How You Can Keep Your US Number While Abroad

Practical options and the exact steps to receive calls to your US number from anywhere in the world.

Keep Your Carrier SIM

Leave your US SIM active and enable roaming with your carrier. This keeps the number live but may require carrier setup. Use StartACall in the browser to place calls over Wi Fi while traveling.

Call Forward to a Virtual Number

Set conditional or unconditional forwarding to a US virtual number. With StartACall you can buy a US virtual number and receive forwarded calls in your browser instantly.

Port Your Number to the Cloud

Porting moves your number from a mobile carrier to a cloud provider. Once ported, your number lives in the cloud and rings to StartACall so you can answer from any browser without the physical SIM.

Buy a US virtual number or start the porting process to move your existing number.
