eSIM With a Phone Number: When You Need One

You need an eSIM with a phone number only if you must receive regular SMS or local calls. Most travelers do fine with a data-only eSIM, calling and texting over apps while keeping their home number active.

When a number matters

Choose a number plan for local SMS verification or business calls. Otherwise a cheaper data-only plan is enough. See data-only vs number eSIM.

Keep your home number

Either way, your home SIM stays active for your usual calls and texts.
