Movistar México: pay-per-trip roaming
2026年9月時点Movistar doesn't include roaming in the US — it runs on traditional packages you pay for separately. The full list is on Movistar's international roaming.
| Option | Price | Includes |
|---|---|---|
| Daily Travel Pass (Travel Diario) | $70 MXN (≈ $4.08 USD)/day | “Unlimited” data, 60 min calls/day, unlimited texts |
| Bono 5GB USA | $199 MXN (≈ $11.59 USD) | 5GB data, valid 30 days, data-only |
| Travel Plus (small) | $549 MXN (≈ $31.96 USD) | 0.5GB, 30 min, 30 texts, valid 30 days |
| Travel Plus (large) | $1,099 MXN (≈ $63.98 USD) | 1GB, 60 min, 60 texts, valid 30 days |
| No package | — | $3 MXN/MB, $3 MXN/min — the rate that runs up your bill |
Movistar México was sold to Oxio in April 2026 and is transitioning to an MVNO model on AT&T México's network. The brand stays the same, but these prices can change — we recheck them before publishing and on every monthly update.
FairSIM eSIM: dedicated data for your trip
2026年9月時点With FairSIM, you get a data package separate from your Mexican plan, built just for your trip.
- 1GB / 7 days: $5.99 USD (≈ $103 MXN)
- 10GB / 30 days: $19.99 USD (≈ $343 MXN)
- Unlimited / 15 days: $44.99 USD (≈ $773 MXN) (1GB/day at full speed, then 1 Mbps)
Install it before you leave Mexico. When you land, you already have data — no hunting for airport WiFi, no waiting until you're physically in the US.
Activate it before you travel by following these steps — or check the full how eSIM works guide if it's your first time.
T-Mobile US Pass: the “buy it after you land” option
2026年9月時点| Duration | Price | Premium data (5G) | Hotspot |
|---|---|---|---|
| 7 days | $25.00 USD (≈ $429 MXN) | 50 GB | 14 GB |
| 10 days | $30.00 USD (≈ $515 MXN) | 50 GB | 20 GB |
| 14 days | $35.00 USD (≈ $601 MXN) | 50 GB | 28 GB |
T-Mobile US Pass includes unlimited calls and texts between the US, Mexico, and Canada, no ID or store visit needed. But here's the catch: per T-Mobile's own page, this plan can only be bought and activated once you're already in the US, on WiFi. You can't plan ahead for it — you land with no data until you find WiFi and finish activating, unlike FairSIM, which is already set up before you take off.
On paying with a Mexican card: T-Mobile says it accepts “domestic and international cards... from select countries” — we haven't confirmed Mexican cards are included, so don't assume it.
