  Please screenshot, mspaint, or google image what you're seeing.

  Have you contacted Amaysim support? Could be a roaming issue?

    image updated above. it's very interesting thing. Only optus related services are not working.

  Does it also do this in safe mode?

  I'm guessing your phone is now blocked but hasn't hit the imei blocked registers yet.

  person is industry professional and working in local area so doubt it's dodgy

  This means nothing. Ever heard of white collar crime?

    If phone is locked. then it should not work on any network. It works on other networks except Optus. I checked with Telstra, phone is not locked at all. Vodafone also works on it.

    Samsung has no clue why is it doing it and what the error message mean.

    Also checked with optus who said there is no way they can block a phone just for their carrier.

  The error shows up if:

  1. It's locked to a carrier,

  2. Reported stolen (insurance fraud by seller?), or

  3. Is blocked (see 2. or it was stolen to begin with).

  Even if the seller seems, or is, legit, maybe they bought it used from someone else who reported it stolen just now, or who stole it themselves. Or the seller stole it from their shop (if it's not their own business?) and now it's been reported stolen/missing.

    Telstra sim works fine. Checked with them and confirmed the IMEI is not locked to at all.

    Checked with samsung, they confirmed the phone is not locked to any network either. They have not seen this error before.

    So it's really interesting situation.

  My guess is that you have an overseas model that is locked to a carrier. What is the model number of your phone?

    I thought the same but then checked with Samsung Australia, the model is definitely Australian and is covered by Samsung warranty.

    Very interesting situation making on sense, not sure if it could be related to any frequency support thing that Optus uses.

      If it's not an overseas model then it's likely it's a sim issue. You said you've tried other optus sims. Are you sure they were active? It is a very strange situation. I hope you get to the bottom of it.
      Edit- I just tried an old inactive Optus sim in my S9 & it came up with the triangle MM symbol but said "sim not provisioned" which is a different error to what you're getting so I'm barking up the wrong tree.

  I'm having the exact same issue with an Amaysim account I just signed up to.

  Strange thing is, it allowed me to make a phone call but straight after, the MM - Phone no allowed notification.

  Did you ever resolve this?

  (Don't have any other sims to test with currently, but heading into the Telstra shop tomorrow to see if they can help - lol)

  I have a S7 Edge - so not exactly the same technically :P
