If you are keeping T-Mobile while moving into Previ’s account arrangement, coordinate a Change of Responsibility with Previ first. The current account owner must authorize the change using the receiving details Previ confirms.
Confirm the route with Previ
A change of responsibility changes account ownership for an existing T-Mobile line. It is different from a transfer PIN used to leave the network. Tell Previ the numbers you want to bring and whether the current account is personal or business. Ask which approval process and receiving details apply.
Have the current owner authorize the change
T-Mobile requires the current account owner’s authorization. Its consumer/postpaid guidance involves both the current and receiving owners contacting T-Mobile. Transfers involving a business line have a separate process. Follow the route Previ confirms for your account rather than initiating an unrelated consumer transfer.
Resolve connected account details
Before approving the handoff, confirm how device installments and any lines staying behind will be handled. T-Mobile’s general ownership-transfer guidance does not establish that Previ accepts every balance, promotion, or account type.
Check that the receiving step is complete
After the owner’s authorization, follow up with Previ to confirm acceptance of the intended numbers. Check that service works on those lines. If only part of the household moved, identify the outstanding number when you contact support.

Here’s how to authorize a T-Mobile account-responsibility transfer to Previ.
A T-Mobile change of responsibility changes ownership of an existing line. It is different from a transfer PIN used to leave the network. Tell Previ the numbers and whether the current account is personal or business, then ask which approval route applies.
The current account owner must authorize the change. T-Mobile’s consumer guidance involves both current and receiving owners; business lines follow a separate process. Follow the route Previ confirms for your account.
Confirm how device installments and lines staying behind will be handled before approval. T-Mobile’s general instructions do not mean every balance, promotion, or account type is accepted by Previ.
After authorization, confirm with Previ that the intended numbers were accepted. Check calls and messages on those lines. If only part of the household moved, identify the outstanding number when contacting support.
Use the steps for your own line and device. If the screen or result is different, contact Previ support with the message you see.
