My wifes Samsung A40 is part of a group of three new Smary sim card users. Today, out of the blue it stopped making or receiving calls. Anyone know how to fix this. Seems the A40 is compatible and VoLTE is on.
It's not listed as not compatible and I don't have another phone to check - we both use the same model. Mine seems to be working fine in the same model of phone. And anyway, why would it be working one minute and not the next?
