Cannot place call **826 in US

[4Siu1]

Wondering why cannot place ** 826 in US, even my plan is included US unlimited calling ?  Data roaming was turned on.

All USA area codes should be available. Some 1-800 might not.

is 826 an area code?

did you try out a 1 in front?

and can you make calls to other no number?  what phone do you have?
