Many website owners find that their site loads fine on China Telecom and China Unicom, but fails completely on China Mobile. In the industry, this is commonly referred to as "China Mobile blocking." It's not a network issue at its core, but rather a regional or policy-based restriction implemented by China Mobile's network side.

This article uses real-world case studies to explain why China Mobile blocks websites, which types of businesses are most susceptible, and the currently effective solutions for bypassing these restrictions and restoring access.

1. What is "Bypassing China Mobile"?

In many CDN discussion groups and technical circles, "Bypassing China Mobile" refers to access issues, blocking, or restrictions on the China Mobile network.

Typical symptoms:

• Website fails to open on China Mobile 4G/5G ❌
• Access failure on China Mobile broadband ❌
• Completely normal on China Telecom and China Unicom ✅

So you'll often hear people say: "My site is blocked by China Mobile."

Simply put: 👉 Your site has been caught by China Mobile's network policy.

2. Why Does China Mobile Block Websites?

Without getting too technical, the simple truth is: Carriers have their own risk control systems.

Common triggers 👇

1. Sensitive Content or Business Type

This includes but is not limited to: gray-area businesses, download sites, streaming/resource sites, unlicensed (non-ICP) sites (especially those accessed from within China).

👉 China Mobile's policies tend to be "stricter."

2. IP Address Has a Contaminated History

Even if your site is currently legitimate, if you previously used a "problematic IP," or if there were policy-violating sites on the same IP,

👉 Your site may be blocked by association.

3. High-Defense CDN Nodes Are Flagged

Many high-defense CDN IPs: have previously handled attack traffic and are therefore closely monitored by carriers.

The result: Entire IP ranges get restricted on China Mobile.

4. Abnormal Traffic Patterns (Suspected as Attack Source)

For example: sudden high concurrency, unusual request patterns.

China Mobile may then determine: 👉 Suspected attack or problematic site.

5. DNS Poisoning / Hijacking

Another scenario: 👉 Users on China Mobile's network resolve to the wrong IP address.

Manifestations: site fails to open, unexpected redirects.

3. Typical Symptoms of "China Mobile Blocking"

You can quickly identify it: Only China Mobile can't open the site, access from China Mobile varies by region, sometimes works and sometimes doesn't, ping fails / TCP connection fails.

👉 The essence is: Regional network-level restriction.

4. Why Many Standard CDNs Are More Easily Blocked

To be frank about industry realities: High-defense CDNs are particularly susceptible.

The reasons are simple.

1. Heavy IP Address Reuse

A single IP may host dozens or even hundreds of websites.

If just one of them has issues, all are affected.

2. History of Attack Traffic

High-defense CDN nodes are, by nature, "magnets for attack traffic."

This makes them a focal point for carrier monitoring.

3. Abnormal Cross-Border Origin Paths

Many solutions route traffic: overseas → mainland China.

This type of path can more easily trigger risk controls on China Mobile.

5. How to Confirm Your Website Is Blocked by China Mobile

Here are some practical methods 👇

✔ Test Directly on China Mobile's Network

• Access via mobile data
• Do not use Wi-Fi

✔ Test from Multiple Regions

Check whether certain provinces are completely unable to access the site.

✔ Packet Capture / Connection Testing

Common observations:

• TCP handshake failure
• Connection reset (RST)

6. Core Strategies to Solve "China Mobile Blocking"

There's no "one-click fix" for this issue. The essence is: Bypass or evade carrier policies.

Approach 1: Switch to a Clean IP (Short-Term Solution)

• Change IP range
• Change nodes

Drawback: High likelihood of being blocked again quickly.

Approach 2: Carrier-Specific Traffic Routing

Route:

• China Mobile users → dedicated pathway
• China Telecom/China Unicom users → other pathways

Approach 3: Multi-Layer Relay (Advanced Method)

Utilize:

• Relay nodes
• Dynamic routing

To make traffic paths appear "more natural."

Approach 4 (Recommended): Use an Anti-Blocking CDN Solution

This is currently the most stable approach 👇

Specifically optimized for carrier policies:

• Clean IP pool
• Dynamic path switching
• Anti-blocking routing strategies
• Avoidance of sensitive paths

7. Why More People Are Turning to Anti-Blocking CDNs

Simply put: Standard CDNs cannot solve carrier-level blocking issues.

Solutions like CDN07 aren't just about acceleration; they are fundamentally "accessibility-first" network designs.

Key advantages:

• Specifically optimized for China Mobile blocking
• Dynamic switching of egress points and nodes
• Avoids prolonged exposure of a single IP
• Supports global user access
• No restrictions on business type

8. Direct Solution

If you've confirmed that your site is blocked, stop trial and error and go with a proven solution.

Solution: Easily Handle Domain/IP Blocking Issues

The core of this solution is:

• Avoid detection by carriers
• Automatically bypass blocked paths
• Improve accessibility on China Mobile's network

"China Mobile blocking" isn't a network线路 issue—it means your site is on the carrier's radar.

No matter how much you optimize bandwidth, nodes, or latency,

it won't help. The only truly effective approach is: make your traffic "look normal."

FAQ

1. Is China Mobile blocking permanent?
Not necessarily, but many instances involve long-term policy enforcement.

2. Why do China Telecom and China Unicom work fine?
Because the three carriers have different policies.

3. Would using a server in China help?
Not necessarily; it could actually make your site subject to stricter regulation.

4. Does HTTPS help?
It can help, but it doesn't completely solve the problem.

5. Can I file an appeal?
This is generally very difficult.

6. Can Cloudflare solve this?
It works in some cases, but it's not consistently reliable.

7. Why does it sometimes open?
Policies are dynamic and can change over time.

8. What's the most stable solution?
An anti-blocking CDN (such as CDN07).
