Replicant

Reading again my question, I realize it is probably not clear.

I wonder if in Replicant there is any mean to avoid automatic sending of confirmation when I receive and read a sms ?

[You're able to <edit> your posts [in this case the first one], if you think things are not clear enough].

I saw I can configure my phone to ask for sms confirmation when the sms I sent are received and read by receiver.

I think you mean the "SMS delivery report"
"Some providers allow users to request delivery reports, either via the SMS settings of most modern phones, or by prefixing each message with *0# or *N#. However, the exact meaning of confirmations varies from reaching the network, to being queued for sending, to being sent, to receiving a confirmation of receipt from the target device, and users are often not informed of the specific type of success being reported."

• If I understand you correctly, you fear to send a SMS-confirmation about a received SMS (and probably have to pay for it)?
  If you mean the "SMS delivery report", than this is not the case, as you can read above.
  If you want to try an alternative SMS app, you could give "SMSSecure" a chance:
  https://f-droid.org/repository/browse/?fdid=org.smssecure.smssecure
  this app could let you make some more settings-changes in this context.
• If you fear to receive hidden SMS and your device will (hidden and free of charge) answer in the background (e. g. your position):
  Then you have to inform yourself about "Type 0" or "Stealth" SMS, for example over here:
  https://github.com/SecUpwN/Android-IMSI-Catcher-Detector/issues/69
  Probably this app "Android-IMSI-Catcher-Detector" itself will get protections against that kind of SMS in the future. You can give it a try over this sources:

Well, the delivery report has to be sent to the operator, else it will keep sending the message until your device acknowledges it. If the operator sends a message back to the sender notifying him that you received the message, then there is nothing you can do to prevent that. However, if it's up to your device to send the confirmation, then you might be able to block that, either by choosing so somewhere in the Settings or by implementing this feature.

AFAIK SMSSecure does use the traditional SMS network, so it doesn't solve the issue (unless I'm mixing it up with TextSecure, but I'm pretty sure TextSecure is the one doing XMPP). And wasn't it forked recently?

TextSecure has kicked out the SMS encryption functionality,

which was reanimated in a fork named SMSSecure,

And yes, SMSSecure doesn't use XMPP, (SMS only).
I (spongy) asked for an implementation-possibility like you described on the project page: https://github.com/SMSSecure/SMSSecure/issues/163

Yes, I have seen this, but I choose to write a new one to update the topic. :)

Absolutly !

Yes, I know how it works, but I wondered if Replicant can be configured to not sending the report to sender. :)

I have seen this, it is not my actual interest but it could be an interesting side effect.
I looked for an app which allow to not send a report

Probably this app "Android-IMSI-Catcher-Detector" itself will get protections against that kind of SMS in the future. You can give it a try over this sources:

Ok, so I understand the basic sms application does not allow to configure the sending of sms report.
Thank you to both of you for your answers.

... and SMSSecure also don't: https://github.com/SMSSecure/SMSSecure/issues/163

Thank you anyway
