Call Forwarding DTMF - T-mobile UK - General Topics

Hello,
I'd like to use speed dial to dial a DTMF from my Hermes that will turn call waiting on and off, but I don't know what the correct code is?
I've tried *20# but I get a unsupported error back.
Thanks

Anyone..........?

Dialing numbers starting with *

Hi
I'm using DVP and I have following issue.
in Poland to connect to voicemail you need to dial *501 or to business customer care *456
Unfortunately when I dial such numbers from my DVP I'm getting beep beep beep and the connection can not be established.
thanks in advance.

(Q) How to turn off call barring

Im using the t-mobile nexus s and I am in Vietnam right now and for some reason after placing a Vietnamese sim in and I try to call or text, it says: "You cannit make outgoing calls while call barring is on." Is there any way to turn off the call barring? I thought all the nexus phones are unlocked? Thanks! :fingers-crossed:

[Q] How to disable *90 call forwarding?

Hello I'm in Thailand and I have a True SIM card. To refill my credits, I'm required to dial a number starting with *90. But I'm unable to do this because it just brings up the call forwarding feature and so I'm unable to dial this number since the popup dialog interrupts the call. How can I disable *90?

Can not redial

I used my note 5 Verizon for AT&T service. When some people call me, I can't call back. It always dial 011 before the area code. Like if you call me from 1800xxxxxxx and when I call back it will be 011-1800xxxxxxxx. Any idea to remove. I already turn off assisted dial on the phone

At&t visual voicemail

I can't get visual voicemail to work on my phone. Talked to tech support and after an hour of trying to help me, they said this device is not supported by AT&T.
I tried setting up Google voice on this phone, but the phone won't let it forward calls. I just get an error.
Any help greatly appreciated.
What was tried for vvm?
Is it enabled in the dialer settings?
Not clear what the problem with GV is.
Try dialing *004*xxx-xxx-xxxx# (substituting your GV# for 'xxx-xxx-xxxx') to get calls forwarding to GV when your phone is busy or unanswered
When I use the *004*xxx-xxx-xxxx# I get "call forwarding connection problem or invalid MMI code. (1)"
When I try call forwarding through the phone app settings, I get "network or sim card error"
Reading online a new sim card won't fix this. I have reset network settings and rebooted. I've call ATT text support, but they have no answers and tell me this is an unsupported device.
So I can't get att visual voicemail to setup and because I can't use call forwarding, I can't use Google voice for their visual voicemail.
Any suggestions?

*004*xxxxxxxxxx*11#
That's the GSM code,works on AT&T and TMO, or at least did on my 3G phones.
Also seen **004*1xxxxxxxxxx# mentioned.
(Note 2 *s and the 1 before number

I tried both and get the same errors as before. You don't realize how much you miss a feature until it's gone. Standard voicemail sucks. Anyone else have a suggestion?
Maybe try 002 instead if 004?
(Though that forwards all calls. Could then deactivate with #21#)
Or the individual conditions using *67, 61, and 62.

They worked with TF AT&T when I last had GSM, in 2015.
Also saw some posts suggesting that AT&T won't allow changes to Cinditional Call Forwarding from the phone now and to call to have them set/change it.
With the March security update, AT&T visual voicemail now works.
