Hi,
just sent an SMS to 2 different persons, but it only appears in 1 bubble and the info "sent" and "receive" are both crossed, but I don't know if both of them really got the message or not.
On my old phone (Wiko Cink peax 2), if the SMS was sent to 4 different persons, then it appeared in 4 different bubbles and I had the "sent" and "received" info for each of the bubble, when the recipient put his phone on in the morning for exemple.
