OnePool's unique advantages:

Currently, OnePool's shared data feature is specifically optimized for usage between the United States and China—this is our core signature service. For other countries and regions, we offer standard international roaming services. Please check our website or contact customer service for specific rates and coverage. We're continuously expanding our service coverage and may add shared data support for more countries in the future.

No need to enable international roaming or purchase any roaming packages! This is what makes OnePool special. When you arrive in China, simply make sure:

No need for a new SIM card! If you're already a Panda Mobile customer, the OnePool feature automatically applies to your existing plan using your current SIM card. Just make sure your plan has been upgraded to a OnePool-enabled version.

In China, your phone connects to our partner carrier networks. Your phone screen will display the local carrier name, but you're still using your Panda Mobile OnePool plan at no extra cost. The system automatically selects the network with the best signal to serve you.

You do not need a VPN to use OnePool data in China. OnePool provides standard local network connectivity, allowing you to access websites and apps that are available within China.

As a Panda Mobile user, we recommend that you comply with local laws and regulations when using network services. If you have specific internet usage needs, please research relevant policies in advance to ensure your usage complies with local regulations.

In China, OnePool provides 4G/5G high-speed network access, with specific speeds depending on network coverage in your area. In most urban areas, you'll enjoy the same high-speed network experience as local users. We don't impose additional speed restrictions on data used in China—your experience is essentially the same as in the US.

Panda Mobile offers various data plan options, from basic data to unlimited data plans. The specific data allowance depends on your chosen plan type. You can:

Regardless of which plan you choose, your data can be shared between the US and China.

If you use up your plan's high-speed 5G data allowance, speeds will be reduced, but you can still continue to use the internet. We'll notify you when you reach 80% and 100% of your data.

At that point, you can choose to:

Yes, you can continue to use it. OnePool is a shared data pool, so if you've used up your high-speed data in the US, you'll maintain the same network status when you return to China. Conversely, if you use up your data in China, the same applies when you return to the US. We recommend choosing a plan with appropriate data based on your binational usage frequency.

No! This is the core value of OnePool. Using OnePool service between the US and China generates absolutely no additional roaming charges. Your monthly plan fee already includes usage rights in both countries. Regardless of which country you're in, you're using the same data pool and the same plan—billing is clear and transparent with no hidden fees.

If you're an existing Panda Mobile customer, the OnePool feature may have already been automatically upgraded to your plan. We recommend:

No! OnePool feature doesn't require changing your SIM card or eSIM. Whether you're:

It won't affect your plan's benefits. No matter how long you stay in China, your plan will continue to renew and function normally. However, please note that Panda Mobile is a US carrier service based on T-Mobile's network. If you plan to live in China long-term (more than 3 months), we recommend contacting our customer service team to discuss the best solution for your situation. We'll provide optimal recommendations based on your actual usage patterns.
