To initiate the transfer, please commission **your new provider**, who will initiate everything required. #### Take landline numbers with you The porting of landline numbers is **free of charge**free of charge. For landline numbers, a maximum of 10 individual numbers or one number block can be ported per order. When porting mobile numbers, there are **also no costs**. However, only one mobile number can be ported per order. #### Port mobile numbers One of your employees wants to leave the company, but would like to keep the mobile number they have been using? No problem, at sipgate you can also port mobile numbers to another provider. To do this, you need to **release the number for porting**. You can only grant this release as **administrator** . It is valid for a period of **30 days**. **Here’s how it works:** As an admin, go to your sipgate **account management**. There, select the navigation item **Phone numbers** from the list of your account-wide numbers, navigate to the mobile number that you want to release for porting to another provider. You also have the option to release a single mobile number from a block of mobile numbers or even the entire block for porting. To do this, click the button with the three dots (context menu) to the right of the list entry and select **Release for porting** Now the porting process can be started with a new provider. Various details will be requested there. {% hint style="warning" %} **Important**: To ensure porting succeeds smoothly, the details entered must be identical to the sipgate data. These details are: * mobile phone number * Number holder: your full company name * Provider: sipgate (sometimes also sipgate Wireless or Vintage Wireless) * Contract type: business * Porting date: as soon as possible * sipgate customer number (seven digits) {% endhint %} --- # Agent Instructions This documentation is published with GitBook.
