Letter of Agency (LOA)
Whether you plan to port just a few numbers or all of them, your journey begins with the Letter of Agency (LOA), a critical document that allows you to retain your existing phone numbers while transitioning to SimSIP. Simply complete the attached form and return it to SimSIP to initiate the porting process.
Add-On Number Addendum
Are you planning to port more than 10 numbers at a time? No problem. We have the ideal solution for you. Accompanying the LOA form, this additional document is specifically designed to meet your high-volume porting needs. Feel free to use as many as required to include all the phone numbers you wish to port.
Toll-Free RespOrg Change
For those seeking to port toll-free numbers, we provide an authorization form for appointing a new RespOrg. This document helps facilitate a seamless transition. Please ensure you have the authorization to port these numbers from your provider.
Toll-Free Add-On Addendum
We also facilitate high-volume toll-free porting with an additional LOA-connected document. Similar to standard phone numbers, this document allows you to port toll-free numbers simultaneously. There is an addendum if more space is required.
