  4. Submission to Carrier
    CloudTalk submits your request to our partner carrier, who then forwards it to your current provider.

Issue

What It Means

How to Fix It

Mismatched address

Ask your provider whether the range can be split

Inactive number

Ask the provider to reactivate the number before porting

Outdated invoice

Provide a more recent invoice from your current carrier


On Porting Day
