Call MMI code from iOS Shortcut - MMI or SSD is not supported

Call-MMI-code-from-iOS-shortcut.md

When trying to create an iOS Shortcut which calls an MMI code, such as the forwarding interrogation code *#21#, you may find that Shortcuts refuses to place the call and shows the error message MMI or SSD is not supported.

You can work around this in some circumstances by opening a tel: URL to the MMI code. To do so:

1. Create an action to "Open URLs"
2. For the URL, enter tel: followed by the MMI code you want to dial, replacing * (asterisk) with %2a and # (pound sign) with %23

To dial *#21#, your shortcut action would say the following:

Open tel:%2a%2321%23

Failing to percent-encoded * and # will result in another error saying Open URLs failed because Shortcuts couldn't convert from Rich text to URL.

The result of this is that when the shortcut is executed, you'll see a button pop up on the bottom of the screen asking if you want to call *#21#. Clicking on this button will place the call successfully.

Thanks!

Hi! Thanks for this! Very helpful! Any chance I could avoid dealing with that pop up? I would like for my code to be executed without the system prompting me to confirm. Thank you!

A similar solution is:

1. Add a Phone Number action.
2. Add your USSD code as the Phone Number.
3. Create an Open URLs action after that (it should automatically use Phone Number as a URL or you can add it yourself).

This would also yield the same result.

It's not working on my phone, which ios version is 16.3
When then shortcuts run, the result is "mmi or ssd is not supported"

I tried a lot, finally got a solution.

1. Edit a safari bookmark, type then encoded url. For example: %2a3939
2. Add a Open Bookmark action, select the bookmark we edited.

Hallo,

First, thx for this solution. But i cant get it ready to work without the URL Popup. Last Example with Open Bookmark is not working for me and get the same result. Maybe i do it wrong but i cant find the issue.
