Text Message via Email


How can I get text messages sent via email to appear from a single sender rather than each one being unique?

@tmo_marissa @balpaugh I can help explain this! I am the spam admin for @tmomail.net. Email to mobile is MM3 messaging. It routes through the MMSC, but if the message is less than 160 characters, plain text, no media content, the message format meets criteria to be redirected to SMSC for delivery. This is hard coded standard and cannot be customized per sender or recipient. The message is delivered over SMS 97xx/2300 gateway which is a random assignment. So this is why messages are not nested in the same conversation.

Those three slashes signify the plain text ASCII message format sender / subject / body. Why? Plain text SMS is the sum of the sender + subject + body = (<160 char). Plain text is the lowest denominator decision. If less than 160 characters, RFC standards commit the message to traditional SMS delivery because there is no transcoding or HTTP get required for such a basic message format.

When it's redirected to SMS, the sender header info is dropped in favor of SMSC gateway identity. The workaround is to force the messages as MMS which would be HTML, multimedia, longer than 160 characters, or include a subject which should force it to remain as MMSC message.

I understand this is a pain, as firefighters use them for CAD paging. This design went into place when the MMSC vendors were swapped out over 4 years ago and it's following RFC messaging standards. The old vendor used to route it down a static gateway but if that gateway was down or failed, nobody got their messages! For modern gateway redundancy, the messages need to round-robin to the nearest available SMS gateway and so the messages are not hashing to a specific exit.

Hi. I've been away on vacation so I haven't been able to test anything but I plan on doing so when I return later this week.

Thank you

Hi Marissa,

I had an opportunity to speak with a gentleman from the T-Mobile technical support in the area that deals with this specifically, and I believe that we’ve gone as far as t can at this time. I appreciate your assistance throughout the process.

Thank you,

Apologies, yes I worked directly with Bryan and explained some of the differences between VZW and T-Mobile messaging interface.

Good morning all! If I understand correctly there is NO FIX for this issue if it is under 160 characters. I receive numerous messages from a CAD system of which most must be less than 160 characters and therefore show up as random numbers. I was with ATT & Verizon and did not have this issue with them. Help!

@cdcarleton​ I sent you a follow request so that you can P.M. details to me about your issue.

So what's the verdict here?

is there a way to force it to MMS instead of SMS?

@srickar​ I am having the same issues as cdcarleton. Could you please help me?

Hey, all. I know there are suggestions in the reply marked correct on the original post here regarding ways to attempt to trick or force emails to SMS to come through as MMS. If you give these a shot and are not successful, then at that point, @srickar​ is correct -- our engineering team needs the type of documentation with account details that a trouble ticket with our Tech team can provide.
That said, I'm going to go ahead and lock this thread. If you've read through and tried the suggestions and are still having problems, please Contact Us​ so that we can get the examples documented and sent up for review! Thank you so much.

Hey @balpaugh‌!  This is a great question.  I tested on my phone (an LGV10) by sending some emails to my line through the 1XXXXXXXXXX@tmomailnet format, and because I have my email address saved as a contact, they appeared in the same message thread.  I'm not sure if that would work for a back-and-forth, though.  Can you try saving the email address as a contact and see if that works?

- Marissa

Thank you, but I’m not sending from my email so there is no way to add any contact information.

As you can see in this picture, multiple alerts can fill my screen rather than within a single text string.  I’ve not had this issue with other mobile carriers until switching to T-Mobile.  How can this please get changed????

Thank you,

Bryan

I'm so sorry, @balpaugh‌ - that image didn't come through.  Can you try again?

Also, I must have misunderstood your original question.  You referenced "text messages sent via email", so I assumed you were talking about the service that allows our customers to send SMS from an email system... hopefully the screen shot will make it a little more clear, but if you can give me some details I'm happy to help!

- Marissa

Hopefully this will come through better.

It is sending emails through your SMS gateway but they’re actually coming from my home automation system, routed through my Comcast email to you in the form of 16514422860@tmomail.net

When I get them on my phone rather than indicating that they’re coming from my email (which is what Verizon did) they show as coming from 391-1, 410-8, 371-1, etc…

Wow.  I wonder if the difference is that they're automated?  I'm sorry to come back to this, but have you tried creating a contact entry in your phone with no information other than a name in the name field and that email address, if your phone will allow it?

