AT&T International Day Pass vs a travel eSIM

$12.00 per line per day. AT&T charges $12 for each day you use the line abroad ($6 for each extra line on the account that day), and never more than 10 daily fees per line per bill period. Data: your domestic plan’s data. Source: AT&T, checked 5 Nov 2026.

For data, usually by a lot. Two weeks in Japan on International Day Pass is $120.00 a line; NUM’s 14-day Japan pick on 4 Nov 2026 was 5 GB for $4.79.

Yes. The eSIM carries your data; your AT&T line stays on your phone for calls and texts at home rates where your plan allows, or off while you travel. WhatsApp, iMessage and FaceTime work over the eSIM.

AT&T charges $12 for each day you use the line abroad ($6 for each extra line on the account that day), and never more than 10 daily fees per line per bill period. If you only need data, install a travel eSIM, set it as the data line, and turn off roaming on the AT&T line before you land.

Dial *#06# on the phone you’re taking. If you see an EID number, it takes an eSIM. Every iPhone from the XR and XS on does, and the SE from 2020, as do Google Pixel 3 and later and Samsung Galaxy S20 and later. The phone must be carrier-unlocked. Not sure? Text PHONE and your model and we’ll check.

At home, on wifi, before you fly. Then switch it on when you land. Tell us your landing day and we text you the switch-on steps that morning.
