11 Best International Roaming Plans Compared for 2025

3. AT&T international plans (International Day Pass / Passport)

AT&T offers both a day‑pass style option and dedicated international bundles, giving travelers flexibility. The International Day Pass typically charges a flat daily fee for using your domestic plan abroad in supported countries; it’s handy for short trips because you keep your usual minutes and texts and pay only for travel days. Passport-style packages provide data allowances or pay‑as‑you‑go rates in selected countries and may be cheaper for longer stays with predictable usage. Activation requires adding the pass or bundle through your AT&T account before departure and ensuring your device is unlocked and compatible. For Indian-origin travellers visiting North America, a Day Pass can avoid surprise bills during a short family visit. The downside is that daily fees add up on multi-week trips, and the pass may not include full-speed data in every country. Pros: simple pricing for short trips, retains your number. Cons: not always the cheapest for extended stays. Best for: short business trips or family visits where convenience beats absolute savings.
