AT&T phone roaming and iPhone unlocking guidelines for Canada travelers

AT&T smartphones can connect to Canadian networks such as Bell, Rogers and Telus under existing roaming agreements, allowing calls, texts and data north of the border. Compatibility depends on the subscriber’s plan; older or basic plans may require an added international roaming package or the International Day Pass, which incurs per‑minute and per‑megabyte charges. Customers are advised to verify their plan details online or by contacting AT&T before traveling.

For users who wish to use an AT&T‑locked iPhone on any carrier, AT&T requires that the device meet eligibility criteria and that the owner submit an unlock request through the official AT&T unlock portal. The process involves providing the iPhone’s IMEI number and account information, after which AT&T typically approves the request within a few business days and sends instructions to complete the unlock, often by inserting a non‑AT&T SIM card or updating the activation policy over Wi‑Fi.
