1. Introduction
With international travel, remote work, and global business on the rise, the need for seamless connectivity has never been greater. One of the most efficient and cost-effective ways to stay connected abroad is by using an eSIM (embedded SIM). But before you can take full advantage of an international eSIM, you need to ensure your phone is unlocked.
This guide walks you through the process of unlocking your phone, setting up an international eSIM, and troubleshooting common issues. Whether you’re a digital nomad, business traveler, or global communicator, this step-by-step breakdown will help you stay connected worldwide.
2. What Does It Mean to Unlock a Phone?
A locked phone is tied to a specific carrier or network provider, preventing you from using SIM cards or eSIMs from other providers. Carriers lock phones mainly to retain customers. Unlocking your phone means removing those restrictions, giving you the freedom to use any mobile carrier’s SIM or eSIM, locally or internationally.
Why unlocking matters for international eSIMs:
- You can avoid expensive international roaming fees
- You gain flexibility to switch between local and global carriers
- You enable the use of a virtual phone number eSIM
3. Why Use an eSIM for International Travel or Remote Use?
eSIMs have revolutionized mobile connectivity. Here’s why:
- No need for a physical SIM card: Just scan a QR code or enter an activation code.
- Multiple profiles: Store multiple carrier profiles on a single device.
- Instant setup: Activate local plans as soon as you land in a new country.
- Cost-effective: Avoid roaming charges and use local data rates.
- Pair with virtual phone numbers: eSIMs are ideal for keeping your personal and business lines separate using a virtual phone number eSIM.
4. Pre-check: Is Your Phone eSIM Compatible?
Before unlocking and setting up an international eSIM, confirm your phone is eSIM-compatible.
For iPhones:
- Go to Settings > General > About
- Look for “Digital SIM” or “eSIM IMEI”
For Android (e.g., Samsung, Pixel):
- Go to Settings > About Phone > Status
- Look for an eSIM IMEI entry
Popular eSIM-compatible devices include:
- iPhone XS and later
- Google Pixel 3 and later
- Samsung Galaxy S20 and newer
- Motorola Razr, Huawei P40 (some models), and more
Ensure your phone has the latest software update for smooth eSIM activation.
5. How to Check If Your Phone is Unlocked
You can’t use an international eSIM if your phone is locked. Here’s how to check:
For iPhone:
- Go to Settings > General > About
- Scroll to Carrier Lock
- If it says “No SIM restrictions,” your phone is unlocked

Alternatively, contact your carrier’s customer support or check through your account portal.
