Use the right APN for Boost Mobile — depends on your SIM type
This guide covers the Boost Mobile profile for the United States. Boost Mobile is in transition: new SIMs run on the T-Mobile network, while older AT&T-based SIMs use different APN values.
The APN you need depends on which Boost Mobile SIM you have. T-Mobile network SIMs use Boost_Mobile. AT&T network SIMs use ERASE or ATT.MXKEY.
Check which network your SIM is on by looking at the SIM card or your Boost account details.

Guide
Full setup and troubleshooting notes
Before changing the APN
Boost Mobile is in transition. Most new activations use the T-Mobile network, but older SIMs and AT&T-based Boost SIMs still use the AT&T network. The APN you need depends on your SIM type.
If your phone is Boost-branded, the APN is usually pre-configured and does not need manual changes.
APN by SIM type
- T-Mobile network SIM (newer): APN `Boost_Mobile`. MMSC `http://mm.myboostmobile.com`. No MMS proxy.
- AT&T network SIM (older): APN `ERASE` or `ATT.MXKEY`. MMSC `http://mmsc.mobile.att.net`. MMS proxy `proxy.mobile.att.net:80`.
eSIM setup
Boost Mobile supports eSIM on compatible devices. The APN is configured automatically during eSIM activation.
Hotspot configuration
Boost includes mobile hotspot on most plans. The same APN works for hotspot. If hotspot does not work, add ,dun to the APN type.
Testing
After saving, disable WiFi, toggle airplane mode for ten seconds, and test in a browser.
Before contacting support
Final checks if data does not work
- Confirm you are using the correct APN for your SIM type (Boost_Mobile vs ERASE).
- Set APN type to default,supl,mms and add ,dun if hotspot is the issue.
- On dual-SIM phones, confirm that the Boost line is selected for mobile data.
- Check that your Boost plan is active.
- Toggle airplane mode for 10 seconds after every APN change.
