Step-by-Step Porting Process

You send us the LOA + latest invoice.
We forward your request to our carrier partner.
The carrier submits the request to your current provider.
Once approved, we’ll confirm your port date (usually 2–4 days in advance).
If rejected, we’ll guide you in resolving the issue and resubmitting.
Common Rejection Reasons
Avoid delays by checking for:
Incorrect or mismatched information - Name and address must match your provider’s records exactly.
Outdated or incomplete invoice - Submit a recent invoice with clear ownership details.
Unsigned or incorrectly signed LOA - LOA must be signed by the account owner or an authorized person.
What to Expect on Port Day
Your number will switch to CloudTalk on the scheduled date.
Your previous provider will deactivate the number.
CloudTalk billing will begin the same day.
We recommend contacting your old provider to confirm the number has been removed from your billing.
