what does code mean
"Connection problem or invalid MMI code" What causes this message and what does it mean. Presently phone show it's dialing and it never rings the number.
If you type in the wrong code on your phone for a particular characteristic (such as calling forwarding) you'll get an "Invalid MMI Code." It's also possible to get an "Invalid MMI Code" message after you've entered the correct information in the event that you're not subscribed to the feature or service by your service provider.
For instance, some carriers provide the ability to forward calls as a standard feature however, others require you to pay an additional fee to use the service. If your phone is compatible with making these codes, make sure that the data entered into this code matches and you're eligible to use the feature or service.
