I have been getting this message for a short time. Two changes are possibly the culprit:

  1. I switched to cricket from tmobile on a tmobile phone. Shortly afterwards I started getting these.
  2. I have a new ROM. OctOs M, which is based on Cyanogen.

I strongly suspect #1. I've never seen this message before it started happening, and I don't know what its trying to say.

enter image description here

Phone is a T-Mobile Note 2. When I started with Cricket, it was still inadvertently locked, but I worked with T-Mobile to get it unlocked.

This phone physically cannot use more than 1 SIM.

If you didn't know, "Signal" is an app by OpenWhisperSystems. Its a replacement sms and mms app. I have deregistered and reregistered with the app, and that did not affect this issue.

I did not do a factory reset when switching to the new service, so I wonder if something is up with Signal?

  • Is the ROM designed for dual SIM devices? Feb 17, 2017 at 11:51
  • The ROM is designed for this particular phone, but they do have others they build at the same time. Presumably it's an automated process though. Feb 17, 2017 at 11:52

    Potentially. Apologies I don't know the device very well, perhaps there's a dual SIM variant and the ROM has been designed to support both. If you haven't got an answer later on I'll have a dig about when I'm actually at a device I can search on properly. Out and about at the moment Feb 17, 2017 at 11:54
