Hello, i want to change the shipping address of my new phone which is supposedly already on the way.

I’m in the same boat, they are about to ship to an incorrect address but they (T-mobile New-customer) won’t change it, and I cannot change it here because I have no phone number yet.

The order status page lets me put in an order number, but that order cannot be modified.

So yes, “I want to change the shipping address of my new phone which is supposedly about to be on the way”, and if T-Mobile won’t do it, It will get lost and I’ll be paying for nothing.
