Lyca Mobile USA APN Settings (2026): Configure Data and MMS Easily

"Just activated Lyca Mobile in the US, but my data won't load and I can't reach support without service. What APN should I be using?"

Lyca Mobile USA runs on T-Mobile's network as an MVNO with a strong focus on international calling. The Android APN value is straightforward, but the carrier publishes both a primary value (data.lycamobile.com) and a fallback (wholesale) for devices where the primary does not work.

Here is the verified setup for both Android and iPhone, plus what to check when MMS or international calling acts up.

Lyca Mobile Quick Facts

• Lyca Mobile USA is a T-Mobile MVNO with global reach (Lyca operates in 20+ countries). Coverage in the US matches T-Mobile's 4G LTE and 5G footprint.
• The primary Android APN is data.lycamobile.com. If that fails after a reboot, the documented fallback is the shared T-Mobile-network MVNO APN wholesale (with no username or password).
• iPhones running iOS 15 or later usually auto-configure Lyca settings through Apple's carrier-bundles system. Manual entry is rare but documented below.
• Lyca's international calling allowances do not require any APN customization. Minutes count against your plan pool when you dial an international number through the standard phone app.

How to Open APN Settings

International Calling on Lyca

Lyca's international calling allowances are the carrier's headline feature. Most Lyca USA plans include high or unlimited minutes to dozens of countries, with stronger coverage to South Asia, the Middle East, Europe, and parts of Africa than most US carriers offer.

None of this requires APN customization. The minutes count against your plan when you dial an international number through the regular phone app, whether you are on Wi-Fi calling or LTE. International data roaming (using Lyca while abroad) is more limited and typically needs an add-on; check the Lyca account dashboard before traveling.

If a specific international destination is not connecting, the issue is usually plan-level rather than APN-level. Not every plan includes the same destinations, and Lyca occasionally adjusts the list. The APN does not control this.

Common Setup Issues

• After saving the Android APN, reboot the phone. Lyca sometimes does not switch to the new entry until the device re-registers with T-Mobile's network.
• Confirm the APN value is data.lycamobile.com with no extra spaces. The dots and lowercase letters are required.
• If the primary APN does not bring data up, save wholesale as a separate entry and try that. Some Android phones prefer the T-Mobile-shared value over Lyca's specific one.
• If MMS fails, double-check the MMSC and MMS Port. Lyca uses port 8080 (T-Mobile-network standard), not the more common port 80.
• For iPhones, install any pending Carrier Settings update at Settings > General > About.
• If Lyca data appears slow or unreliable, try toggling Bearer between LTE and Unspecified. Some older Android phones need the explicit LTE bearer to register correctly.
• If your phone moved from another carrier, run Reset Network Settings first to clear stale APN entries.

Frequently Asked Questions

What network does Lyca Mobile USA use?

Lyca Mobile USA runs on T-Mobile's network as an MVNO. Coverage and bands match T-Mobile postpaid in nearly all US markets, including 4G LTE and 5G.

Why does Lyca have two APN values (data.lycamobile.com and wholesale)?

data.lycamobile.com is Lyca's specific APN for their slice of T-Mobile's wholesale platform. wholesale is the shared T-Mobile-MVNO value used by Mint Mobile, Ultra Mobile, Tello, and other partners. Either can work on Lyca lines; the carrier publishes both as valid options.

Do I need a different APN for 5G on Lyca Mobile?

No. The same APN handles 4G LTE and 5G on T-Mobile's network. To get 5G specifically, enable 5G in your phone's network mode settings and confirm your phone supports T-Mobile's 5G bands.

Why does Lyca need a username and password when most carriers do not?

Lyca uses PAP authentication with the credentials lmus and plus to identify wholesale traffic on T-Mobile's network. Most T-Mobile-network MVNOs leave authentication blank, but Lyca requires it. Skipping the credentials is the single most common reason a Lyca SIM connects to LTE but cannot pass data.

Are Lyca Mobile USA and Lyca Mobile UK related?

Yes. Lyca Mobile is a global brand with separate national operations in 20+ countries. Each country has its own network partner and APN values. Lyca USA's settings only apply in the US; they will not work on a Lyca SIM from another country.

My APN screen is grayed out on my iPhone. Why?

This usually means the iPhone is carrier-locked to another carrier. Request an unlock from the original carrier first. If the iPhone is unlocked and APN values are still hidden, Lyca's carrier profile is probably handling the configuration in the background.

What does MMS Max Message Size 1048576 mean?

It is the MMS attachment size cap in bytes (exactly 1 MB), the standard across US carriers. Files larger than 1 MB should go through iMessage, RCS, or Wi-Fi-based messaging instead.
