I noticed, whenever I am in foreign country (i.e. DATA ROAMING) I can connect other devices to my android phones via its hotspot, but they (devices) have restricted access to internet.. In other words: My phone, where I would like to share internet via operator's data in foreing country roaming DOES have internet access, but devices connected to it via WiFi hot spot do NOT. As soon as I return to home country, the problem disapears and tethering works normally. This I've noticed on 2 Android phones I owned and tried: Nokia 6.1 and Motorola G10.

Vendors claim they do not have a fix for it, operator also claims he is innocent. Does it look more like a problem of Andorid OS, foreign operators, or my home operator ?

Edit: (based on Robert's suggestion)

My home country: Slovakia (Not to be confused with Slovenia)

My home operator: 4ka

Foreing countries traveled: Austria, Czech Republic, Germany, Netherland, Belgium, France, Luxemburg

Foreign operators: Any one I encountered. Really do not know their names.

Can anyone help to identify the source of the problem, please ?

    Unless somebody else experienced the same problem I don't think you will get an answer. The main problem is that network routing is operator specific and when roaming there are two operators involved. So your problem may be caused by the combination of two specific operators. Thus I recommend to edit your question and exactly name your home country, operator as well as the roaming country and the used local operator. Besides that I would recommend to modify your question and ask how to diagnose such problems (-> identify which part is causing the problem), instead how to solve.

  • I have the same problem with operator 4ka. I have checked hotspot in roaming: Czechia, Poland. I checked it on many modern Samsung phones (more than 3) and no internet on hotspot connected devices. The strange thing is that it works on a very old Samsung Note 3. I'm really curious what that? If I good remember it was working before (2020).

  • @user389120 Well, so this looks pretty much like a problem of the rookie operator 4ka :)
