Frequently Asked Questions

Common questions about business number porting answered.

Can I port multiple business numbers at the same time?

Yes. You can port your entire business fleet simultaneously. Simply request a PAC code from each line by texting PAC to 65075, then provide all codes to our business team. We will coordinate the transfers so all numbers move together on your chosen date.

Will my business experience any downtime during the transfer?

There is a brief transition window, typically lasting only a few minutes, where incoming calls may route to voicemail. Most businesses find this barely noticeable. We recommend scheduling transfers during quieter periods if call continuity is critical.

What happens to my existing contracts with my old provider?

Once the port completes, your old contract is automatically cancelled for the ported lines. If you are within a minimum term, an early termination fee may apply from your old provider. Check your contract terms before requesting PAC codes. TISA itself charges nothing for the port.

Do you support eSIM for business number porting?

Absolutely. You can port your existing business numbers directly onto eSIM compatible devices. This means no waiting for physical SIM delivery and instant deployment for your team. Contact our business team to arrange eSIM porting for your fleet.
