Struggling for days without a reliable internet connection taught me just how crucial the right China Mobile settings are. My own issues started when I swapped SIM cards in Shanghai, only to find my mobile data would intermittently go dead — even though signal bars were full. After hours digging through forums and trying every fix, I realized how specific APN configuration can be with China Mobile APN. Below is everything I discovered so you don’t have to repeat the struggle!
Quick Summary
- Most stable China Mobile APN config: Use cmnet as APN with default authentication and IPv4/IPv6 protocol.
- Gaming-friendly APN: Separate “cmwap” APN or adding type: default,supl for lower latency.
- Best download/upload profile: Use cmnet, no proxy, Bearer: LTE, for stable uploads/downloads and HD media streaming.
- Carrier-specific issues: VoLTE may be restricted, MMS stuck without “cmwap”, and some devices face “4G” but no internet.
- Rare fixes/workarounds: Toggling ‘data roaming’ or switching APN types like supl,ims — see advanced repair section below.

| Password | <not set> |
| Authentication type | PAP or None |
| APN type | default,supl |
| APN protocol | IPv4/IPv6 |

Best APN for Gaming on China Mobile APN
Online games and real-time apps often demand the lowest latency possible. To reduce lag spikes, these APN configuration tweaks have proven best for China Mobile APN:
| Field | Recommended Value |
|---|---|
| Name | China Mobile Gaming |
| APN | cmwap |
| APN type | default,supl |
| Proxy | 10.0.0.172 |
| Port | 80 |
| APN protocol | IPv4 |
| Bearer | LTE |
Best APN for Downloading & Uploading
For situations like sending large files over WhatsApp, backing up photos, or streaming HD video on China Mobile APN, a streamlined APN setting is recommended. Here is the optimized data config for maximum download and upload:
| Field | Optimized Value |
|---|---|
| Name | China Mobile Data+ |
| APN | cmnet |
| Proxy | <not set> |
| APN type | default,supl,dun |
| APN protocol | IPv4/IPv6 |
| Bearer | LTE |

Troubleshooting Common Issues
- No signal after APN save: Check that MCC and MNC are 460 and 00. Incorrect numeric values will break registration.
- Can’t get 4G, stuck on 3G: Some models require APN type: default,supl,ims and Bearer: LTE. Try enabling VoLTE in device settings.
- MMS stuck or can’t send/receive: Use “cmwap” as APN with proxy and port fields filled in (see Gaming APN above).
- Hotspot won’t work: On some MVNOs, adding dun to APN type is required.
- VoLTE option is grayed out: Possible country/firmware block; try APN type: ims.
- “u/datanuke_91 said enabling ‘roaming’ fixed LTE fallback issues on China Mobile APN.”
Advanced Repair Thinking for China Mobile APN: Creative Workarounds
Reverse Function Mapping on China Mobile
At one point, my SIM on China Mobile registered perfectly — calls worked, texts landed, but absolutely no mobile data for apps like Instagram or YouTube. Turns out, the standard cmnet APN didn’t trigger data routing properly on my imported device.
By mapping what functioned (calls, SMS, basic 3G) vs. what failed (streaming, app downloads), I discovered that switching the APN type from default to default,supl, or even using hipri, forced a different data path. Some users on Reddit also reported success with:
- Creating a duplicate APN but setting APN type: dun,default,hipri to prioritize “high-priority” data.
- On Android, manually selecting the APN in Mobile Networks vs. “Auto” resolved app traffic issues.
Material Echo Principle applied to China Mobile APN SIM behavior
Devices with a Snapdragon X12 modem often synchronize better with China Mobile APN’s infrastructure, possibly due to optimized frequencies and handshakes coded into their SIM/carrier profiles. I found that moving my SIM from a Huawei to a Samsung model instantly improved speeds — a phenomenon echoed by forum users:
“Swapped my SIM from Xiaomi to OnePlus, data speed doubled overnight on same APN. Something’s weird with China Mobile and certain antennas.” — u/skytigerlee
- Try your SIM in multiple phones, especially those with different chipsets or brands.
- Experiment with unofficial firmware or modem updates (at your own risk) if persistent problems continue.
Temporal Stress Testing for China Mobile APN
Some China Mobile plans throttle heavy data users after a set period. In my experience:
- Mobile hotspot worked perfectly for the first 10-12 minutes, but by 15 minutes, speeds dropped dramatically. Continuous streaming for 45 minutes confirmed a pattern of deliberate bandwidth reduction.
- I toggled Airplane mode 20+ times in rural Kunming — only then did 4G+ appear and stabilize.
- Driving from downtown to industrial zones, signal varied, but the APN did not reconnect unless the device was restarted.
This suggests stress-testing your mobile internet fix over several hours — not just a minute or two — to reveal hidden throttling or disconnect patterns.
Hidden Fixes: Rare APN Configurations for China Mobile
The following APN configurations were reported by fringe users and aren’t listed anywhere on China Mobile APN’s official website — but they worked in special cases:
| APN | Settings Highlights | Use Case |
|---|---|---|
| cmnet | APN type: default,supl,ims APN protocol: IPv6 only | iPhone 12 Pro + 5G |
| cmwap | Bearer: HSPA Proxy: 10.0.0.172 Port: 8080 | Older Android MMS fix |
| 3gnet | APN type: default Authentication: None | Rarely works for inbound travelers |
| cmnet | APN type: dun,default Bearer: LTE only | Hotspot fix for portable routers |
| cminternet | APN type: default,supl,xcap APN protocol: IPv4/IPv6 | Some ZTE modem sticks |
| cmhk | APN type: ims Bearer: unspecified | HK roamers needing VoLTE |
| cmnet | APN type: supl,xcap,default APN protocol: IPv6 | In-building 5G in Shenzhen |
| cmwap | APN type: default Proxy: none Port: none | SIM-locked devices with region spoof |
| uninet | APN type: default,supl Authentication: PAP | Transferred numbers from Unicom |
| cmims | APN type: ims Bearer: LTE | VoLTE activation for select devices |
FAQs About China Mobile APN
How to reset China Mobile access point names?
Go to your device’s APN settings, tap ‘Reset to default’, or delete all custom profiles. Restart your phone. The China Mobile Data APN settings will reload from the SIM card, or you can input the standard configurations listed above.
Does China Mobile APN support VoLTE?
Yes, but support depends on your device, plan, and region. Some users get VoLTE only with APN type set to ims or by toggling VoLTE settings after a reboot.
Why isn’t hotspot working even with correct APN?
Some China Mobile SIMs restrict tethering to specific APN types. Add dun to your APN type and ensure your plan officially supports hotspot use. Still stuck? Try another of the obscure APN configurations from above.
Which APN should I use for best speed on China Mobile?
For most, cmnet with default, supl, and dun in APN type offers the fastest and least filtered access for downloads and streaming.
Can I use Hong Kong or international SIMs on China Mobile APN networks?
Roaming usually works with standard APN like cmhk or your home country’s default APN. Some advanced features like VoLTE may not be available, depending on the roaming agreements and device compatibility.
Conclusion
For me, the breakthrough came after switching from a generic “internet” APN to the China Mobile Internet APN settings outlined above — particularly, cmnet with “default,supl,dun” for both hotspot and speed. My advice: test one APN configuration per day, let it run for 8-12 hours, and monitor real performance depending on your city or phone model. Often, just a small tweak in APN type or carrier settings opens up far better stability and speed on China Mobile than the default SIM profile. Good luck!
