Fair use

Packs have a GB amount and a day count. When either runs out, Inbox eSIM data stops. In many countries there is also a Day Pass: 3 GB a day at full speed, then 1 Mbps until the allowance resets, for the days you pick. We never call it unlimited, and that is its only cap. If a wholesale pack lists its own fair-use note, the country page shows Fair use.

Fixed GB packs

Packs run from 1 to 50 GB. Most last 30 days; the 1 GB pack lasts 7. There is no hidden daily bucket: the GB and the days on the fare are the limit. Compare.

Day Pass: the cap, said plainly

Where the country page shows a Day Pass, you pick the days. Each day the first 3 GB run at full speed; after that the line stays on at 1 Mbps until the allowance resets, about every 24 hours. 1 Mbps still runs maps, messages and mail, and video calls in low quality. Hotspot works and counts toward the 3 GB. We do not call this unlimited, because it is not, and there is no other cap.

A few Day Passes are routed through Hong Kong; the country page says so. Some local sites and apps may then treat you as abroad.

When a pack names fair use

Some packs carry a fair-use sentence from the network. That text appears on the country page as Fair use. If the strip has no Fair use line, the limit is the GB and the days on the fare.
