Hey everyone,
I have a very strange, but entirely repeatable, problem when roaming with my EE plan in the US. I use a Google Pixel 7 Pro, but I remember experiencing this with a Pixel 6 Pro too back when I had that device.
Whenever I am Stateside, any calls that require touch tone / DTMF dialling to navigate an IVR (e.g., "for another twenty options you didn't ask for, press 1") do not work. I am currently roaming on AT&T, and it does not seem to make a difference whether I am on 4G or 5G. Sometimes my phone will drift over to T-Mobile (US), but this is usually only for a short while so I haven't had the chance to test this network yet.
Not only have I observed this, but I can actually reliably reproduce it using Twilio. I have a trial account with them, so any time I get a call I'll receive the warning message that I'm on a trial account, followed by a prompt to "press any key to run [my] code". No matter how many times I press any key (or which key I press), Twilio will time out and terminate the call. Calling my Skype number, on the other hand, will work just fine and I'll be able to run my code by pressing a key that way.
I have also observed this with Google's hardware support team. When you request a callback, you have to press a key to speak to a human; otherwise, you just get cut off. Again, no matter how many times I tried to do this, it wouldn't work and I had to use an alternative phone that is not roaming in the US.
It should go without saying, but I have no issues at all with DTMF / touch tone dialling when I am in the UK and no longer roaming, so there is definitely an issue here.
Any ideas on how to fix this? I saw in another post that some phones have the option for a longer tone, but I do not see that option on my Pixel. Also, I found a thread on Apple's forums in which an iOS user had the same problem, so this seems to be a network issue rather than a handset one.
Thanks in advance!
Chris
