I have two contacts with belong to the 5 people I call and SMS most, and their numbers are almost the same except second number, i.e xAxxxxxxxx and xBxxxxxxxx. One another person I know has problems with Jolla Phone with these same contacts with exactly same symptoms. Long time ago I did send a SMS to both of them creating a conversation, and sometimes SMS sent to one of them did go to both of them - maybe because I was responding to the group conversation. I could make sure the message went to right person by creating a new message instead of replying to previous message.

The contacts are not linked to anything (even though I sync my contacts via CardDav to Nextcloud, the other person with same problem doesn't)

Since update to Iijoki ( this has become much worse. Now even calls do get mixed up, so when I call to B I usually end up calling A, and I cant recall having any SMS delivered to B - they go always to A, sometimes twice. On incoming calls I feel as the phone shows number correctly, but while calling back to missed call i get most of time only to A. I think this has been the situation since upgrade, although haven't been calling them after update except recently.

This is related to but now it is no more about SMS only.

I have this same problem, one contact starts with 0500 xxxx and another with 0400 xxxx and those get mixed in my Jolla. BUT problem is not only in Jolla phones, also in Android at least. Those both numbers belongs to same family, dad (my boss) and his son so you really have to be careful how to answer or what kind of messages to send... :) So this problem is not so unusual.

adding country code won't help ?

@pawel, I don't think it will help because the classification is done via the LSB's of the phone number.

And as @japsi says, it's also present in Android phones... Actually I do remember coming across that kind of behaviour with my wife's Symbian phone too and that was what, 8 years ago or something.

I suppose every phone nowdays works like this.

Country code on both, either or neither contact does not effect at all. During past decades I can't remember hearing about this kind of problem on anyone I know (mostly Symbians, a few Windows Phones and Androids, of which probably Galaxy S3 is newest).

I can guess what's it about, probably.

The system mixes up the numbers because it thinks that the first digits are area code. The reason for this is (I think) that when there is an incoming call it can be from for example (+358 50 xxxx xxxx) or from (050 xxxx xxxx) which both mean the same person, hence only certain number of LSB-digits is considered an identifying key by the system.

I bet it is extremely rare for anybody to have 2 such contacts that differ only in the MSB-digit !

(but of course in an infinite world anything is possible, which is demonstarted by your case....)

a 'demonstarted' case?, where can I get one of those for my demonphone? :D (autocorrect?)

Obviously it's a padded case you use to carry the started demons in.

Handy unless the airport customs people happen to stop you; they'll be in for quite a surprise :)
