When I'm abroad it often happens that jolla shows that "There was problem sending message", but the SMS are actually send (and sometimes they are not send). Is this related to roaming or it is a bug of the system? Cheers, Mariusz (the latest official version of Sailfish 2.0.1.XX).

@Marius i think it's a problem related to the roaming. I never had this issue :-/

I would also say that with Jolla I have seen more weird SMS errors when roaming than with Nokia phones I was using earlier. Both without any protocol level logs it's impossible to say who is the culprit. Some countries have always had worse networks than others. And in some countries network quality deteriorates while operators are engaging in price wars and laying off technical staff.

I've also had this happen but not very often. Usually when roaming I tend to get problems with delivery receipts, though, in that I suddenly stop getting any, and then several days later all my SMS have the same timestamp because of the delivery receipts suddenly getting through all at the same time.

For delivery receipts this is more like a protocol feature. Delivery receipts are sent from the network to the phone on an best-effort basis. There is no confirmation whether the delivery receipt was received by the phone. So it it is lost, there will be no 2nd try. Lost delivery receipts can always occur, but in my experience it's much more common when roaming. Don't know why exactly. Maybe the route from the short message center in your the home country to the roaming phone consists of several links which are all best effort?

(In contrast SMSes proper are resent by the network until a confirmation from the phone is received. Because phones do not eliminate duplicates, one sometimes receives the same message twice. I think this is generally related to crowded or very weak networks. Don't think roaming makes a difference here.)

When I wrote "weird errors" I referred to worse things than these protocol "features".
