Affected app version

1.0.1

Affected Android/Custom ROM version

Android 11

Affected device model

Nokia TA-1157

How did you install the app?

F-Droid / IzzyOnDroid

Steps to reproduce the bug

1. Have a SIM card inserted in slot number 2 (SIM2) in your phone
2. Set a conversation to send messages using SIM2
3. Receive a message on SIM2 for that conversation
4. From the notification that pops up, tap "Reply" and send a message

Expected behavior

App should answer using the preferred SIM specified by the user in the conversation with the SMS sender, or at the very least automatically defaults to the SIM that the message was sent to.

Actual behavior

App will always send the message via SIM1, even if there is no SIM card inserted in the SIM slot number 1.

Screenshots/Screen recordings

No response

Additional information

This is critical for me as some of my clients won't look at messages from phone numbers they don't recognize. So if my app sends replies with the wrong SIM card, clients might never receive critical information i sent them and assume they have received and read as being from me.

originally reported by @Zoyolin in the SMT repository: SimpleMobileTools/Simple-SMS-Messenger#723

I've noticed that when I reply to a sms received in the notification, the send fails as it attempts to use my first sim card. In the main sms view, sim card 2 is the default one and also system wide for sms (and internet and calls).
I'm on android 11 on a fairphone 3. Build 8901.4.A.0023.0 release-keys.

Just in my case default is SIM1 but when replying from notification it uses SIM2

[Cwpute]

Interesting. Have you specifically set your SIM1 to be the default ? Have you done anything that would tell your device or app to use a specific SIM card over another ?
I'll take a look myself.

Yes, system level default is SIM1. And stock Messaging app works well.

I have to say, I sometimes fell victim to this bug, I've got 2 SIMs, one for mainly (cheap) internet, one for mainly (cheap) calls and SMS.
The SIM which I mainly use for calls and SMS sits in the SIM2 slot, and the one for internet, in the SIM1.
Now, when I get an SMS message (to SIM2) from a new/unknown number, and reply to it quickly (without paying attention if it goes out of SIM2), it goes out from SIM1...
Shouldn't the reply function work that it checks which SIM got the message, and reply with the same one?

^{Aside from that, the apps ecosystem is really great, good job Fossify!}
