Hello,

I would like to access the voice mail from direct access button of my iPhone5S. I am with TRUE MOVE 4G.

Do you know how I can do this ?

Thank you.

I think both iOS (Carrier Settings unique to TrueMove H) and TrueMove H's network must be able to support this feature. I guess you may have to check with them (TrueMove H) to see if this supported.

Otherwise just dial the access number, which I think is *99?

Do you get any kind of notification about a new voicemail left for you?

Voicemail isn't all that popular here; it is challenging to get a Thai person to leave one, and service providers all handle notifications and access a bit differently. Some here give notification, with a direct access cal-back link.
