If your mobile data suddenly stops working on Excess Telecom, the fastest fix is usually your APN. For most 5G-capable smartphones, Excess Telecom’s own setup guide points to Name: EXCS and APN: ERESELLER (sometimes shown as eRESELLER), plus the AT&T-style MMS details like MMSC: https://mmsc.mobile.att.net, MMS Proxy: proxy.mobile.att.net, and MMS Port: 80. It also lists MCC 310 and MNC 280, with APN Type: default,supl,hipri,fota,mms and APN Protocol: IPv4/IPv6. Those few lines are the difference between a phone that feels “offline” and one that loads maps, messages, and email normally again.
Why Excess Telecom APN settings matter
Think of an APN (Access Point Name) as the “route” your phone uses to reach the internet through your carrier. When that route breaks, everything looks fine on the surface—signal bars may still show—yet apps spin forever, iMessage or MMS fails, and hotspot refuses to share data.
APN issues often show up after a SIM swap, a phone update, a reset, or when a device was previously used on a different carrier. It can also happen when your phone tries to auto-create profiles and picks the wrong one. Excess Telecom even calls out that spelling and exact entry matter, which is true in real life—one wrong character can block data.
A quick reality check before you edit anything
Do these quick checks first, because they solve a surprising number of “APN” problems without touching settings.
Start with a restart. Then toggle Airplane Mode on for 10 seconds and off again. If you recently activated service, confirm your SIM is seated correctly and your phone shows the right network name. If data still fails, move on to the APN.
Also note this: Excess Telecom is a distributor that partners with underlying providers (including IM Telecom and others). That’s normal for MVNO service, and it’s one reason carrier profiles can vary by device and plan.
The official Excess Telecom APN settings you should use
Excess Telecom’s own “Programming Data Settings” section provides a working template for 5G-capable smartphones. Here it is in a clean format you can copy carefully.
| Field | Value (5G-capable smartphones) |
|---|---|
| Name | EXCS |
| APN | ERESELLER (sometimes shown as eRESELLER) |
| Proxy | Not set |
| Port | Not set |
| Username | Not set |
| Password | Not set |
| Server | Not set |
| MMSC | https://mmsc.mobile.att.net |
| MMS Proxy | proxy.mobile.att.net |
| MMS Port | 80 |
| MCC | 310 |
| MNC | 280 |
| Authentication type | None |
| APN Type | default,supl,hipri,fota,mms |
| APN Protocol | IPv4/IPv6 |
| Bearer | Unspecified |
A small detail that trips people up: APN text can appear in different capitalization on different screens. The important part is the spelling. Excess Telecom also notes device categories and labels like ENHANCEDPHONE for 5G smartphones, NXTGENPHONE for LTE devices, and Broadband for data devices. If your phone shows multiple profiles, choosing the one that matches your device type can help.

How to enter Excess Telecom APN settings on Android
Android phones hide APN menus in slightly different places, but the flow is almost always the same.
Open Settings, then go to Network & internet (or Connections on Samsung). Tap Mobile network, then Access Point Names. In that APN screen, create a new APN using the + icon or an Add option. Excess Telecom specifically instructs Android users to add a new APN and “program each field using the settings found in the table,” then save and select the new APN.
Once you save, return to the APN list and tap the circle next to your new “EXCS” profile so it becomes active. Then restart your phone again. That restart step sounds basic, but it forces the phone to re-register data sessions using the correct route.
Samsung, Pixel, Motorola, OnePlus: why your menu looks different
Excess Telecom includes examples for major Android brands (Samsung, Motorola, Google Pixel, LG, OnePlus) because the words on the screen change even though the idea stays the same: find APNs, add a new one, save it, select it.
If your phone blocks editing of certain fields, leave them alone and only enter what you can. Most of the time you only need Name, APN, and the MMS lines.

