Can I Use a Mobile Hotspot with a China eSIM?

Yes, you can use a mobile hotspot and tether other devices when using a ChinaRoam eSIM in mainland China. All our plans support personal hotspot functionality, allowing you to share your uncensored 5G data connection with laptops, tablets, or other smartphones.

Traveling through mainland China often presents a unique set of connectivity challenges, especially for those who need to stay productive or keep in touch with family back home. Whether you are navigating the bustling streets of Shanghai or exploring the ancient history in a Nanjing travel guide, having a reliable way to connect your secondary devices is essential. Many travelers find that relying solely on public Wi-Fi is frustrating due to the Great Firewall, which blocks essential services like Google, Instagram, and WhatsApp. By using a travel eSIM with hotspot capabilities, you create your own secure, uncensored bubble of internet access.

Why Tethering is Essential for China Travel

For international travelers, the ability to tether is more than just a convenience; it is a necessity for several reasons:

1. Bypassing the Great Firewall: Local Chinese SIM cards and public Wi-Fi networks are subject to strict internet censorship. When you use a ChinaRoam eSIM, your data is routed through international servers. This means you can access your Gmail, scroll through Instagram, or use Slack on your laptop without needing a separate VPN. If you see plans, you'll find that this uncensored access is built-in.
2. Security: Public Wi-Fi in airports, hotels, and cafes can be a security risk. Tethering to your own encrypted eSIM connection is significantly safer for banking or accessing work emails.
3. Cost Efficiency: Instead of buying multiple SIM cards for every device, you can buy one high-capacity eSIM and share the data across your phone and laptop.
4. Work on the Go: If you are a digital nomad or a business traveler, you likely need a stable connection for your laptop. A 5G hotspot from your phone provides a much faster and more reliable experience than most hotel Wi-Fi networks in China.

ChinaRoam vs. UK Carrier Roaming

For British travelers, the temptation to simply turn on roaming with EE, Vodafone, or O2 is high. However, the costs are often prohibitive. UK carriers frequently charge between £5 and £7 per day for a very limited amount of data, or worse, they charge per megabyte. Furthermore, roaming speeds are often throttled, making tethering a painful experience.

Feature	UK Carrier Roaming (EE, O2, Vodafone)	ChinaRoam eSIM
Cost	High daily fees or per-MB charges	Affordable fixed-price plans
Data Limits	Often capped at 500MB or 2GB daily	Up to 50GB or high-speed daily passes
Hotspot Support	Often restricted or throttled	Fully supported at high speeds
Censorship	Usually uncensored (but slow)	Uncensored 5G access
Network	Varies, often stuck on 4G	5G on China Mobile, Unicom, Telecom

By choosing to see plans specifically designed for China, you ensure that your hotspot remains functional and cost-effective throughout your trip.

Network Coverage: 5G in Cities and Rural Areas

China has the world’s most extensive 5G infrastructure. ChinaRoam plans connect to the three major state-owned carriers: China Mobile, China Unicom, and China Telecom.

• China Mobile: This is the largest carrier with the most extensive coverage in rural areas. If you are heading to the mountains or smaller towns, China Mobile provides the most consistent signal.
• China Unicom: Known for having excellent compatibility with international phone hardware, Unicom offers very high speeds in major metropolitan areas like Beijing, Shanghai, and Guangzhou.
• China Telecom: Provides a robust alternative with strong 5G penetration in southern China.

In major cities, you can expect 5G speeds that rival or exceed home fiber connections. This makes tethering your laptop for video calls or large file uploads entirely feasible. In more remote regions, the network may drop to 4G/LTE, which is still sufficient for basic browsing and messaging. Before you buy, make sure to check your device compatibility to ensure your phone supports the 5G bands used in China.

How to Enable Hotspot on Your eSIM

Setting up a hotspot is straightforward, but it requires that your eSIM is correctly installed and that "Data Roaming" is switched on. Since these are travel eSIMs, they use roaming technology to route your data outside the Great Firewall.

On iPhone (iOS):

1. Go to Settings > Cellular (or Mobile Data).
2. Ensure your ChinaRoam eSIM is selected as the Cellular Data line.
3. Toggle Data Roaming to ON.
4. Go back to the main Settings menu and select Personal Hotspot.
5. Toggle Allow Others to Join to ON.
6. Set a strong password and connect your laptop to the Wi-Fi network named after your iPhone.

On Android:

1. Go to Settings > Network & Internet > SIMs.
2. Select your ChinaRoam eSIM and ensure Roaming is ON.
3. Go back to Network & Internet and select Hotspot & Tethering.
4. Tap on Wi-Fi Hotspot and toggle it ON.
5. Configure your Hotspot name and password.

If the hotspot does not work immediately, you may need to check the APN (Access Point Name) settings. While most phones configure this automatically, you can find the specific details in our installation guide.

Choosing the Right Data Plan for Tethering

Tethering consumes data faster than using a phone alone. Background processes on laptops, such as Windows Updates, iCloud syncing, or OneDrive backups, can drain a small data plan in minutes.

ChinaRoam offers a variety of plans to suit different tethering needs:

• Light Users: If you only need to check emails on a tablet, the 3GB or 5GB 30-day plans are sufficient.
• Power Users: For those working remotely, the 20GB or 50GB plans are recommended.
• Short Trips: If you are doing a Shenzhen day trip guide from Hong Kong, a 1GB or 2GB daily pass might be the most efficient choice.

Our plans range from fixed allocations (e.g., 10GB/30 days) to daily passes that provide a high-speed allowance (like 1GB or 2GB per day) followed by unlimited data at reduced speeds (384-512 Kbps). Remember that these are data-only plans; they do not come with a local Chinese phone number. However, you can use WhatsApp, Skype, or FaceTime for calls over the data connection without any issues.

Arrival Logistics: Getting Online at the Airport

When you land at major hubs like Beijing Capital (PEK) or Shanghai Pudong (PVG), the first thing you'll want is a connection. While these airports offer free Wi-Fi, they usually require a Chinese phone number to receive an SMS code for access. This is a major hurdle for international travelers.

With a ChinaRoam eSIM, you can activate your data as soon as the plane touches the tarmac. You won't need to hunt for a SIM card kiosk or struggle with airport Wi-Fi. Once your phone is connected, you can immediately turn on your hotspot to give your travel companions a connection or to look up directions to your hotel on a larger tablet screen.

Troubleshooting Common Hotspot Issues

If you find that your phone has internet but your tethered laptop does not, check the following:

1. Data Roaming: Ensure Data Roaming is enabled for the eSIM. Without this, the data won't flow, and the hotspot will have no internet source.
2. APN Settings: Some Android devices require the APN to be manually entered into the "Hotspot APN" section as well as the main cellular section.
3. VPN Interference: If you have a third-party VPN active on your phone, it may interfere with the hotspot's ability to share the connection. Since ChinaRoam is already uncensored, you should turn off any extra VPNs.
4. Maximum Connections: Some phones limit the number of devices that can connect to a hotspot simultaneously (usually 5-10).

The bottom line

Using a mobile hotspot with a China eSIM is the most effective way for British and international travelers to maintain a high-speed, uncensored internet connection across all their devices. By bypassing the Great Firewall and avoiding the exorbitant roaming charges of home carriers, you can stay productive and connected throughout mainland China, Hong Kong, and Macau. Whether you're using 5G to upload photos or to work from a cafe, the flexibility of tethering ensures you are never disconnected.
