eSIMs are revolutionizing the way we stay connected, especially for travelers. But like any new technology, they come with questions and challenges. The good news? With Roamvy, most disadvantages are either minimized or fully solved.

Here’s an honest look at the common downsides of eSIMs — and how Roamvy makes sure they never get in your way.

1. Not All Devices Support eSIM

The challenge:
Older phones don’t support eSIM technology.

How Roamvy solves it:

• A full compatibility guide is available before you buy.
• We support all major eSIM-ready devices — iPhones (XR and newer), Samsung Galaxy (S20+), Google Pixel (3+), and more.
• With newer devices like iPhone 14 (U.S.) and iPhone Air (2025) going eSIM-only, compatibility will soon be universal.

2. You Need Wi-Fi to Install

The challenge:
Installing an eSIM requires an internet connection, which can be tricky if you wait until you’ve landed.

How Roamvy solves it:

• Install before you travel, using Wi-Fi at home.
• Plans activate automatically upon arrival — no wasted data.
• Airports and hotels typically offer Wi-Fi if needed.

3. Limited Number of Active eSIMs

The challenge:
Phones let you store multiple eSIMs but only keep one or two active at once.

How Roamvy solves it:

• Manage and label multiple eSIMs directly in the app (e.g., “Roamvy Europe,” “Roamvy Japan”).
• Keep your home SIM active for calls/texts while Roamvy powers your travel data.

4. Deleting an eSIM Can End the Plan

The challenge:
Deleting an eSIM profile may remove access to that plan.

How Roamvy solves it:

• Reinstall anytime from the Roamvy app, website, or QR code in your email.
• Our support team can reissue the eSIM if needed.

5. Learning Curve for First-Time Users

The challenge:
New travelers may find the installation process confusing.

How Roamvy solves it:

• Easy, step-by-step guides for iPhone and Android.
• In-app instructions.
• 24/7 support if you need extra help.

6. Concerns About Security

The challenge:
Some travelers worry that eSIMs may be less secure than physical SIMs.

How Roamvy solves it:

• eSIM profiles are encrypted and tied directly to your device, making them harder to clone or steal.
• Unlike physical SIMs, they can’t be lost or swapped by fraudsters.
• Roamvy delivers eSIMs via secure app, web, and encrypted email, ensuring safe activation.
