Answered October 2026

You can keep your Canadian number on Public Mobile or transfer it to Quo's internet phone service; get a separate US number if you also want a US cellular line.

“I recently moved to the US from Canada and have a US/Canada/Mexico plan with PublicMobile. Can I find a US service provider that lets me keep my current Canadian number, or do I need to start fresh with a new US number?”

Summary

You do not have to discard a number people already know. The important distinction is that keeping a Canadian number and getting a US cellular number are separate decisions.

You can keep the Canadian number; the choice is whether it stays on Public Mobile, moves to an internet phone service, or stays alongside a new US cell number.

Keep Public Mobileleast change

Keep your existing Canadian number and CAN–US–MEX subscription. Public Mobile says the subscription works in the United States and that US use is not subject to a fixed number of days, although its guidance does not expressly address permanent US residence. [Public Mobile](https://www.publicmobile.ca/en/get-help/articles/mex-subscription).

Move the Canadian number to Quokeep number

Quo says it accepts local Canadian numbers from traditional carriers. You can ask it to your Public Mobile number, but Quo turns it into a number used over Wi-Fi or mobile data—not a US cellular line. Keep Public Mobile active until the transfer finishes. [Quo](https://www.quo.com/porting); [transfer instructions](https://support.quo.com/getting-started/porting/overview).

Add a US cell numbertwo numbers

Keep Public Mobile for your Canadian number and start a separate US line if you need a US number or US cellular service. For example, T-Mobile allows an unlocked, compatible phone to activate a prepaid online and assigns a new number; a compatible dual-SIM phone can use two lines. [T-Mobile](https://www.t-mobile.com/support/account/prepaid-esim-activation); [Apple](https://support.apple.com/en-us/109317).

A Canadian number transferred to an internet phone service does not become a US number or a conventional US cellular line.

Watch out for

Do not cancel Public Mobile before a transferIf you transfer your Canadian number, keep Public Mobile active until the transfer finishes. Canada's telecom regulator warns against canceling first, and Quo says your old SIM and cellular service will be deactivated after the transfer. [CRTC](https://crtc.gc.ca/eng/phone/mobile/num.htm); [Quo](https://support.quo.com/getting-started/porting/overview).
Watch for the approval textFor a Canadian mobile-number transfer to Quo, your current carrier sends an approval text. You have 90 minutes after it arrives to respond; missing that window cancels the request. Keep the Public Mobile line able to receive texts while the transfer is pending. [Quo](https://support.quo.com/getting-started/porting/overview).
An internet number is not a cell lineMoving your number to Quo changes it to an internet-based line. Quo says some verification texts will not arrive and its numbers do not provide 911 calling. Keep or obtain a cellular line if you need those functions. [Quo porting](https://www.quo.com/porting); [Quo messaging](https://support.quo.com/troubleshooting/messaging-issues).
The 15-day rule is for a different productPublic Mobile says roaming add-ons last 15 days, but separately says use of its CAN–US–MEX subscription in the US and Mexico is not limited to a certain number of days. Do not mistake the add-on deadline for a deadline on the subscription you described.

Next steps

Choose the service you need first, then follow only the steps for that route while protecting your existing number.

Before changing providers

Keep your Public Mobile line active

If its service meets your needs, no number transfer is required: Public Mobile says this subscription works in the US without a fixed limit on days of US use. If you intend to transfer the number instead, do not cancel Public Mobile beforehand. https://www.publicmobile.ca/en/get-help/articles/mex-subscription; https://crtc.gc.ca/eng/phone/mobile/num.htm.

In Quo, go to Settings → Phone numbers → Port an existing number → Continue to porting; select Public Mobile or type its name, enter the requested account and billing details, and sign the authorization. Quo says the transfer itself is free; its Starter monthly subscription is listed at $19 per user per month.
