GOMO is Singtel's no-contract mobile brand in Singapore, built around digital-only sign-up and no lock-in plans. For GOMO subscribers planning a trip to China, roaming is available through the same infrastructure that underpins Singtel's broader international data network, with China supported through both base plan inclusions and standalone add-ons. China presents a specific set of considerations beyond standard roaming: the Great Firewall blocks a wide range of apps and services that Singaporean travellers routinely use, and the local network environment is operated exclusively by state-owned operators. This guide covers how GOMO roaming works in China, what data you get, which networks you connect to, and what to prepare before departure.
GOMO's roaming infrastructure is built on Singtel's network partnerships. In China, the available networks are China Mobile and China Unicom, the two largest state-owned operators. China Telecom is also present as a third option on some roaming configurations. Your device will automatically select whichever partner network provides the strongest signal at your location.
Coverage in China through these partners is extensive in urban areas, including Shanghai, Beijing, Guangzhou, Shenzhen, and Chengdu. In rural areas and less-visited provinces, coverage quality depends on how far you are from major infrastructure. The high-speed rail network and most tourist routes are generally well covered by both China Mobile and China Unicom.
One critical distinction for travel to China: GOMO data roaming works for connectivity, but the internet you access through that connection is filtered by China's national firewall. This affects which apps and services are available, regardless of whether you are on GOMO roaming or a local Chinese SIM.
GOMO's base plans include data for a set of core destinations. China is included in the Asia Infinity plan and higher tiers, typically with a data cap per destination before speed reduction kicks in. Add-ons are available for standalone China access on lower-tier plans.
Always verify current plan inclusions and add-on options in the GOMO app before departure. Plans are updated periodically and the specific data caps may change.
This is the most important practical consideration for Singaporean travellers to China that is separate from the roaming question entirely. China's national firewall (the Great Firewall) blocks Google services (Search, Maps, Gmail, Drive, YouTube), WhatsApp, Facebook, Instagram, X (Twitter), most Western news sites, and many VPN services.
GOMO data roaming gives you mobile connectivity in China, but the internet you access is the filtered Chinese internet. This means:
Set up your GOMO add-on or verify plan inclusion before you fly. The GOMO app allows you to purchase add-ons and check your roaming data balance. Do this on a Singapore Wi-Fi connection before boarding.
Download WeChat and set it up in Singapore. WeChat works in China and is the primary messaging app used locally. Having it set up before arrival means you can communicate immediately without relying on blocked services.
Install a VPN before departure if needed. Research which VPN services currently function in China and install and test them while still in Singapore. Do not attempt to download a VPN app from inside China.
Use Apple Maps or an offline navigation app. Apple Maps sources its China data from local providers and generally works for navigation in China without VPN. Download the specific areas you need offline in advance.
Turn off data roaming until you are ready. After clearing customs at PVG, PEK, or CAN, your GOMO SIM will start searching for a local network. If you have not pre-activated a plan, disable data roaming first to avoid any unintended charges.
For GOMO users on the Asia Infinity plan who travel to China regularly, the built-in 20GB allocation is often sufficient and represents good value. For users on lower-tier plans who need a standalone China add-on for a single trip, the comparison between a GOMO add-on and a travel eSIM comes down to data volume and trip length.
The key advantage of a dedicated travel eSIM for China is that it runs on a separate eSIM profile alongside your GOMO SIM. Your Singapore number stays fully active throughout the trip, receiving calls and OTPs without interruption. For travellers who rely on Singtel-linked banking OTPs or Singapore government service notifications, this dual-SIM configuration is particularly valuable.
A travel eSIM for China also sidesteps the Firewall consideration in the same way GOMO roaming does: both give you connectivity in China, and both are subject to the same content restrictions. The eSIM does not provide a shortcut around the Firewall.
China is a top business and leisure destination for Singaporeans, particularly for trips to Shanghai, Beijing, Guangzhou, and Shenzhen. Business travellers in particular tend to have heavy data needs: navigation across large cities, real-time translation, and communication with local contacts through WeChat all consume data throughout the day.
TurkSIM eSIMs for China connect to China Mobile and China Unicom, giving access to the same national network infrastructure that GOMO roaming uses. The difference for lower-tier GOMO plan users is that a fixed-price eSIM purchased before departure can offer more data for the same cost as the GOMO China add-on, depending on trip length and data needs.
For GOMO users on Asia Infinity who travel to China regularly, the built-in inclusion is often the most convenient option. For everyone else, the TurkSIM eSIM installed before departure on a second eSIM slot ensures your Singapore SIM stays active while you have a dedicated China data connection running in parallel.
Yes. GOMO roaming is available in China through China Mobile and China Unicom. Data availability depends on your GOMO plan: the Asia Infinity plan includes China in the base allocation; lower-tier plans require a standalone add-on.
The Great Firewall blocks Google services (Maps, Search, Gmail, YouTube), WhatsApp, Facebook, Instagram, X (Twitter), and most Western news sites. This applies regardless of whether you are on GOMO roaming, a local Chinese SIM, or any other mobile data connection originating in China.
Open the GOMO app, navigate to the roaming or add-ons section, and select the China data add-on that suits your trip. Purchase before departure while on Singapore Wi-Fi. Check validity period and data limits before buying.
WhatsApp is blocked in China by the national firewall. GOMO roaming gives you connectivity, but WhatsApp cannot function on that connection while you are inside China. Set up WeChat before departure as your primary messaging alternative.
No. A travel eSIM for China connects to the same local networks (China Mobile, China Unicom) and is subject to the same firewall restrictions as any other Chinese mobile data connection. Neither GOMO roaming nor any standard travel eSIM bypasses the Firewall.
Hong Kong and Macau are treated as separate roaming destinations from mainland China. The Great Firewall does not apply in Hong Kong or Macau, and the network partners are different. Check your GOMO plan or the GOMO app for specific Hong Kong and Macau coverage details.
