My employer uses email-to-SMS to send IT outage alerts to our IT team. The tool (internally developed, but not easily modifiable) takes a message of arbitrary length, applies some header information to the text, then splits it into messages of 150 characters, sending the message as one or more emails (or so I'm told). My colleagues on other providers have no issues. and a colleague on T-Mobile with an iPhone 7 has no issues. I, however, have problems receiving messages. I have a Samsung Galaxy J7 Prime (but I had this problem with a Galaxy S5, as well).
When a message is sent via the tool described above via my tmomail.net address:
- If the messages is less than 150 characters, I will not receive it.
- If the messages is more than 150 characters but less than 300, I will receive the SECOND message ONLY.
- If the message is more than 300 characters but less than 450, I will receive the THIRD message ONLY. (I assume that this continues)
I have asked for logging info or a copy of the message being sent from the tool, but so far haven't had any luck with our internal support.
Here is an example of the message I'm NOT receiving (company info redacted):
GlobalOncall@employer.com / Message from Global Oncall / 3/19 14:11 (UTC-7) username, email@example.com - This is a test message to see if there is an issue with the global oncall paging tool and to 1/2
And here is the remainder that I DO receive:
Message from Global Oncall / get a sample message in hand for support. 1/2
Note that the second message should be labeled 2/2 if it comes through correctly, but it is 1/2. I'm trying to validate if it is our tool doing the paginating or if it is on the T-Mobile end.
In any case, I'm hoping someone can point me in the right direction for resolution before this gets to be a much more serious problem.
Thanks in advance!
