Here you’ll find guides, tips, and answers to common questions about activating, managing, and troubleshooting your eSIMs.

Getting Started

Everything you need to start using your Esim-Serv plan.

What is an eSIM and how it works

An eSIM (embedded SIM) is a digital version of a traditional SIM card that’s already built into your device. With Esim-Serv, there’s no need to wait for delivery or insert anything — you simply scan a QR code to download your plan and get connected instantly.

Once installed, the eSIM allows your phone to connect to local networks in your destination country, just like a physical SIM. You can store multiple eSIMs on one device and switch between them anytime.

Device compatibility list

Esim-Serv eSIMs work on most modern smartphones, tablets, and smartwatches that support eSIM technology. To make sure your device is supported and ready for activation, please visit our Compatibility Devices page for the complete and regularly updated list.

How to purchase and activate an eSIM
  1. Go to the Esim-Serv Shop and choose your plan.
  2. Complete your purchase securely.
  3. You’ll receive an activation email with your QR code and setup instructions.
  4. On your phone, go to Settings → Cellular / Mobile Data → Add eSIM.
  5. Scan the QR code — installation takes about a minute.
  6. Once installed, turn on the eSIM and ensure Mobile Data is active.

Tip: Your plan activates automatically once your device connects to the network at your destination.

How to scan your QR code and install manually
  1. Open Settings → Mobile Data → Add eSIM.
  2. Choose Enter details manually.
  3. Enter the SM-DP+ Address and Activation Code found in your Esim-Serv email.
  4. Wait for installation to complete, then activate the eSIM.
Tips before you travel
  • Install your eSIM while you have Wi-Fi access (at home or airport).
  • Do not activate data until you arrive at your destination — this prevents early usage.
  • Keep your QR code email safe in case you need to reinstall.
  • Make sure Mobile Data Roaming is ON when abroad.
  • Restart your device after arrival for the best signal detection.

Using Esim-Serv Abroad

Stay connected wherever you go.
Activating your eSIM at your travel destination

Your eSIM automatically activates when you arrive and your phone connects to the supported local network.
If not, turn Airplane Mode ON, wait 10 seconds, then turn it OFF.

If still inactive, ensure Mobile Data and Data Roaming are enabled.

Switching between eSIM profiles
  • iPhone: Settings → Cellular → Select eSIM → Turn On
  • Android: Settings → Network & Internet → SIMs → Select eSIM → Activate

Turn off unused eSIMs to avoid roaming charges or connection conflicts.

Recommended data settings and APN information

Some devices require manual APN setup. Check your activation email for the correct APN name, then:

  1. Go to Settings → Mobile Network → Access Point Names (APN)
  2. Tap Add New and enter the provided APN
  3. Save and select it, then restart your phone
Avoiding roaming fees with dual-SIM devices
  • Keep your physical SIM active for calls/SMS only
  • Set Esim-Serv as your data line
  • Turn Data Roaming OFF on your physical SIM
  • Turn Data Roaming ON for Esim-Serv
Managing data usage while traveling
  • Use Wi-Fi whenever available
  • Disable background app refresh
  • Turn off auto-updates while roaming
  • Use Low Data Mode (iPhone) or Data Saver (Android)
