International buyers attending the Canton Fair frequently move between exhibition halls, hotels, restaurants, railway stations and supplier factories. A stable mobile-data setup helps keep schedules, supplier contacts and purchasing work accessible throughout the trip.
The most effective setup is usually completed before arrival: verify device compatibility, install an eSIM on Wi-Fi, choose enough data for the full itinerary and retain a backup connection.
What buyers normally need mobile data for
- Communicating with exhibitors and suppliers.
- Opening maps, hotel details and transport information.
- Using translation and note-taking tools.
- Scanning supplier documents and saving quotations.
- Joining calls with overseas colleagues.
- Sharing a hotspot with a laptop during follow-up work.
Do not wait until the exhibition hall
Trade-fair days are busy. Installing a new data plan at the venue wastes time and can be difficult without reliable Wi-Fi. Complete the installation before departure or at the hotel, then follow the activation instructions when the plan is ready to be used.
Choose data according to the working pattern
Buyers who mainly use messaging and navigation can select a smaller plan. Teams that exchange videos, download catalogues and conduct live supplier reviews need more capacity.
- 5GB: suitable for a short visit with light daily usage.
- 10GB: suitable for regular communication and moderate business use.
- 20GB: preferable for long visits, frequent video activity or hotspot use.
Keep the business number available
When the phone supports dual-SIM operation, the original line can remain available for calls or verification messages while the eSIM is selected for mobile data. Before enabling this arrangement, review roaming settings carefully to avoid unintended charges on the original SIM.
Factory visits after the fair
Many buyers travel from Guangzhou to Foshan, Dongguan, Shenzhen, Zhongshan or other manufacturing areas. Do not assume that every supplier office provides usable guest Wi-Fi. Save factory addresses, contact names and transport details in advance, and carry a power bank for long travel days.
Checklist before leaving the hotel
- Confirm the correct mobile-data line is selected.
- Enable data roaming for the eSIM only when required by its instructions.
- Test maps, messaging and hotspot access.
- Save the supplier address in both English and Chinese where available.
- Keep the QR code and manual installation information secure.
