I just tried that in Quebec from Virgin Mobile (Bell) to Vidéotron using a Samsung S10 and a Samsung A8, it's working fine for me.

I can't verify it is send over SMS or MMS though. In theory there's no reason for my cellphone to send it over MMS.

The exact word used: secure communication

Turn off your data and disconnect from wifi, then try again. I believe that will force it to send via SMS. You might need to go through your client's app settings.

The Google Android client is nice because it displays what protocol it is sending over. It is important to confirm that it is sent over SMS. Also, it is important that the words "secure communication" are sent in all lower case which I see that you did.

Thank you for taking the time to test this. If you are sure it is being sent over SMS then I will add your entry as an example where it can be both sent and received

I just tried without Wifi and mobile data (good idea!), it was send and received correctly.

I did it from my S10 to someone else A8.

What client region was the twilio data center? What was the exact text sent? Are you comfortable to disclose the make / model of the receiving cell phone as well as its carrier service?

I just tested with twilio as well. I was able to send this string:

"secure communication"

from within the twilio API, via pure SMS (no imessage, etc.) to an iphone SE with a US Mobile (verizon MVNO) sim card.

Was sent from a US number to a US number.

No issues.
