APN, Data Roaming & 5G/LTE — Settings Travelers Actually Need

You’ve installed your Roamvy eSIM and activated data, but a few minor settings can make a significant difference in performance, especially when traveling across different regions. Before adjusting any settings, ensure that you’ve completed the eSIM activation process, which ensures your connection works seamlessly across all destinations.

APN, data roaming, and network mode (4G/5G) are three core settings that ensure your eSIM connects properly and stays stable wherever you go.
This guide breaks down what each one does, when to turn it on, and how to adjust them for the best results.

What Is APN — and Why It Matters

APN (Access Point Name) tells your phone how to connect to the mobile network for data. Without it, your eSIM might show a signal but no internet access.

For Roamvy users, the APN is usually automatically configured during the eSIM activation process; however, you can check or enter it manually if needed..

How to Check or Edit APN Settings

iPhone (iOS)

1. Go to Settings → Cellular → Cellular Data Network
2. Under “Cellular Data,” confirm the APN field shows: roamvy (or as specified in your plan instructions).
3. If missing, tap and enter it manually.
4. Return to your home screen — your data connection should now be refreshed.

Tip: If you can't yet activate eSIM on iPhone, follow the activation steps first to ensure this menu is available.

Android

1. Go to Settings → Network & Internet → SIMs → Roamvy eSIM → Access Point Names
2. Tap Add or Edit APN
3. Enter Name: Roamvy | APN: roamvy
4. Save and activate the new profile.

Your device now knows exactly where to route your data traffic.

Understanding Data Roaming

Data roaming allows your eSIM to use partner networks outside its “home” country or region.
For international travelers, this feature must be enabled for the eSIM to function properly.

Why It’s Safe to Enable

Many travelers assume turning on roaming will trigger high charges.
With Roamvy, roaming is built into your prepaid plan, meaning you’ll never be billed extra — you simply need the setting active for connectivity.

To Enable:

• iPhone: Settings → Cellular → [Roamvy eSIM] → Data Roaming → ON
• Android: Settings → Network & Internet → SIMs → Roamvy eSIM → Data Roaming → ON
   

If data isn’t working after landing, toggling roaming ON is usually the quick fix.

Choosing Between 4G/LTE and 5G

Most Roamvy eSIMs support 4G/LTE and, in many destinations, 5G speeds through local network partners.

If your phone supports 5G and the destination offers coverage, enable it for faster browsing, video, and maps.
If 5G isn’t stable in rural or island regions, switching to LTE can improve consistency.

To Adjust:

• iPhone: Settings → Cellular → Cellular Data Options → Voice & Data → Choose 5G Auto or LTE
• Android: Settings → Network Mode → 5G/4G/3G Auto

For most trips, “5G Auto” or “LTE Preferred” gives the best balance of speed and stability.

Quick Checklist Before You Travel

✅ Ensure your eSIM is installed and activated before departure.
✅ The APN field should display 'roamvy' or be auto-filled.
✅ Data Roaming is ON for your eSIM line.
✅ Network mode is set to 5G Auto or LTE Preferred.
✅ Restart your phone once after landing.

Following this checklist ensures instant connectivity in every destination.

Common Issues and Fixes

If issues persist, you can constantly refresh your eSIM connection inside the Roamvy app under My eSIMs → Refresh Connection.
