Call barring password

Hello everyone

I would like to block roaming calls on my prepaid SIM. The setting only requires a password. Where can I get this? Is a Huawei Mate 20 light.

Can someone help me with that?

This is probably the device password that you set and need after switching on.

Not at all; I’ve already tested all of this out; it is neither the SIM code nor any other PW; and to turn it on/unlock I have the fingerprint or I draw a pattern and I can’t enter that there.

@Ricki56 Have you tried it with PIN 2? If that doesn’t work, support can block your roaming.

Thanks, but on my card that I got with the SIM there is only 1 PIN and the PUK.

And I don’t want to discuss with Swisscom Support at the moment, it’s enough from last time😏

I tried attaching the photo to the card, maybe it will work.

Greetings Ricki

Hello @Ricki56 Maybe a little late, but maybe it can still help.

There is a code that must be specified for certain services that can be activated via USSD code. If your cell phone triggers this USSD code in the background, then it would be this code that you need. By default this is 0000. Give it a try.
