will pay for it on Friday 6 2018
Hey there ritabryte! Congrats on the move! You may have a few options -- a Payment arrangement would be helpful if you only want to make a temporary change to your due date, for this current bill. If you'd like to permanently Change your billing cycle & due date then that's a little more complex, and you would need to be ready for a prorated bill while the billing cycle itself changes (that's what dictates when your bill is due).
If you just need to set up a payment arrangement, then the button on that first page I linked to should take you to MyTMobile and you should be able to set it up from there without a fee! If you were thinking about a bill cycle change though, we'd need to have you Contact Us.
