+1 to this question. I am looking at purchasing this radio for my SOTA activations. This will be a dream feature to have. BTW I am completly new to APRS.
Looking at the response below @EA2CW, the newer version should have a similar or better feature.
Blockquote Anytone 878 is perfectly able to send SMS to SOTA using D-APRS (I mean DMR SMS, using some DMR repeater at sight, better than analogic APRS on 144.800 simplex)
Looking forward to hear from the users.
