SIM card problem

[Members_eAgNWAP]

I bought new phone (samsung galaxy s22) and everything is fine but my SIM card keeps disconnecting. it says that my SIM card is unknown and disables everything.(it happens maybe every 3-15 seconds) even when is connected it says unknown number and in my SIM card status it say that: IMS registration status not registered.

its not a new SIM card because I have used it on previous phone (realme 😎 and it works fine

Go to support at the bottom of the members app. Go to diagnostics and test sim card. See if it comes up with any faults. If it's new contact where you purchased it from.

Make sure you have the correct apn settings for your carrier, I suspect that you may need a replacement sim card and a chat with your carrier would help resolve this.
