I try to use AccuDial Free V8.4.2 on HTC HERO and I keep getting the following error message: "Connection problem or invalid MMI code" whenever trying to dial a dial plan which is not just numbers.
Does anyone know how to solve this problem?
Thanks
I'm having the same problem
I'm having the same problem on my HTC vogue. Can anyone help? I am only able to make calls to one of my contacts it's very strange. All other contacts I get the error, connection problem or invalid MMI code. I am running Android 2.2.1 Kernel 2.6.32.9. Baseband: unknown
Thank you so much.
ok dont know if it will work for you but it worked for me
add comma (,) in the end of the code
example:
*100*2# into *100*2#,
works for me

Hey yall.. I have an SIP number that I have connected to SIPdroid and it works.
My issue comes up when I try to connect that number to Google Voice.
I get the confirmation call so they can see that the phone belongs to me, but when I type in the 2 digit code it says that it isnt working. not that the code is wrong, but that she didn't understand (or something) I used my N1 and then tried it on my cliq thinking the physical keyboard would help but it didn't
Hi to everyone..
Am having a weird problem.. i can't use speed dial.. there is message about a ussd code - connection problem or invalid mmi code...
do you know how to fix it??
this problem began from the first time i used the phone...
thank you..
I'm on Carbon ROM 7/27 build, though issue seems not to be version based. AT&T is my carrier.
I can receive SMS but not send. A clean install of my ROM fixed this issue, but within a few hours the problem re-emerged. Some Googling suggested I have a bad SMSC code. However, when I tried to initiate the fix through the dialer, I got a message saying "connection problem or invalid mmi code."
If you can help me fix this I would greatly appreciate it!

Hi,
I'm using Xperia Z1 purchased in India currently using in brazil.
I face a very annoying issue whenever I try to call any number with the state code and country code '014' gets added automatically to the number and the call does't connect. I looked at the settings there are no such options to block this. This issue doesn't happen when I call local numbers without the state/country code.
For example when i dial +55-61-12345678 it changes automatically to 014-61-12345678 and it says that number does not exist. I face this problem even when I dial 0055 instead of +55, it also exists for all the country codes. I also tried a complete factory re-set but this problem still persists. If anyone could help me it would be great.
Thanks in advance

This could be an issue from your SIM. 014 is one of Oi's long distance codes; Oi has a setting (on the SIM menu) to add its long distance code to any number you dial. So, it is intercepting the call and changing it to use Oi's code. Your best bet would be to enter the SIM menu and try to disable that option, and add the operator code manually to any number you dial.
My HTC One phone is coming up with different sorts of errors. Never been rooted or anything and a factory reset has not helped either. It was working fine previously.
Now when i try to dial out i get the error message:
Connection problem or invalid MMI code.
I also notice that it says USSD code running when i dial a number at times.
There is also a small message that says out of service area when trying to dial numbers.
