What is an eSIM?
An eSIM (Embedded SIM) is a digital SIM built into your device. It lets you switch mobile providers and activate data plans without a physical SIM card. You can download and install plans online.

What’s better: eSIM or regular SIM?
eSIM is more convenient. You can activate data plans instantly without waiting for a physical card. You can also store multiple profiles and switch easily — great for travelers.

Does an eSIM include calls?
Usually not. Most providers offer data-only eSIMs.
You can use it for internet while keeping your regular SIM active for calls and texts, but that may result in extra charges.
For calls, use apps like WhatsApp, Zoom, Telegram, or Google Voice.

Does eSIM replace my regular SIM?
Not necessarily. You can use both at the same time — keep your regular number active and use the eSIM for data abroad.

How do I know if my phone supports eSIM?
Check in your settings:

• iPhone: Settings > General > About > Look for “eSIM Available”

• Samsung: Settings > Connections > SIM Manager > Check for eSIM option

• Google Pixel: Settings > Network & Internet > SIMs & eSIM

You can also find a full list of supported devices later in this guide.
Always check the eSIM provider’s site before buying.

Is there a difference in speed between eSIM plans?
Speed depends on the local network (4G or 5G), coverage in your area, and plan terms.
Most providers work with major local networks, but check coverage in the areas you’ll visit.
For faster internet, look for plans with 5G support.

How do I get the discount you offer?
Most links on our site include a built-in discount. Just click through our links to get the best available price.

How do I activate the eSIM after purchase?
After buying, you’ll get a QR code or link.
Scan the code under your phone’s cellular settings and set it as your active line.
Then, confirm you’re connected to the right network and start using it.

When should I buy the eSIM?
Buy it before your trip. Install it at home so it’s ready to go — it will only activate on your travel date or arrival.
Use your home Wi-Fi to install any apps or offline maps you’ll need to save data abroad.

What if I run out of data?
You can always buy another plan from the same provider or check our site for deals with other providers.

Can one eSIM be used for the whole family?
It’s better if each traveler has their own eSIM. That way, you can stay in touch and help each other if someone runs out of data.
Share this guide with your travel group to get the best deals.

Who can I contact if I have eSIM issues?
Most major providers offer 24/7 support and can help with setup or troubleshooting.
