I’m using Groundwire and I did a test of trying to sent a photo of my dog from one of my DIDs. I immediately got a “message error” and the message didn’t go out.
I contacted support and they told me that wasn’t supported via the SIP protocol they use.
It’s not a show-stopper for me - I have other ways of sending images - but sending images does work using the TextNow VoIP app. It doesn’t with Talkatone though. So it seems to depend on the app.
I guess using apps meant to handle that where both parties are signed up is better for that use case: Apple Messages, Messenger, WhatsApp, Signal, etc.
If you want to be able to send a photo from your phone and have it look like it is coming from your VoIP.ms number, just enable email to SMS, and send it from your phone using a service such as ProtonMail or Tuta Mail. You can set up outgoing email to SMS without using the service in the reverse direction.
I was pretty sure I had tested this, but to be sure, I just emailed a short message with a photo attached to sms@voip.ms (you have to configure the service before you can use it), and I received it on my real mobile number with the photo.
I appreciate your response, but to be honest find it too complicated to follow.
I think I will just use other methods to send photos. For example, my TextNow VoIP works find for that, albeit a bit slow. Or I’ll arrange with the other party to use a mutually accessible alternative app better suited for that, like iPhone Messages, FaceBook Messenger, WhatsApp, LINE, or Signal.
A month ago, directly above this comment that I’m making now, DavidR teased an upcoming feature of some sort (presumably related to MMS at VOIP.MS). Has he yet revealed anywhere what he was referring to?
