How to Change APN Settings on Android
Follow these steps to update your T-Mobile APN settings on any Android device:
- Go to Settings on your Android phone
- Tap Connections (or Network & Internet)
- Tap Mobile networks
- Tap Access Point Names (APN)
- Tap the + (Add) button to create a new APN
- Enter the values from the table above
- Tap the three-dot menu and tap Save
- Select your new APN by tapping the radio button next to it
- Restart your phone
On Samsung Galaxy Devices
On Samsung phones, the path may differ slightly: Settings → Connections → Mobile Networks → Access Point Names. The steps are otherwise the same.
How to Change APN Settings on iPhone
iPhones on T-Mobile typically configure APN settings automatically. However, if you’re on a T-Mobile MVNO or unlocked device, here’s how to check:
- Go to Settings → Cellular → Cellular Data Options
- Tap Cellular Network
- Under Cellular Data, enter:
fast.t-mobile.com - Under MMS, enter MMSC:
http://mms.msg.eng.t-mobile.com/mms/wapenc - Tap Save (top right corner)
Note: Some iPhone models don’t allow APN editing if the phone is carrier-locked to T-Mobile. In that case, T-Mobile automatically provisions the correct settings.
T-Mobile APN Settings for Hotspot & Tethering
If your mobile hotspot isn’t working on T-Mobile, you may need a separate hotspot APN:
| Field | Value |
|---|---|
| Name | T-Mobile Hotspot |
| APN | fast.t-mobile.com |
| APN Type | dun |
| APN Protocol | IPv4/IPv6 |
T-Mobile APN Settings for 5G
T-Mobile’s 5G network uses the same APN settings as 4G LTE (fast.t-mobile.com). The network automatically selects 5G when available. If you’re not getting 5G speeds:
- Ensure your phone supports T-Mobile’s 5G bands (n41, n71, n25, n66)
- Set your network mode to 5G/LTE/3G/2G (Auto) in Settings → Mobile Networks
- Verify you’re in a T-Mobile 5G coverage area
- Check that your plan includes 5G access
Common T-Mobile APN Problems & Fixes
No Internet Connection After APN Change
If you lose internet after updating APN settings, restart your phone first. If the problem persists, go back to APN settings and make sure APN Protocol is set to IPv4/IPv6 and Authentication Type is set to None.
MMS Not Sending or Receiving
For MMS issues, make sure cellular data is enabled (MMS requires data even with Wi-Fi connected). Verify the MMSC address is entered exactly as: http://mms.msg.eng.t-mobile.com/mms/wapenc
APN Settings Are Grayed Out
If APN settings are locked/grayed out, your phone may be carrier-locked. Contact T-Mobile to unlock it, or check if a carrier profile update is available in Settings → General → VPN & Device Management (iOS).

Frequently Asked Questions about T-Mobile APN Settings
What is T-Mobile’s default APN?
T-Mobile’s default APN is fast.t-mobile.com. For MMS, T-Mobile uses the same APN: fast.t-mobile.com. These settings work for all T-Mobile postpaid and prepaid plans on Android and most unlocked phones.
Why is my T-Mobile data slow even with the correct APN?
Slow T-Mobile data despite correct APN settings usually has one of four causes: (1) network congestion in your area, (2) a deprioritized plan tier, (3) the phone doesn’t support T-Mobile’s 5G bands, or (4) a softcap on your current plan. Try checking T-Mobile’s coverage map and confirming your plan’s data speed specs.
Do T-Mobile MVNOs use the same APN settings?
No — T-Mobile MVNOs like Mint Mobile, Metro by T-Mobile, and US Mobile each have their own APN settings, even though they run on T-Mobile’s network. Using T-Mobile’s APN on an MVNO SIM will usually result in data not working at all. Always use the APN from your actual service provider.
What’s the best APN setting for T-Mobile 5G speeds?
For T-Mobile 5G, use fast.t-mobile.com with the APN type set to default,supl,mms,ia. Make sure your phone supports T-Mobile’s mid-band 5G (Band n41) for the best experience. Low-band 5G (Band n71) is widely available but slower.
Still Having Data Issues? You Might Be Overpaying Too.
If your APN settings are correct and data is still spotty, the issue may be with your plan tier. These alternatives run on the same towers — often for far less:
👉 Mint Mobile (from $15/mo on T-Mobile 5G) | US Mobile (from $10/mo) | Tello (from $8/mo)
