eSIMs are among the most beneficial yet frequently perplexing tools available to travelers. We’ve [discussed eSIMs](https://foxnomad.com/2020/02/20/what-are-esims-easy-mobile-internet-for-travel/) previously, and the video above covers all the primary queries many of you posed. Watch [it here first](https://youtu.be/frluSjMwgyw?si=7rOhCF_MZucpt6RR) before exploring the quick responses below.
**Do You Receive A Phone Number?**
This is contingent upon the [eSIM service provider](https://foxnomad.com/2023/12/21/how-to-use-esims-when-traveling/) in your locale, rather than the eSIM technology itself. For travel eSIMs, the typical response is no, as most online retailers like Airalo, BNEsim, and Holyfly lack the necessary licenses for phone numbers (and SMS), hence they supply only data.
**Is SMS the Same?**
Yes, that’s accurate.
**How Can I Make Calls?**
You can utilize Facetime, Whatsapp, Signal, or any other [Internet-based calling platform](https://foxnomad.com/2016/11/10/5-reasons-use-airplane-mode-even-youre-not-flying/). Otherwise, making a call with the travel eSIM is not feasible if it doesn’t include a phone number. You may visit a local store or airport kiosk and establish a temporary mobile account (which will likely still involve an eSIM) but usually obtain a phone number instead of just data. Alternatively, you can activate your home mobile service to offer international roaming for use during travel.
**Is It Possible To Use Multiple eSIMs Simultaneously?**
Nearly all phones equipped for eSIMs allow you to use two eSIMs concurrently. (You can install many more.) This enables you to use your home eSIM/service for calls and the local eSIM for data. Just ensure that you’re utilizing the appropriate eSIM for both. To be cautious, deactivate your home eSIM when it’s not in operation.
**What Occurs With Your Home eSIM?**
Nothing at all. Any new eSIMs operate independently, much like physical SIM cards would.
**eSIM Conclusion**
In essence, eSIMs can significantly simplify staying connected while traveling. They can be obtained ahead of time and activated later if necessary, providing you data worldwide. There are also regional eSIMs, all available for purchase directly from your phone.
