Wi-Fi/hotspot closing on its own issue

[BLily]

I'm abroad and my hotspot started to close itself suddenly and cannot open it. Now wifi started to do it too.

Reboot the device

[BLily]

Did it but it did not work

So your hotspot and WiFi aren't working properly? Do you have a foreign carrier SIM in your phone?

[BLily]

They are not openning at all. And yes I have both TR and US sim but TR one never did this.

Try to reset mobile network settings under settings > general management > reset.
