In that case can you check the details of the APN you’re using.
Settings > Network and Internet > Mobile network > Access point names > [tap on the APN] > APN type
needs to contain “dun” either upper or lower case.
If that value is absent, you may be able to add it manually (don’t forget to save your change with the three-dot menu top right). However, nowadays carriers often set APNs read-only to prevent users from messing about with them. In that case I’d advise you to check with your carrier in the first instance.
If the value “dun” is already present for the “APN type” list we’ll look elsewhere.
From the point of view of the device and the OS version you’re running there should be no problem using the hotspot feature, I used mine yesterday.
Definitely. I’m using it daily lately since I’m far from home and use exclusively my phone to access Internet: It’s much faster and way more secure than hotel or client WiFi…
It works very well, except under Windows 11 where most of the time I have to manually tell the computers to connect to that SSID. Linux/Mac do connect automatically.
Note there is a feature which automatically switches the hotspot off (to save battery) when no device is connected to it, and when it does, it will give you an error on the top status bar. Given the thread’s actual title I thought you meant that.
This automatic switch-off is actually a good thing (I do sometimes forget to switch it off when leaving in a hurry…), but if it bothers you, you can disable it in the WiFi hotspot settings. It doesn’t change anything to hotspot reliability anyway, if a device is connected to the hotspot, it will stay active for as long as the phone has enough battery and a mobile data connection.
And what values did you find for the “APN type” field?
Bear in mind that carriers vary in the way they treat services like hotspot. Often their treatment will also vary from one model of phone to another, so just because the hotspot works with a Remi Note 9 and same APN settings and same carrier doesn’t necessarily mean that your problem isn’t related to the carrier+phone_model combination.
