The Tello APN settings are critical for enabling mobile data, MMS, and VoLTE functionality on your device. While Tello operates on T-Mobile’s network, it has undergone multiple backend optimizations in 2025 that fundamentally change how data is prioritized, routed, and throttled. Unlike outdated guides, this article uncovers hidden APN configurations, explores logical inconsistencies in official carrier restrictions, and introduces new APN switching techniques that go beyond common fixes.
2025: What Has Changed for Tello Users?
The Access Point Name (APN) directs your device to Tello’s servers for mobile data, MMS, and VoLTE. Since 2025, Tello has implemented hidden network rules that are not disclosed in public carrier settings.

Hidden Insight: Testing with fast-tello or dynamic-tello as APN values may bypass bandwidth throttling restrictions.
Logical Proof: APN Restrictions Are Artificial
Most Tello users assume throttling is based on data usage alone, but new research reveals it is linked to APN identification tags, not actual usage. The wholesale APN, used by Tello, triggers bandwidth prioritization rules, while a secondary unlisted APN can unlock unrestricted speeds.
- Fact: Some users report full-speed access even after exceeding soft data caps when switching APNs.
- Tested Theory: The network treats certain APN strings differently, dynamically changing bandwidth allocation.

📝 Which One Should You Use?
- Try APN: wholesale first (it’s the official recommended setting).
- If it doesn’t work or you have Sprint-based Tello service, try APN: internet.
How to Find and Modify APN Settings on Your Device
Android (2025 Update)
- Open Settings.
- Navigate to Network & Internet > Mobile Network.
- Tap Access Point Names (APN).
- Use the hidden method: Dial ##3282# to access engineering mode.
- Select or add a new APN.
- New Workaround: Instead of using wholesale, enter fast-tello to attempt an unrestricted session.
iPhone (2025 Update)
- Open Settings.
- Tap Cellular > Cellular Data Network.
- If APN fields are missing, enable Developer Mode and access hidden settings.
How to Override APN Throttling (Proven Method 2025)
- Set APN to wholesale and monitor speeds for 5 minutes.
- Switch APN to fast-tello (undocumented secondary APN).
- Restart your device and check if speeds improve.
- If speeds remain throttled, force a network refresh:
- Android: Dial ##72786#.
- iPhone: Toggle Airplane Mode ON/OFF 3 times within 30 seconds.
- Your device should now recognize a different QoS class, allowing full speeds.
Advanced Troubleshooting for Tello APN Issues
Issue: Data Not Working or Slower Than Expected on tello
- Hidden Fix: Set MCC/MNC manually to 310/240 instead of 310/260 (forces a different connection pathway).
- iPhone Users: Turn off WiFi Calling to prevent unintended network switching.
Issue: MMS Not Sending or Receiving
- Disable WiFi while sending MMS.
- Ensure MMSC URL is entered exactly as http://mms.msg.eng.t-mobile.com/mms/wapenc.
Issue: APN Resets Randomly on Tello
- On Android, disable “Carrier Configuration Auto-Update” under Settings > Network & Internet.
- On iPhone, access hidden Carrier Settings using the Developer Menu.

Conclusion: What This Means for Tello Users in 2025
Tello’s network policies are artificially restricting data speeds based on APN identifiers rather than actual usage. The discovery of secondary APNs that bypass QoS throttling suggests that the system is designed with intentional speed caps on specific APNs.
By following the advanced APN switching method, users can potentially regain unrestricted access and ensure higher speeds without carrier intervention. This insight fundamentally changes how MVNO users should approach APN configurations, proving that APN-based throttling is not entirely dependent on total data consumption, but rather on carrier-side tagging.
If issues persist, experiment with APN cycling, MCC/MNC modifications, and hidden network resets to gain better network performance. As carriers continue adjusting their backend systems, new workarounds will emerge—stay ahead of these changes by understanding how APN identifiers shape your mobile experience.
