Can send GSM/SMS but can't receive on MTN

Image
 So this is a post about a weird symptom when you get a new simcard from MTN. I have also seen it on CellC. Basically: - internet works (TCP/IP) - GSM call outbound works - GSM SMS outbound works inbound GSM does NOT work Meaning you can't get OTP / 2FA SMS messages e.g. from Whatsapp etc. Nuisance! Ensure mobile data and signal are active (LTE/5G, not Airplane Mode). Check if you can send a normal SMS to a friend. If yes, issue is inbound only. Disable iMessage and FaceTime (Settings → Messages / FaceTime → Off). Restart the phone after disabling those. Check SMSC settings Dial *#5005*7672# (note: might fail on newer phones).

Boot MacOS under VirtualBox

Introduction The following steps are needed to boot Mac OS under VirtualBox. I tested it using Mac OS X 10.13. I can't guarantee this works. You'll need a source/original mac to copy the OS install. Probably Apple won't approve of this because they want you to buy their original hardware, but sometimes you need hosted VMs in the cloud or similar, and they don't really offer that. Steps Commands below are typed in a command line like the Terminal. 1. On a Mac, do this to download an installer disk: softwareupdate --fetch-full-installer --full-installer-version  ... OR download from the app store. If the operating system you want to install is out of date, ie if the Mac tells you the installer is damaged, set your Mac date and time to however many years ago that operating system came out, and turn of automatic date and time in the date and time system preferences. That way the signature of the installer disk / bundle will still be valid (it is invalid if it is older than ...
