Sim card stores the message service centre number. Similar to any other mobile global title, it has digits along with other information. A mobile operator uses SMSC for providing SMS services to subscribers. It is also known as a message centre number, located in HPLMN of a mobile network operator. Smsc or message service centre number is the Global title/Address of SMSC. For example, the nodes can be HLR, GGSN, SMSC etc. To communicate with the other nodes in the SS7 network, each node requires an address known as a global title (GT). I am not an expert, nor super knowledgeable about this, but this SMSC number seemed to be something that is read from the sim card and traveled with the card to each phone I put it in. Turns out I had a bad SMSC number in my sim card settings.

However, I was still determined to keep trying, I mean, what else could I do? That’s when I started doing comparisons between my phone and my wife’s phone. In the end, tech support didn’t solve my problem, because they didn’t know what it was. It is some poor soul who is getting paid minimum wage to read a script that tells you to do all the things I already did. They don’t really seem to know anything at the normal “entry” level tech support that you call. It is really difficult talking to my carrier’s tech support. It wasn’t my phone, it was something with the sim card or setup on my carrier’s end. If I put the sim card in another phone, it still didn’t work. Finally I tried flashing my phone back to stock and that didn’t fix it!īut then I realized something.

Then I reset my network connections in Android from the settings menu. I went through all of my APN settings, contacting my carrier and double checking them. While the above worked to force MMS and send my text messages, the problem still wasn’t resolved, so I kept at trying to fix it. ( YAATA texting app was the only one I found that did this.)
