I can help you setup your payment arrangement here but I also want you to save paying the added $10.00 Payment support fee if we do it from here.
This is best recommended to be setup thru your T-Mobile APP or My T-Mobile.com from any web browser following these quick and easy steps :
-Open the app and tap BILL. -Tap Set up a Payment Arrangement. -Tap Continue and view the Amount -Tap Payment Method. Previously stored payment method will show, if available. -Tap Continue, read the Terms & Conditions and tap Agree & Submit. -Review the confirmation screen and tap Continue.
