Why this rule existsrationale

Migration carries a brand's verified status across, and on this tier that status is a verification of a person that the receiving CSP did not perform — so the path simply does not exist. Anyone changing provider has to re-register and answer a fresh OTP, which is survivable if it is planned and disruptive if it is discovered during the switch.

How to fix itremediation

Plan a provider change as a new registration: a new brand, a new campaign, and a fresh verification text to the same handset. Keep the old brand running until the new one is verified, and expect the number reuse to count against the three-registration limit.

Check this yourselfattestation

Ekas flags this from what you submit, but the fact that settles it sits somewhere only you can reach.

If you are changing provider, have you planned this as a fresh registration rather than a transfer?

1Confirm there is no migration path for this tier — there is not — and plan a new brand, a new campaign and a fresh OTP to the same handset.
2Stand the new brand up before retiring the old one, and count the number reuse against the three-registration limit.

What wrong looks like: The switch is planned as a migration, the request is refused at the registry mid-move, and there is no transfer to fall back on while the new registration stalls.

Notesnotes

The migration is refused at the registry, not by us. What the user has to do is sequence the change themselves — stand the new brand up before retiring the old one — because there is no transfer to fall back on if the new registration stalls.