How to set Excess Telecom APN settings on iPhone
iPhone behavior depends heavily on iOS version and carrier profile support.
iPhone on iOS 17 and newer: it often auto-configures
Excess Telecom notes that on iOS v17 and up, APN settings commonly auto-configure. It also mentions that on newer versions (including iOS 18.5+), a setting called “Use Carrier Settings” is enabled by default, and their troubleshooting steps focus on confirming that it’s turned on for your SIM.
So if you’re on a newer iPhone and data breaks, go to Settings → Cellular → select your SIM, then look for Use Carrier Settings and make sure it’s enabled. Then restart the phone.
iPhone on iOS 16 and older: you may need a profile
For iOS v16 and lower / iPhone X and below, Excess Telecom directs users to connect to Wi-Fi and install a configuration profile through Safari. That profile can push the correct carrier settings when manual APN fields are unavailable.
Apple also explains that some carriers don’t allow manual APN edits, and in those cases you must contact the provider or use a configuration profile if they offer one.
When the “right” APN still doesn’t fix data
If you entered everything exactly and data still fails, don’t assume you did it wrong. A few common situations can block mobile internet even with perfect Excess Telecom APN settings.
Sometimes your phone keeps an older APN active even after you create a new one. Go back into the APN list and confirm your new EXCS profile is selected.
Sometimes the SIM registers voice and SMS but not data until you reset network settings. On Android, you’ll find this under System → Reset options → Reset Wi-Fi, mobile & Bluetooth (wording varies). On iPhone, it’s Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings. After that reset, re-check the APN.
Another common issue is the phone choosing an LTE-only profile when you’re on a 5G-capable device (or vice versa). Excess Telecom’s guide hints at different labels for different device types, so if you see multiple APN choices, try selecting the one that matches your phone category.

Fixing MMS picture messages on Excess Telecom
MMS is picky. Your regular internet browsing may work, but picture messages fail if the MMSC line is missing or the MMS proxy/port is wrong.
Excess Telecom’s table includes all three MMS fields: MMSC, MMS Proxy, and MMS Port 80. If you only filled the APN field and skipped the MMS section, go back and add those lines.
Also keep mobile data turned on while sending MMS. Many phones won’t send MMS over Wi-Fi unless the carrier supports Wi-Fi calling + MMS routing in a specific way.
Hotspot not working: what to check
Hotspot issues can be APN-related, but they can also be plan-related. Start by making sure your main data works first. Then confirm your APN Type includes entries that support broader data behavior. Excess Telecom lists default,supl,hipri,fota,mms, which often helps phones that rely on “hipri” style behavior for tethering.
If hotspot still fails, test with a single device and a simple site like a speed test page or a plain news site. If the connected device shows Wi-Fi but no internet, you may need support to verify hotspot is enabled on your plan.
Keep your setup “clean” so it stays stable
Once you’re working again, keep only what you need.
If you see multiple old APNs from past carriers, remove the unused ones when Android allows it. Too many profiles can cause the phone to “guess” again later, especially after updates.
Avoid “optimizing” values that are already working. The official settings intentionally leave many fields as “Not set.” That’s not missing information. It’s a clean configuration.
When to contact Excess Telecom support
If you’ve done the correct entries, restarted, and reset network settings, and your phone still shows no data or can’t send MMS, it’s time to contact support. Excess Telecom provides phone and chat hours, and their support number is +1 (800) 615-0898.
Before you call, keep your device model, your iOS/Android version, and your SIM details handy. Support can quickly confirm whether your line is fully provisioned for data and whether there’s a known outage affecting activation or routing.
A simple takeaway you can trust
Most “no internet” problems on Excess Telecom come down to one thing: your phone needs the correct route. Use EXCS as the name and ERESELLER / eRESELLER as the APN, keep the MMS lines exactly as shown, and restart after saving. If you’re on a newer iPhone, confirm Use Carrier Settings is enabled. These steps follow Excess Telecom’s own guidance, and they solve the issue for the majority of devices in minutes.
