MUST READ BEFORE BUYING
You must activate this SIM in Malaysia before you fly.

1. Where to activate. Insert and activate the SIM while you are still in Malaysia, before you leave. If you only insert it after you land in China, activation fails and the SIM cannot be used at all.

2. Where it works. China and Macau only. It does not work in Hong Kong or Taiwan.

3. Use it within 30 days. Once activated in Malaysia you must land and start using it in China or Macau within 30 days.

Product FAQ

How do I activate this SIM?

In Malaysia, before you fly. Insert the SIM into slot one, turn on Mobile Data and Data Roaming, then open any website. Leave it in for 5 to 20 minutes until an activation SMS arrives. That SMS confirms activation is complete.

Can I activate it after I land in China?

No. Activation only works while you are outside China. If you wait until you have landed, activation fails and the SIM cannot be used at all. Activate it in Malaysia before you fly.

How long do I have after activating?

30 days. You must land in China or Macau and start using the SIM within 30 days of activating it in Malaysia. If you activate more than 30 days before your trip the SIM expires before you travel, so activate close to your departure.

Does activating start my plan validity?

No. Your plan validity, 30 days or 180 days depending on which you bought, starts only when you land in China or Macau. Each day ends at 12am GMT +8.

Does this SIM work in Hong Kong or Taiwan?

No. This SIM covers China and Macau only. For Hong Kong or Taiwan please use our Hong Kong or Taiwan plans instead.

How good is the network coverage of this SIM card?

In China you are on the China Unicom network, one of the country's largest operators. In Macau you are on the CTM network.

I am travelling to both China and Macau. Do I need to change any settings?

No. Just keep Data Roaming on and it switches over automatically. If it does not pick up a network when you arrive, search manually and connect to China Unicom in China or CTM in Macau.

If I finish my data, can I still surf at a slower speed?

No. Data stops once the 20GB or 24GB allowance has been used. There is no reduced speed afterwards.

Facebook is blocked in China. Can I still access it with this card?

Yes. Popular apps work without a separate VPN. Gemini AI is unavailable, and TikTok is supported on iPhone only.

Can I use WhatsApp to chat and make calls with this card?

Yes, and calling over WhatsApp saves you money. Note that this SIM is data only, so it has no phone number and cannot make normal calls or send SMS.

Is the data inside this card enough for my usage?

An average person uses about 4GB (4000MB) of data over a 15 day period. Usage is likely to be lower when travelling overseas for leisure, as most of the time will be spent sightseeing or participating in outdoor activities.

What are the shipping rates and how long will it take for my purchase to arrive?

Can I use this SIM card in a new phone?

Make sure you make at least 10 to 15 minutes calls and receive calls to unlock the phone so it can be used with overseas SIM cards.

There was no issues at all to use this card in China. I used it when I travelled to Xinjiang in September 2023. The speed and coverage was very fast and stable. It's so simple and convenient to use. The customer service of Hello1010 is very efficient to give assistance and guidance upon any queries.

Fast Compensation

The customer service was advised wrongly and this SIM couldn’t be used in Hong Kong. However, managed to contact the hotline and immediate assistance and solution was given during public holidays. eSIM was pretty simply and connection was stable. The SIM was returned and refunded.
