Xfinity Mobile is Comcast's wireless brand, riding on Verizon's network through a wholesale partnership. Most Xfinity Mobile lines auto-configure the APN on activation, but BYOD Android phones and older devices sometimes need a manual entry. The Xfinity APN has a specific Comcast-branded format that is easy to mistype.
Here is the verified setup, plus the alternative APN values to try if the primary one does not bring data up.
Xfinity Mobile Quick Facts
- Xfinity Mobile is owned by Comcast and runs on Verizon's network. Coverage matches Verizon postpaid in nearly all markets, including 4G LTE and 5G.
- The primary Android APN is COMCAST.RSLR.VZWENTP, the Comcast-specific back-end identifier with Verizon's wholesale platform. Capitalization and the dot separators matter.
- If the COMCAST APN fails after a reboot, fallback values like vzwinternet or internet sometimes work on devices that do not have Xfinity's profile.
- iPhones running iOS 15 or later usually auto-configure Xfinity Mobile through Apple's carrier-bundles system. Manual editing on iPhone is rarely required.
Opening the APN Screen
Try the primary COMCAST APN first. It is the value Xfinity Mobile documents and the one most phones expect. Only fall back to vzwinternet if the primary fails after a clean reboot.
Android
- 1.Open Settings
- 2.Tap Connections (on Samsung) or Network & Internet (most other Android phones)
- 3.Tap Mobile Network, then your Xfinity Mobile SIM if dual-SIM
- 4.Tap Access Point Name
- 5.Tap the + button (or New APN in the three-dot menu)
- 6.Enter the Android values from the list below
- 7.Tap Save, then select the new APN to activate it
- 8.Restart the phone or toggle Airplane Mode for 20 seconds
iPhone and iPad
- 1.Open Settings
- 2.Tap Cellular or Mobile Data
- 3.Tap Cellular Data Network if available
- 4.Enter values from the iPhone list below (rarely needed; iOS auto-configures Xfinity Mobile)

Alternative APN Values
If the primary COMCAST APN does not bring data up after a clean reboot, two alternatives are worth trying as a fallback. Save each as a separate APN rather than editing the first, so you can switch between them while testing.
First alternative: APN value vzwinternet, MCC 311, MNC 480, all other fields same as the primary. This is Verizon's standard generic APN and works on many Xfinity Mobile lines even though it is not the official value.
Second alternative: APN value internet, MCC 311, MNC 480, all other fields the same. This is a fallback that some older Android phones accept when the more specific COMCAST APN fails.
If none of the three work, the issue is usually account-level (activation incomplete, plan suspended, or device not whitelisted) rather than APN-level. Contact Xfinity Mobile support.
Xfinity Connection Fixes
- After saving the Android APN, reboot the phone. Xfinity Mobile sometimes does not switch to the new entry until the device re-registers with Verizon's wholesale platform.
- Confirm the APN value
COMCAST.RSLR.VZWENTPis spelled exactly. The dots are required and the letters are uppercase. Any deviation breaks the entry. - If MMS fails but data works, double-check the MMSC. Xfinity Mobile uses Verizon's standard
http://mms.vtext.com/servlets/mms. - For iPhones, install any pending Carrier Settings update at Settings > General > About. The prompt appears for about 15 seconds.
- If your phone shipped from Verizon postpaid or another Verizon-based MVNO, run Reset Network Settings first to clear the old APN entries.
- If you brought a phone from AT&T or T-Mobile to Xfinity Mobile, confirm it is unlocked and supports Verizon's network bands. Some older Android phones lack the bands Xfinity needs for 5G coverage.
- If activation completed but the APN values do not stick, the device may need to be added to Xfinity's compatible-devices list. Xfinity support can check this and resync the line.
Frequently Asked Questions
Is Xfinity Mobile on Verizon's network?
Yes. Xfinity Mobile is a Comcast-owned MVNO that uses Verizon's network exclusively. Coverage, bands, and 5G access match Verizon postpaid in nearly all markets.
What does COMCAST.RSLR.VZWENTP mean?
COMCAST is the parent brand, RSLR stands for Reseller (the wholesale arrangement Xfinity has with Verizon), and VZWENTP indicates Verizon enterprise/wholesale provisioning. It is the back-end identifier Xfinity uses to route traffic through Verizon's infrastructure.
Why is the APN type just default and not default,supl,mms?
Xfinity Mobile's profile only requires the default type on the primary APN. MMS routing is handled at the carrier-profile level rather than through the APN type field. If MMS fails, the issue is usually the MMSC URL, not the type string. Some BYOD phones may need default,supl,mms for compatibility.
Do I need a different APN for 5G on Xfinity Mobile?
No. The same APN handles 4G LTE and 5G. To get 5G access, enable 5G in network mode settings and confirm your plan includes 5G (most current Xfinity Mobile plans do).
My iPhone APN editor is grayed out. Is that a problem?
No. Verizon-network iPhones intentionally hide or gray out the APN editor because the carrier provisions settings through a profile. Xfinity inherits this behavior. If data is failing, the fix is Reset Network Settings, not manual APN entry.
Can I use vzwinternet instead of COMCAST.RSLR.VZWENTP?
Sometimes yes. vzwinternet is Verizon's generic APN and works on many Xfinity Mobile lines as a fallback. It is not the official value, but it is documented as a workaround when the primary APN fails.
What does MMS Max Message Size 1048576 mean?
It is the MMS attachment size cap in bytes (exactly 1 MB). It is the standard across Verizon-network carriers including Xfinity Mobile. Files larger than 1 MB should go through iMessage or Wi-Fi-based messaging instead.
