What is the validation period of the SIM card? How can I extend it ?

Validation period is 90 days after first use. Validation period can be extended on https://www.china-mobile-phones.com/4g-topup.html by purchasing “Keep your number” service.

Can I use my China Unicom SIM card outside China?

Yes, the international roaming feature is enabled on your China Unicom SIM card; however, international roaming tariff is rather expensive. We do not recommend you to use it as it will impact the balance of the service package on your SIM card, and even suspend your SIM card due to lower balance.

Can it be delivered to outside China, such as Singapore, India, Malaysia?

Yes, we can. 

Free delivery in Australia and New Zealand via the order form on www.china-mobile-phones.com/China-4g-lte-sim.html 

Delivery to the rest world is via the order form on China 4G SIM Card. 

How long will it take to deliver to mainland China?

It takes about 2-3 business days to deliver the SIM card to most of the major cities in mainland China.

How can I track the delivery details?

The tracking number and your new China Unicom phone number will be provided once it has been sent out. 

Can you change the data package into balance because my phone cannot use data in China?

Unfortunately, we cannot make such change due to operator’s policy during the first 90 days. If you want to change the service package, you can do so after 90 days if you purchased the Keep your number service.

How to check my balance and data?

Just send text "101" to 10010 for airtime balance or send text "2082" to 10010 for data balance. These texts are free of charge.

Why I cannot get information although I have top up successfully and sent message”2082” to 10010?

Most of the time, this is due to system response timeout. Please avoid top-up in the beginning of each month, because there are many customers top up during that time, operator’s system has delays to respond. You can check it later.

Why I cannot use the data although I have refill 100RMB?

Balance cannot change into data directly, you have to refill data on www.china-mobile-phones.com/4g-topup.html, but if your SIM card was not bought from us, it will not allow you to refill data directly.

How do I make a call when traveling in mainland China?

• Call a Chinese mobile number: dial the 11 digit mobile number directly; Chinese mobile number all starts with 13../15../17../18… For example, call number 15680912345 directly.
