<p><a href="https://inboxesim.com/roaming-calculator">Roaming cost calculator</a> by Inbox eSIM</p>Questions
Is a travel eSIM cheaper than my carrier's roaming pass?
Usually, for trips of three days or more. Ten days in Japan cost $120.00 on AT&T International Day Pass and $7.79 with our 10 GB, 30 days pack (2 Nov 2026). A pass wins when your plan already includes roaming (for example T-Mobile Included in Experience More / Beyond, Go5G Plus / Next) or the trip is a day or two.
Do I keep my phone number with a data eSIM?
Yes. A travel eSIM adds data only. Your home line stays on for calls and texts (your carrier may charge roaming for those), and WhatsApp, iMessage and FaceTime run over the eSIM's data.
How does the calculator count the cost?
A day pass is counted for every day of the trip; a pass that covers several days is bought as often as the trip needs. Our side is the cheapest single pack that lasts the whole trip with at least the data you picked, or a Day Pass of the same length.
