Is this being done during initial activation of after account setup. During activation, number porting can be done during the number selection step. The options are choose number or port number. If porting, there is an eligibility check done first. After the check, additional information on the old account is required to support the number port. After all the activation steps are completed, the number port is initiated.
For porting into an existing account, simply go into the self serve portal and select the change number option. Everything from there is identical to porting during activation.
If bugs are encountered during the process, try using a different browser. Chrome is suggested.
