Yesterday I was install "line"
This app are like “Whatsapp”, it require to input my phone number and sent activate SMS to me.
But after I enter my telephone number I didn’t received activate SMS.
Today I call to my provider and confirm “Can I receive SMS from other countries”.
The answer is “Yes, I can I receive SMS from other countries”, however they need me to use “#35*0000# and call” to force it again.
But after I use “#35*0000# and call” I got error message “Call barring Connection problem or invalid MMI code”.
Is this problem occur by my Atrix or provider?
If it occur from my atrix how I solve it?
Thank you
I've assigned a contact to #2 on speed dial but when i try it I get 'connection problem or invalid MMI code'
My contacts are saved on the phone's memory. I'm not sure what I can do to fix this problem. I am running Wanamlite ICS XXLPD11.6
I'm trying to set up my voice mail inbox but when I do I get the error 'Connection problem or invalid MMI code'.
I've had the phone for about a month & a half now. I recently factory reset & rooted it within the last week. I hadn't set up my inbox prior to the root, I'm not sure if it worked before the root.
Any ideas on how to fix this? I don't want to take my phone into AT&T for them to fix it w/ a root. (Unless I am allowed to do this).
Update*
Called AT&T & they said it was an error on their end. Unfortunately we weren't able to resolve the problem. They opened a support ticket and said they'd contact me back within 5 business days.
I have an issue with Call forwarding issue with T-MO V10 Unlocked on ATT Network.
I went ahead and follow the steps where it was posted on ATT website,
Go to Settings->Calls->Call Forwarding
Select Always Forward and enter Tel#.
When I did that, I get "Call settings error - Unexpected response from network."
So, I tried *21*TelNumber#, then I get "Call Forwarding - Connection problem or Invalid MMI Code."
AND I also tried **21*TelNumber#, same error message, "Call Forwarding - Connection problem or Invalid MMI Code."
Is anyone having an issue like this setting up as far as setting up Call forwarding on ATT network with T-MO Unlocked V10???
Thanks in advance!
I have the Mate 10 Pro US version. I'm on the AT&T network. Anyone have any problems setting up call forwarding on this phone? I get a "Connection problem. Invalid MMI code." error everytime I try to turn it on using **21*(phone number) #. If I do it through the phone app settings nothing happens. I didn't have this issue with my old phone. Can anyone else try it out and let me know? Thanks!
