Do you have your phone service through a mobile virtual network operator (MVNO)? If so, your carrier may not tell you what network they actually use to provide you with service. But there is an easy way to figure that out, and it comes from looking at your device’s APN settings.
APN settings consist of several fields that define how your device connects to the internet and other network services. Key fields in APN settings that were going to look at include:
- Name: The name of the APN configuration.
- APN: The actual APN (Access Point Name) string.
- MMSC: The Multimedia Messaging Service Center URL.
- MNC: Mobile Network Code.
Sometimes your device’s APN name will tell you what carrier you are using. Look at the screenshot below for the MVNO carrier MobileX. The name of the APN says Verizon, which tells us that MobileX is using Verizon as its carrier network partner.
Many times though, it won’t be as simple as looking at the name. The name will usually just be the name of the carrier that is providing you with service. But you can also just look at your “APN” for a hint. In the case above, we see VZWENTP in the APN. VZW is shorthand for Verizon. Below is a list of APNs you may see and the carrier they are associated with.
- AT&T associated APNs – ereseller, reseller, ndo, Endo, NXTGENPHONE, ENHANCEDPHONE, NRPHONE
- DISH network APN – wireless.dish.com (may also indicate T-Mobile for DISH)
- T-Mobile – wholesale, fast.t-mobile.com, pwg
- Verizon – vzwinternet, Y.VZWENTP (where Y can represent combination of several letters)
Another place you can look to see the carrier is at the MMSC APN setting. Here are some common MMSC setting for each carrier.

- T-Mobile – http://mms.msg.eng.t-mobile.com/mms/wapenc, http://pwg.mmsmvno.com/mms/wapenc, http://wholesale.mmsmvno.com/mms/wapenc

As you can see, identifying your phone’s carrier by examining the APN settings is a straightforward process that can provide valuable information, especially if you are using a device with an unknown SIM card or if you are troubleshooting connectivity issues. By accessing the APN settings and comparing them with known carrier configurations provided on mobileapns.com, you can determine which carrier your device is using and ensure that the settings are correct for optimal performance.
