When you launch your phone app does this show

Actually that used to be the case but now it simply wont connect, no texts can go out etc. Like the SIM isnt there, except it is and the phone acknowledges that.

If you try the sim card in another phone does it then work ?

[SteakNinja]

Yes.

[SteakNinja]

I initially had it in another phone where it was working, but didnt want to carry two. I dont currently have another phone to test, but I can give it a try later if I can find one.

Ok @SteakNinja

It's just a process of elimination to rule out the sim card.

So as per my screenshot you do see the same in your phone apps dialer pad.

[SteakNinja]

Yes, see the above reply of my dial pad. Mine looks slightly different because I have associated an image to each SIM, but its the same thing. SIM 2 does seem to say Unknown in settings though, instead of its phone number.

[SteakNinja]

I think the SIM might be faulty... see below with just the O2 SIM in the phone (slot 1).

[BandOfBrothers]

Yes that's the same as mine.

I've put the 2nd sim mobile number in...

Settings > Connections > Sim card Manager > Dial Sim Always On > Phone > Key in the mobile number.

Have you done this ?

[SteakNinja]

I did do that from the start, but it didnt seem to work. There was some confusion with the SIM, as my office had two numbers on contract for me... its possible that they gave me the wrong number for the SIM.
Yours also says Unknown?

[BandOfBrothers]

Yes.
