ADDITIONAL INFORMATION:

What exactly do you mean?

I have very rarely (much less than even 1%) experienced SMS not being sent problems but was never able to narrow it down to my phone or SFOS; maybe the recipient is not able to receive it right now? Maybe something’s off between sender and receiver?

What exactly do you mean?

=To reproduce this one someone has to send me a sms.

Yes, I understand that the cause can be multiple and not necessarily sfos. What surprises me is to receive the messages with another device (not sfos).

Ok, so that’s what “expeditor” means.

And I misunderstood; I thought somebody does not receive your sms.

I trust you made extensive tests;

This reminds me of common discussions about different mobile providers and their “quirks”.
