Hi,
I am hoping someone can shed some light on this.
I just signed up for T-Mobile a few days ago and now I cannot receive Short Code SMS from important entities like my banks and email providers for secure login authentication (2FA, etc.). I also haven't been able to get test calls/callbacks from places like a 3rd party voice mail provider, or Amazon customer support. I have been on the phone with them for days trying to fix the issue, these are the steps they've tried and I still cannot receive these SMS's or test calls:
-Refreshed my connection to their towers
-Reset Network Settings on my phone
-Toggled Airplane Mode
-Updated OS and got new Carrier settings/version pushed.
-Switched from Automatic Cellular Network to specifically choosing T-Mobile on my phone
-Turned off WiFi Calling
-Verified on their end that Short Code SMS is UNBLOCKED
-sent test messages of their own, which I received because it's...T-Mobile...🙄
I am using an iPhone so we do not have an option to block or unblock short codes, unlike Android devices. So that is a moot point.
I am on a MAGENTA series plan, this is not a prepaid or T-Mobile ONE plan, as I know those have issues with short codes as well.
If anyone can help, that would be amazing. Thank you so much
I can't send SMS to short codes, like 9811801, from Google Messages. But I can receive them.
It works from any other SMS apps, but not from Google Messages. Looks like Google Messages is appending the country code or something. Looks like a bug.
Am I the only one?
Twilio offers this along with their other telephony services. I haven't actually used their SMS service, but I've heard good things about the company in general.
For less than 1/100 of the price of a dedicated shortcode, you can start with a "shared shortcode" provider like TextMarks. TextMarks owns the "41411" shortcode, and you can lease keywords on it for use with your own applications.
You configure a callback URL, and any incoming SMS messages starting with your keyword get routed to your own web server as HTTP requests. If you respond with anything, your message even goes back to the user as another SMS response.
