# eSIM and one-time codes

A phone number is where most mobile automation stops: the code arrives somewhere the agent cannot read. A mobilerun phone can carry a real eSIM whose number is reachable over the API, so the agent reads its own login code and the run continues.

- Bring your own eSIM: install your carrier profile over the API, self-serve, on a device that supports it.
- Or request an agent SIM from mobilerun, provisioned per country as part of a custom setup.
- Several subscriptions can sit on one device, with the active one switched between tasks.

This covers anything that verifies by phone number: two-factor prompts, WhatsApp and Telegram registration, banking and delivery apps.
