To me the real issue here is why are people using SMS which was designed only for "Short" messages and complaining that it does not work right for long messages. The reason for Short is because the messages are sent on the control channel. Short was determined by the fact that one SMS message is the longest complete string that can be sent in the control channel without fragmenting. (also they are sent when the system has time in between all the other signaling on the control channel which can cause significant delay between the parts). Each time a SMS message is sent it blocks using the control channel from being used to setup calls, etc. Rebuilding a broken up message is a function of the phone not of the system.

You make a good argument, but the reality is that the use of the technology has evolved, and most other carriers have evolved with it.
Here is the reply from MTS:
At this time I am not aware of any advancement in that area. It may not only be on our end, if the text messages are not received in a timely manner from the other provider, it may be unable to be rebuilt.
Guys, this issue is not specific to MTS itself. I tested this issue both with a rogers friend and with my dad and his MTS blackberry.
I send a very long text from my MTS android to a rogers iPhone which broke up my message and it arrived on my friends rogers iPhone out of order and in chunks. a long message from the rogers iPhone to my MTS android was also broke up out of order.
We sent back and forth the same text that broke into 5 pieces between rogers and MTS between my MTS android and the MTS blackberry, and both ways the message constructed properly into one long message.
This issue only happens when sending messages between rogers and MTS. rogers to rogers and MTS to MTS works fine.
All of you are confirming that Concatenated SMS does not always work on CDMA phones. It depends on which phone you use and which technology the phone is. It works well on GSM and HSPA (GSM related) but not so good on CDMA. http://www.developershome.com/sms/smsIntro.asp Notice that it mentions that SMS was developed on GSM and then ported to CDMA. Since CDMA is no longer being actively developed I would not expect to see any new features being added or any bug fixes unless security related bug is found.
If you are looking for more information Google "concatenated SMS" there is lots of info out there Remember SMS was developed when cellular phones were just being developed and SMS was squeezed into the control channel in with the signaling that indicates to all the phones on the tower where the other cellular towers are and when a call is being sent to a phone, etc. it was intended to generate revenue from the spare bandwidth on the signaling channel not to be a primary means of communications. It works great for what it was designed for and is much more popular than was ever imagined by the designers of the system but is still constrained by the limits of the speed of the control channel which cannot be changed without replacing every cell phone on the network. Because SMS is not time critical like the network causing someones phone to ring it is often delayed when the cellular systems are busy. Message parts arriving out of order is more likely because some of the parts were not received error free on the first try and had to be re-sent so they ended up being received out of order.

No, I'm confirming that it doesn't work properly on CDMA or HSPA. I had hopes that when I moved from CDMA to HSPA that this problem would be corrected, it was silly of me to think that would be the case. And you're right, the phone is involved as well, but if the network isn't setting it up properly, then the phone can't rebuild it. I find it hard to believe that everyone with an iPhone or Android phone on MTS has a problem with the phone. (Disclaimer - I don't know anyone with an iPhone on MTS so I can't reliably say what happens with them.)
MTS has given their answer, and it looks like we're stuck with this problem.
Got a longer text message today, and the pieces came in order. Don't know if they fixed something or what?
No, it's "random." Sometimes luck of the draw puts them in order.
A few days ago my friend on Rogers sent me a screenshot of one of my messages (short message, under 140 characters) that appeared in 3 random order chunks on his phone, like 4 words in each chunk. I had mentioned this briefly in an earlier post, but didn't type it correctly (I can't seem to edit my posts.) I understand the MTS is probably not going to get long concatenation working anytime soon, but why would a short message break up?

It is a problem in the communication between the Rogers and MTS network. I don't know if there is anything either company can do about it.
Why doesn't the same problem exist between Bell and Telus? They have the same arrangement on the HSPA network in Alberta that Rogers and MTS have here in Manitoba.
CDMA is proprietary to Qualicom. They charge a license fee for each feature deployed by each carrier unlike the way it foe GSM where it is licensed by the GSM association almost free of charge. You can ask the same question as to why can't MTS prioritize data on their CDMA network based on user. They can't because they did not buy the license that is why, and I suspect that it is the same reason as to why it works on the other carriers and not with MTS.
