinese sites, but a Facebook page will take like 20 seconds to load. It is still a great price for the initial data.

最悪!香港では全く使えないのに、アマゾンのページでは香港で使えると表示されているのは詐欺です。

Worked right away as soon as I landed in HK. Great quality SIM, fast internet and Facebook/WhatsApp/Google worked flawlessly when in China. Thank you!
