Calling via the Voip.ms app on Android works fine.
But I do not consistently receive messages unless I deliberately keep phone on and app running. I end up having to search through my email (which I use as a backup delivery) to reconstruct conversations, which, is basically, unacceptable, as it only contains received messages and no contact info save the phone number.
It always works when I’ve deliberately opened the app and the number is registered. It does not always work (but sometimes does) when the app is in the background, or my phone is off, or not connected to the internet. I disconnect frequently and on purpose, but I still need to successfully receive messages.
Is anybody else having this problem? How can I resolve it—and keep the proper, threaded UI for text messages?
