I can’t see your MMS settings.
Thank you! I can’t find where those are in the settings; how did you get there from the main Settings menu?

In the SMS app, tap on the 3 lines with the DOTS>
Then tap the SIM you want to Edit,
Thanks, that was helpful. I don’t have the same exact settings as you (maybe because of different providers?) but I was able to see that “allow MMS while roaming” was off (so I turned it on-- although I am not sure that this will completely fix my issue as I have missed texts while at home connected to WiFi too). Unfortunately I don’t see the setting you have in your first screenshot that had MMS messages turned off.
Thank you for sharing this. Are you switching from an iPhone? Because perhaps I can clarify how messaging works on Kompakt:
Standard SMS text messages don’t rely on Wi-Fi or mobile data at all. They use the cellular network’s signal (your carrier’s voice/SMS channel), so even if you’re connected to Wi-Fi at home, SMS delivery still depends entirely on mobile reception.
What can sometimes cause confusion is that on iPhones, many messages are sent through iMessage, which does require data and can be delivered over Wi-Fi just like WhatsApp or Signal. So if someone is used to that system, it can feel like texts should arrive as long as Wi-Fi is available.
The Mudita Kompakt native SMS/Text app only uses traditional SMS/MMS services, which means:
Wi-Fi connection does not affect incoming SMS- You need a strong cellular signal for reliable delivery
SMS does not travel over Wi-Fi or data networks
If you’re experiencing delays or missing texts, it’s most likely related to mobile coverage or a carrier setting, not the Wi-Fi connection.
Let me know which carrier you’re using and your approximate signal level at home, and we can take a closer look together.

To all the people who are missing messages:
You can have mine. I received a bunch of spam messages, there are enough for everyone. You can have them for free

Thank you! This is helpful.
I am in the U.S. and use Mint Mobile. I have pretty good service at home (3-4 bars) and didn’t have issues with missing texts prior to switching from iPhone to my Kompakt.

This could be the issue. Did you disable iMessage? Is your phone number still connected to iMessage?
iMessages are sent through Apple’s servers and require a data connection, unlike standard SMS, which uses your carrier’s network. If you switch to an Android device without deactivating iMessage, your phone number can still be tied to Apple’s messaging system.
This means that any text messages sent to you from iPhone users (which is the majority of US users, tbh) will still try to send via iMessage instead of SMS, which could result in you not receiving those messages. This happens because your number is still registered in Apple’s system, and iMessages are directed to your old iPhone instead of the Kompakt device, which uses AOSP (Android-based)
Solution: Before switching devices, it’s crucial to turn off iMessage on your iPhone.
Unfortunately, that’s not the problem. I turned off iMessage and RCS when I got my Kompakt in early September, and I’m also missing messages from BOTH Android and iPhone users.

@anna.lynne.gilmour Hmmm, that’s interesting. Let me ask my team if they have any more ideas.
