Frequently Asked Questions About eSIM

What is the difference between eSIM and a physical SIM card?

An eSIM is a digital SIM embedded in your phone — no plastic card needed. You activate it by scanning a QR code instead of swapping cards. It works alongside your existing SIM, so you keep your number while using local data abroad. eSIMs are faster to set up, impossible to lose, and more environmentally friendly.

Is eSIM cheaper than international roaming?

Yes, significantly. International roaming can cost $5–15 per MB, while eSIM plans start from $2.99 for 1GB. A week of data in Japan costs roughly $4–8 with an eSIM versus $50+ with roaming. eSIM plans are prepaid with no surprise charges.

Can I use eSIM and my regular SIM at the same time?

Yes. Most modern phones support Dual SIM — your physical SIM handles calls and texts with your home number, while the eSIM provides local data at your destination. Both lines stay active simultaneously.

How long does it take to activate an eSIM?

Installation takes under 2 minutes. Scan the QR code, confirm the plan, and the eSIM is ready. Data starts when you arrive at your destination and connect to a local network — so you can install days before your trip.

What happens if I run out of data?

You can purchase a top-up plan from your MyeSIM account at any time. Your eSIM stays installed — just add more data when needed. No need to scan a new QR code.

Can I share my eSIM data via hotspot or tethering?

Yes, most eSIM data plans support hotspot and tethering. You can share your mobile data connection with laptops, tablets, and other devices just like you would with a regular SIM card. Some plans may have fair-use limits on tethering, but the vast majority work without restrictions.

Do I need to unlock my phone to use an eSIM?

No, you do not need a carrier unlock to use an eSIM. eSIM profiles are independent of your physical SIM slot, so even carrier-locked phones can typically add eSIM data plans. However, a small number of carriers may disable eSIM functionality on locked devices — check your device settings for an "Add eSIM" option to confirm.

Can I get a refund if the eSIM does not work?

Yes. If your eSIM could not be issued, the order page gives you a one-click full refund. In every other case — including an eSIM that was sent to you but never installed — email support@my-esim.vip with your order ID and we will refund it as long as the plan has not been used. Refunds are typically processed within 3–5 business days.

Does an eSIM support voice calls and SMS?

Most travel eSIM plans are data-only, which is ideal for using apps like WhatsApp, FaceTime, and Zoom for calls. Some plans do include local voice minutes and SMS — these are clearly marked on the plan details page. Your existing physical SIM remains active for calls and texts on your home number.

How many eSIMs can I install on my phone?

Most modern smartphones can store 8 to 10 eSIM profiles simultaneously, though only one or two can be active at a time. This means you can pre-install eSIMs for multiple upcoming trips and simply switch between them in your device settings without needing to scan new QR codes.
