  • You will make many calls on your own number and want them on the same bill.
  • Your phone is locked to your carrier (an eSIM needs an unlocked phone).
Inbox eSIM

Use a travel eSIM if

  • You are away for most of a week or longer.
  • You want one price you know before you fly.
  • You want your number to keep working while data runs on the eSIM.

A 10-day trip to Japan with normal use costs $9.90 with Inbox eSIM (10 GB, 30 days).

Can I keep my phone number with a travel eSIM?

Yes. The eSIM carries data only and sits beside your main SIM: calls and texts to your number still reach you on the main line, while data goes through the eSIM. Turn off data roaming on your main line so it does not charge a day pass by mistake.

When is Australia carriers the better choice?

For a day or two, when your plan already includes roaming, or when you need many calls on your own number. From about 2 days of data use, a travel eSIM usually costs less.

Do I need a new phone for an eSIM?

Most phones from 2019 on support eSIM; it must be unlocked by your carrier. Check yours on our compatibility page before you buy.

One price for the whole tripData only; your own number keeps working on your main SIM.
