Im trying to send a text to a 5 digit number and i get a response, "Service Access Denied", why?

@drockwell , did you have a chance to reach out and see if your shortcodes were blacklisted? 

I understand you may have never specifically requested a block on them, but you may remember a few years ago when "Premium" SMS were popular- folks could receive daily horoscopes and things like that and were unaware that they were being charged for a subscription on their phone bill.  For that reason, most shortcodes were automatically blacklisted with the cellular carriers unless you specifically ask for them to be allowed, or for only specific numbers to be allowed.

If you've reached out to T-Mobile and requested the shortcode blacklist to be removed and you still aren't able to receive them, you will have to check your phone's settings.  Depending on your device manufacturer and software version, the method could be different.  (Your mileage may vary..)

For Samsung: 

Settings>Apps>Menu (3 dots in the upper right hand corner)>Special Access>Use Premium Text Message Services>Always Allow

For LG:

Settings>Apps & Notifications>Special Access>Premium SMS Access>Always Allow

Para Apple:

There is not a specific setting to turn off/on Premium Messaging, but you will want to check:

Settings>Messages>SMS (ON) and make sure MMS and Group messages are on too.

If you've hit all of these steps and you still can't get shortcodes, you might want to do a little research and find out what the number is that is trying to reach out to you.  (Try searching online or calling the company directly to find out); then send a the message HELP to that number and see if you get a response.  For example, Walgreens sends out prescription status updates from the number 21525.  If you send HELP to 21525, you should receive a reply back with instructions how to contact them.

Hope this helps!

Make sure there are no service blocks on your account features.  I had this issue once and some setting had been opted into to block particular services.

Wow, that's no good @mnikatorr.

Is this the only number you're having trouble with? Can you test other short codes to see if they work? Just a heads up, if the short code is for an international number, we can't guarantee it'll will work.

Hola @mnikatorr‌!  Just wanted to drop in and see if you'd had a chance to test other short codes to see if this issue is isolated to a particular number.  How is everything going?

Im having the same issue is there a way to have this fixed?

¡Hola, @magenta1398000​! That's no good - can you fill in a few details for us? What type of account do you have? Do you see this error message when you're texting one particular short code, or all short codes? Is this your first time giving this a shot, or did this work for you previously and suddenly stop? ¡Gracias!

Hi, I am having the same issue. I do not know how to check if I have ever opted in to block particular services. All I know is that it stopped working one day, and now every time I try to text to a 5 digit number, I get a reply "Service access denied." Please help!

Thanks Marissa. I have a T-Mobile account. I have a J7 Samsung phone. It was working and it suddenly stopped.

All short messages stopped working.