- Marissa

Yes, my phone my email client, they all have the contact entries. I really see no advantage to the way T-Mobile is handling these messages, even the ones I receive from T-Mobile on their specials, show up as coming from 747-X. There has to be a way to change that on the T-Mobile side.

I have to say, I'm at a loss here - my messages from TMO come from short code 456!  What kind of phone are you using?

iPhone 7 Plus

Have you been able to find out anymore on this issue?

Thanks for your patience @balpaugh‌ - I tested and tested and couldn't recreate this - but then I asked a colleague of mine who uses an iPhone.  He tested sending messages to his line using the tmomail address, and even coming from the same email, sure enough they appeared as unique messages coded with the same format short codes (970-1, 320-2) instead of in a single thread from one contact.  It sounds like this experience is not what you're accustomed to, and I'm sorry it's different than your previous provider - I can definitely understand that it's not ideal!  I honestly didn't know about this difference between the messaging systems on Apple/Android, and appreciate the learning opportunity and the feedback.  I'll pass it on!

- Marissa

Unfortunately, it's more than just "not ideal". It's very problematic as I get all of my security alerts that way and not being in a single thread makes it difficult to monitor and very easy to miss critical alerts.

I hear you.  It definitely follows that in this scenario, missing a message because of the way that they appear in your inbox has the potential to be much more important than just overlooking an average email.  I've already forwarded the feedback for you, and you're welcome to Community-2153 and work with Tech Support as well - but I feel like it would be irresponsible to suggest that we'll be able to file a ticket for something that appears to be the expected behavior/functionality of this service with iPhones at this time.  We do take customer feedback seriously (we used customer feedback to determine every one of the UnCarrier movements) so hopefully this will be a pain point that yields results!  I know this isn't the fix you were hoping for, and I'm sorry that there's no immediate remedy to the issue, but I do thank you again for posting and providing a clear example of how this affects you. 

- Marissa

I’m sorry but I completely disagree that this is the expected functionality from any phone. It certainly didn’t happen on my iPhone when I was with Verizon or AT&T and I had no reason to expect it to be any different with T-MOBILE. Since I see no apparent advantage for them to occur in this fashion, I truly suspect whether it is a desired outcome either.

How can I talk to someone with greater authority within T-Mobile? This is unacceptable and certainly NOT something I can “live” with for any extended period of time.

Thank you,

I hear you, Bryan.  Please let me explain the use of the word "expected" - I want to make sure you don't think I'm being dismissive of this issue.

I had two of my colleagues (fellow moderators here) test this by sending emails to their own iPhones, and their messages showed up in the same format.  Then I ran a search through our internal list of system issues (known and emerging) for any trouble with this type of messaging on iOS equipment and came up empty.  Because of that, I found it fair to state that this is the current expected functionality - the logic being that if there were a possible setup tweak needed, it wouldn't happen to other people; and if it were a system error, it would be listed in the engineering worklog. 

We may not be the change-makers ourselves but we have the ear of the powers that be.  I've leveraged an internal channel available for front-line employees to escalate customer pain-points and get them in front of senior leadership to report this, and also sent a message regarding this situation to our contact that handles iOS equipment.  This is the limitation of what we can do here in the Support Community.

That said, if you'd like to report this concern through additional channels, you can reach out via any method listed here: Community-2153‌.  I truly don't think it would be a bad idea to start with Tech; perhaps they are able to file a ticket for this - I just don't want to promise that and have you be further disappointed (and since this is a user forum, our team does not have the account access required to test this).  Thanks again for your time and for staying so engaged here.

- Marissa

Actually, I’ve already done that as well. I talked to one of the support techs who said they were going to check into something and get back to me and ultimately has fallen into a black hole. This is unfortunately my worst fear in dealing with large companies like T-Mobile.  Any issue they don’t want to deal with, they push off and ignore I’m sure hoping that I’ll just go away. Since I don’t have a name, every time I contact them, it’s like starting over and ultimately, I probably will get frustrated and eventually give upand move my business back to Verizon where I know it works correctly.
