If it looks like this in the picture. This is the do not disturb, and to remove it you just turn off the do not disturb function

If its not this then we would need further details.
Like is it when you are trying to do something. Is it in an app
Or something else

[kazz4662]

Hi thanks but no it is on right of screen

[kazz4662]

Circle with diagonal line through middle. Been suggested its interrupted mode ?? Or no signal but I am receiving messages ?

It basically means that you don't have a mobile network access/coverage. As you have Wi-Fi on, you are still connected to internet and receiving messages.

Yes that's definitely no mobile signal.
Have you changed SIM card recently. If so you will need to contact you network provider to activate the card or you can go onto your network provider app/website to do it, if they support this.

In the phones settings, then connections.
SiM manager. Is the toggle on for the SIM card

You need to check your SIM, or contact you mobile carrier and see why your SIM has been turned off.

This is not a "no signal" icon, its a "SIM has been turned off" icon.
