@Vlad-Nirky Hi !, personally the first one I cited doesn't work well at all.. after the second better but not perfect either I have 4G which doesn't work for example... or at least 30 seconds when the phone just boots after nothing 3G only Thank you for your response

@yannesc Yes the ones on Focal get OTA updates.

@mark1250 Sending message with google messaging app in RCS mode should not be a problem, normally, it should convert to SMS or MMS if contact doesn't have RCS on his phone/carrier. But this is what should happens, and sometime with this kind of things it's not what really happens ^^
