US Mobile is unusual among MVNOs because it lets you pick which underlying network you want. The Warp network rides on Verizon. The Dark Star network rides on AT&T. Light Speed is the T-Mobile-based network option. Each one has its own APN values, and getting the right set into your phone depends on which network you signed up for.
iPhone users have it easier; US Mobile publishes downloadable carrier profiles that handle the entire configuration. Android users typically need to enter values manually. Here is the verified setup for both networks plus what to do on iPhone.
What You Need to Know
- US Mobile lets you pick a network when you sign up: Warp (Verizon), Dark Star (AT&T), or Light Speed (T-Mobile). All three are currently active. The APN values differ between them, so you need to know which network your line is on before configuring.
- iPhone setup is done through a downloadable carrier profile. Visit usmobile.com/apn-download from Safari on your iPhone, pick your network, and let the profile install. No manual APN typing required.
- Android setup requires manual APN entry. The values below are taken from US Mobile's own support documentation.
- After major OS updates, recheck the APN. Updates occasionally reset custom Android APNs back to default.
How to Open APN Settings
Confirm which US Mobile network your account uses before entering values. You can check this in your US Mobile account dashboard or in the activation email. If you switched networks recently, the APN may need to change too.
Android
- 1.Open Settings
- 2.Tap Network & Internet (or Connections on Samsung)
- 3.Tap Mobile Networks, then your US Mobile SIM
- 4.Tap Access Point Names
- 5.Tap the three-dot menu, then New APN
- 6.Enter values from the network-specific list below
- 7.Tap Save, then select the new APN to make it active
- 8.Restart the phone or toggle Airplane Mode for 20 seconds
iPhone and iPad
Skip the manual entry. Open Safari on the iPhone and go to usmobile.com/apn-download. Select iOS as the operating system, choose Warp or Dark Star (whichever matches your line), and tap Download. iOS prompts you to install the configuration profile in Settings. Approve it and reboot. The APN values populate automatically.
Warp Network APN Values (Android)
Use these for accounts on the Warp (Verizon-based) network:
- Name: Verizon 2
- APN:
vzwinternet - Proxy: <Not set>
- Port: <Not set>
- Username: <Not set>
- Password: <Not set>
- Server: <Not set>
- MMSC:
http://mms.vtext.com/servlets/mms - MMS proxy: <Not set>
- MMS port: 80
- MCC: 311
- MNC: 480
- Authentication Type: None
- APN Type:
default,supl,mms - APN Protocol: IPv4/IPv6
- APN Roaming Protocol: IPv4/IPv6
- Bearer: Unspecified
After saving, set this APN as the active one (some phones default to the carrier-bundled APN unless you explicitly select the new entry).
Dark Star Network APN Values (Android)
Use these for accounts on the Dark Star (AT&T-based) network:
- Name: US Mobile Dark Star
- APN:
ereseller(lowercase exactly) - MMSC:
http://mmsc.mobile.att.net - MMS proxy:
proxy.mobile.att.net - MMS port: 80
- MCC: 310
- MNC: 410 (if the entry will not save with 410, try 280)
- Authentication Type: None
- APN Type:
default,supl,mms,ia - APN Protocol: IPv4/IPv6
- APN Roaming Protocol: IPv4/IPv6
For Light Speed (T-Mobile-based, still active alongside Warp and Dark Star), the Android APN is wholesale with MMSC http://wholesale.mmsmvno.com/mms/wapenc, MCC 310, MNC 260. This is the same shared T-Mobile-network MVNO setup used by Mint, Tello, and other partners. Older Light Speed lines on the legacy pwg APN (with MMSC http://pwg.mmsmvno.com/mms/wapenc, same MCC/MNC) still work too if your phone is already configured that way.
iPhone Setup via Carrier Profile
Apple devices on US Mobile use a downloadable carrier profile rather than manual APN entry. The profile carries the correct values for whichever network your account is on (Warp or Dark Star), plus the MMS settings, hotspot config, and LTE/5G fields.
To install:
- 1.Open Safari on the iPhone (it must be Safari; other browsers cannot install configuration profiles)
- 2.Go to usmobile.com/apn-download
- 3.Tap iOS, then tap your network (Warp or Dark Star)
- 4.Tap Download APN and approve any prompts
- 5.Open Settings. A new banner reads Profile Downloaded. Tap it.
- 6.Tap Install in the top-right and enter your passcode
- 7.Reboot the iPhone
If the carrier profile does not appear in Settings after download, search the Settings app for "Profile" and look under VPN and Device Management. If the profile is missing entirely, try a different browser tab in Safari and re-download.
Common Setup Issues
- After saving an Android APN, reboot the phone. The new entry sometimes does not switch to active until the phone re-registers with the network.
- Confirm the network your account is on. The dashboard in your US Mobile account shows whether you are on Warp or Dark Star. Using the wrong APN for your network is the most common reason data fails.
- If you switched networks recently (Warp to Dark Star, for example), the old APN must be deactivated. Save the new APN as a separate entry and select it manually.
- For iPhone, install any pending iOS update and Carrier Settings update before retrying the profile download. Old iOS versions occasionally fail to install US Mobile's profile correctly.
- If MMS works but data does not, double-check the APN type string. The string
default,supl,mmsneeds no spaces. Missingiaon Dark Star can also cause initial-attach failures. - Make sure the phone supports the underlying network's bands. A phone optimized for AT&T may not get good Warp service on Verizon, and vice versa.
- If your account is brand new and data does not work for the first day, give it 24 hours. Initial provisioning can take time, especially after a number port.
Frequently Asked Questions
What is the difference between Warp, Dark Star, and Light Speed?
Warp is US Mobile's branding for service on Verizon's network. Dark Star runs on AT&T's network. Light Speed runs on T-Mobile's network. All three are currently active and US Mobile lets you choose at signup based on which coverage fits your area.
Why does iPhone use a downloaded profile instead of manual APN entry?
The profile carries more than just the APN. It includes hotspot configuration, LTE attach settings, and carrier feature toggles that iOS does not expose for manual editing. Using the profile is faster and more reliable than typing values into Cellular Data Network.
Can I switch networks within US Mobile without changing my SIM?
Sometimes yes, sometimes no. If your SIM is a physical one provisioned for a specific network, you typically need a new SIM to switch. eSIM lines can often switch through the US Mobile dashboard. Check your account before assuming you can move between Warp and Dark Star without a new SIM.
Do I need separate APN values for 5G on US Mobile?
No. The same APN handles 4G LTE and 5G on each network. Your 5G access depends on whether your plan includes it and whether your phone supports the underlying network's 5G bands.
What does Verizon 2 mean in the Android APN name field?
That is just the label US Mobile uses to distinguish their Warp APN entry from a default Verizon entry your phone might already have. It does not affect functionality; you can rename it to anything in the Name field, but the APN value itself must stay vzwinternet.
The Dark Star APN value ereseller sounds like a placeholder. Is it correct?
Yes, ereseller is the real APN value US Mobile publishes for Dark Star. The casing is enforced by AT&T's wholesale platform, so save it in all lowercase. Older guides referenced the value pwg, which was the legacy Light Speed (T-Mobile) APN, not Dark Star. If you have an older account, double-check your network in the US Mobile dashboard before entering APN values.
My MMS Max Message Size on iPhone shows 1048576. Is that right?
Yes, that is the standard 1 MB MMS size limit in bytes used across US carriers. US Mobile follows the same limit on both Warp and Dark Star.
