APN Setting and Troubleshooting 2026
What’s changed
Since ~early 2026 users are no longer required to enter values for MCC and MNC as part of APN settings. APN settings will be published by your carrier; be sure to get up to date data.
One would hope that the APN data will match
- on your SIM card,
- provided on /e/OS install and
- your carrier’s latest APN.
APN will likely fail if the SIM card data cannot be updated to exact current values.
Easiest

I could research this further, the AOSP “presets” are organised by country. I find Boost “presets” in USA are you there.
Is there any chance that this device arrived Carrier locked – 4 ways to check if your phone is carrier locked. This is very common in USA.
Thank you for your reply. For reference, I do have a solid WiFi connection and my phone is not carrier locked.
I still see the screen stating “Access Point Name settings are not available for this user”. It does have the three dots and the plus symbol in the top right. I first tried the three dots, then reset to default like you said. I put the phone in airplane mode and waited, but when I tried to connect I had the same issue (able to call/text but no internet). I also tried resetting APNs then restarting the phone with no luck. I then moved onto trying to manually add an APN, and filled in this:
The ones I left blank I did so because I was unsure what to fill in based on the link you provided. When I went to save, it went away instantly and nothing else showed up, I am still seeing the blank list of APNs with the message that they are unavailable for this user. Any advice on where to go from here? Any idea what to fill in for the spaces I left blank so maybe saving works this time? You are correct, I am located in the US.
The above is what you need. The carrier published method to set APN is the primary source.
And don’t forget the first suggestion:
If I were to research this further … I would be doing so in the case /e/OS “presets” are in error compared with carrier documentation.
