Quick answer
Roaming happens when your phone connects to a network other than your home carrier's — typically when you're in an area your carrier doesn't directly cover, or when you're in another country. Your carrier pays a fee to the host network for the connection and may pass that cost to you.
Domestic roaming (within the US) is often included free on major plans, though terms vary by carrier and plan. International roaming varies significantly — many postpaid plans include Mexico and Canada at no extra charge, while others charge $5–$15 per day or per MB abroad. Always check your specific plan before you travel.

Domestic roaming vs. international roaming
Domestic Roaming — Usually Free
Happens when you're in the US but outside your carrier's direct coverage area — your phone picks up a signal from a partner network. For most major carriers and MVNOs, domestic roaming is included at no extra charge.
International Roaming — Check Your Plan
Happens when you leave the US and your phone connects to a carrier in another country. This is where costs can get significant — unless your plan specifically includes international coverage. Always verify before you travel.
Which carriers include Mexico and Canada free?
Mexico and Canada are the most common international destinations for US travelers. Here's how each carrier handles it:

| AT&T (eligible unlimited plans) | Included on many plans | MX/CA talk, text, and data on select unlimited tiers — not every AT&T plan qualifies. Check your plan's international features. |
| T-Mobile (eligible unlimited plans) | Included on many plans | North America benefits included on most unlimited plans; some pay-in-advance or no-credit-check plans may be excluded. |
| Visible+ / Visible+ Pro | Included | International benefit included — verify current plan terms, as Visible's international features have changed over time. |
| Visible (basic) | Limited or no data roaming | International benefits on the basic tier are limited — verify current plan terms before traveling. |
| Cricket (select plans) | Often included | MX/CA talk, text, and data on eligible plans — good North America value. Verify current plan terms. |
| Metro by T-Mobile | Usually limited | International roaming often requires add-ons; check current plan terms for MX/CA availability. |
| Mint Mobile | Typically add-on based | International access generally not included in base plans; international add-ons available separately. |
| Tello | Calling-focused | International calling features from the US; data roaming abroad is limited. Verify current plan terms. |

International roaming beyond Mexico and Canada
For travel outside North America, roaming costs and options vary widely by carrier:
International options by carrier type:
Verizon / T-Mobile / AT&T postpaid: Daily international passes ($5–$15/day) or international plans. T-Mobile Experience More includes 5GB high-speed data in 215+ countries. Verizon TravelPass is $10/day in 210+ countries.
Visible+ Global Pass: $10/day in 140+ countries (1 day/month included free on monthly plans) — one of the best value daily passes available on a prepaid plan.
US Mobile (Premium): 20GB of international data included with the plan — no extra charge for many destinations.
Best for frequent international travelers: Consider an international eSIM from a provider like Airalo or Holafly — often cheaper than carrier add-ons for extended trips. Use it alongside your US plan on a dual-SIM phone.

⚡ The Bottom Line
Roaming surprises are avoidable — just check before you travel.
Many major postpaid plans cover Mexico and Canada — but not all, and the details vary even within a carrier's own lineup. Budget carriers like Mint and Metro often don't include international roaming, which is a real trade-off if you travel frequently. If Mexico or Canada are regular destinations, verify your specific plan's international terms before you go. For occasional international travel, Wi-Fi calling and international eSIMs are often cheaper than carrier daily passes.
