T-Mobile's Customer Initiated Port (CIP) app guides employees through transferring their phone numbers during enterprise device migrations, a process often complicated by timing constraints, device staging, and administrative oversight.


I led content strategy and UX writing for this initiative, which included:


Defining clear role boundaries between end users

and system administrators to prevent misdirected troubleshooting

Rewriting instructional flows to emphasize

device prerequisites and transfer timing dependencies

Restructuring error states to clarify when no

user action was required

Aligning micro-app language with Account Hub

dashboard logic to support a cohesive end-to-end experience

Validating resolution pathways with

Implementation Managers to reflect real-world porting workflows


This work reduced preventable transfer failures, minimized unnecessary administrative back-and-forth, and improved implementation efficiency during high-volume migrations.
