[takeaways] • An eSIM is a digital SIM chip built into your device — no physical card to insert, swap, or lose. You activate it by scanning a QR code, and it's ready in minutes.
• Most travel eSIMs are data-only. For calls and messages, use WhatsApp, iMessage, or similar apps over your data connection. Your physical SIM can stay in your phone simultaneously for your regular number.
• iPhone XR and newer, Samsung Galaxy S20 and newer, and most flagship Android devices from 2020 onwards support eSIM. Dial *#06# on your handset — if an EID number appears, your phone is eSIM-compatible.
• If your phone is lost or stolen, your eSIM can be remotely deactivated by your provider and transferred to a replacement device once you have one.
• A SIMOVO eSIM installs before you travel and activates the moment you land — no hunting for local SIM cards, no roaming charges, no physical card required. [/takeaways]
An eSIM (embedded SIM) is a digital SIM card built directly into your phone as a chip. Unlike a traditional SIM, there's nothing to insert or swap — you activate it through software by scanning a QR code, and it works like any other SIM card: giving you access to mobile data, and on supported plans, calls and texts.
This guide covers everything worth knowing before you get started.
What is an eSIM and how does it work?
A traditional SIM card is a small physical chip you insert into your phone. An eSIM is the same technology, built permanently into the device. The functionality is identical — connecting you to a mobile network — but managed entirely through software rather than a physical card.
Most modern phones can store multiple eSIM profiles, allowing you to switch between networks or plans without touching any hardware. For travelers, this means purchasing a travel eSIM online before you fly and activating it in minutes — no hunting for local SIM kiosks on arrival.
How calls and texts work with a travel eSIM
Most travel eSIMs — including SIMOVO — are data-only. They don't provide a traditional phone number for calls or SMS.
For calls and messages, use data-based apps: WhatsApp, iMessage, FaceTime, Telegram, or Facebook Messenger. These work over any active data connection and let you communicate with family and friends at no additional cost beyond your data plan.
If you need your regular number to remain reachable for incoming calls and texts, keep your physical SIM in your phone alongside the SIMOVO eSIM. Your home SIM handles voice and SMS; your eSIM handles data. This dual setup is how most frequent travelers use eSIMs — full connectivity on both fronts, with no roaming charges on the data side.
eSIM vs traditional SIM — the key differences
- Location — A physical SIM is a removable chip. An eSIM is permanently embedded in the device and managed via software.
- Convenience — Changing providers or plans on an eSIM is done entirely digitally, with no physical card to source, insert, or return.
- Durability — An eSIM cannot be damaged, lost, or misplaced. Physical SIMs can be all three.
- Device compatibility — eSIMs require a phone with built-in support. US versions of the iPhone 14 and later have no physical SIM slot at all and are eSIM-only.
Why use an eSIM?
- Instant activation — Purchase online and activate in minutes. No waiting for a physical card to arrive.
- No roaming charges — A prepaid travel eSIM gives you local data rates instead of your home carrier's international roaming fees.
- Multi-country coverage — Regional and global eSIM plans cover multiple countries on a single purchase, with no swapping required at borders.
- Dual SIM — Run a travel eSIM for data alongside your regular SIM for calls and texts — both active simultaneously on the same device.
- Eco-friendly — No plastic card produced, packaged, or discarded. Every eSIM purchase removes one more physical SIM from the waste stream.
Which devices support eSIM?
- iPhone — iPhone XR and all models released after it.
- Samsung Galaxy — S20 series and newer.
- Google Pixel — Pixel 4 and newer.
- Other devices — Many Android flagships from 2020 onwards, plus selected tablets, laptops, and smartwatches.

If an EID (Embedded Identity Document) serial number appears alongside your IMEI, your phone supports eSIM. If you only see an IMEI, the device does not support eSIM.

How to activate a SIMOVO eSIM
After purchasing a SIMOVO plan, you'll receive an email with a QR code and activation instructions. The process takes under five minutes.

If you're keeping your physical SIM active for calls, set data roaming to off on that line to prevent your home carrier from connecting to foreign networks in the background.[/tip]
What if your phone is lost or stolen?
An eSIM can be remotely deactivated by your provider — contact SIMOVO as soon as possible if your device goes missing. This prevents unauthorized use of your data plan and secures your account.
In most cases, your eSIM plan can be transferred to a replacement device once you have one. As always, enable Find My iPhone (iOS) or Google Find My Device (Android) on your device as an additional safeguard.
Staying in touch using data-based apps
Because SIMOVO eSIMs are data-only, you won't receive a separate phone number. For calls and messages abroad, use any of the following over your data connection:
- WhatsApp — Calls, messages, video calls, and file sharing. Stays linked to your regular number.
- iMessage and FaceTime — Works between Apple devices over data. Linked to your Apple ID and regular number.
- Telegram — Messaging and calls, with a focus on privacy.
- Facebook Messenger — Messaging and video calls linked to your Facebook account.
Your regular SIM stays active alongside the SIMOVO eSIM for incoming calls and texts to your normal number — so nothing changes for people trying to reach you.
