Our office

Our editorial and business office is based in Shanghai, where the site has operated since 2003. This is a working office rather than a retail storefront, so if you'd like to visit in person, please contact us first to arrange a time.

Common questions about contacting us

How fast will I get a reply?

Most messages get a reply the same day, Monday to Friday, Shanghai time (UTC+8). If you're writing from a very different time zone, your reply may land the next morning your time — that's the time difference, not a delay on our end.

Do you sell SIM cards and eSIMs directly?

No. China Mobile Phones is an independent, informational site. We test, compare, and write about SIM card, eSIM, top-up, and virtual number options for travelers and expats, and some of our recommendations link to partners like Holafly, Ding.com, and eSender. Ordering happens on the partner's site, not ours.

Can you help me choose between a physical SIM and an eSIM before I arrive?

Yes — this is exactly what we're here for. Tell us your device model, travel dates, and whether you need a China number for verification codes (like WeChat or banking), and we'll point you to the guide or comparison that fits.

Can I visit your office in person?

Our office in Shanghai handles editorial and business correspondence rather than walk-in sales, so please contact us before visiting to make sure someone is available to meet you.

I found outdated or incorrect information on the site. How do I report it?

Please send us the page URL and what looks wrong through the form above. China's carrier plans and pricing change often, and reader corrections are one of the main ways we keep pages accurate.

Are you affiliated with China Mobile, China Unicom, or China Telecom?

No. Despite the name, China Mobile Phones is an independent publisher and is not owned by, operated by, or officially affiliated with China Mobile Limited or any other carrier.

Every message is read by Harry Cheng, who has run China Mobile Phones since 2003 and writes the site's SIM, eSIM, and top-up guides.

China Mobile Phones is reader-supported. Some pages link to partners such as Holafly, Ding.com, and eSender, and we may earn a commission if you make a purchase through those links, at no extra cost to you. This never affects how we test or write about a service — see the About Us page for details.
