Installing your Simply eSIM
Set up your eSIM before you travel — everything happens inside the Simply app, no physical SIM needed. Note: screens may look slightly different between app versions, but the steps stay the same.
Install your eSIM in the app
Connect to a stable Wi-Fi network, open the Simply app, select your purchased plan, and follow the in-app installation instructions. We recommend doing this before departure.
Before you start
- A phone that supports eSIM and is not carrier-locked
- A stable Wi-Fi connection while you install
- Install before you travel, then activate when you land
Step by step
Activating on your device
After installing your eSIM in the app, activate the line in your device settings. Choose your phone below:
Open your Cellular settings
In Settings, open Cellular — it appears as Mobile Data in some regions.
Turn on the Simply line
Select the Simply plan under SIMs, then switch on Turn On This Line and Data Roaming.
Send your data through Simply
Back on the Cellular screen, choose Simply as your data line. Leave Default Voice Line on your primary SIM for calls and texts.
Open your SIM settings
Settings → Network & internet → SIMs. On Samsung: Connections → SIM manager.
Turn on the Simply eSIM
Pick the Simply eSIM from the list of SIMs and switch the line on.
Turn on data and roaming
Set mobile data to the Simply eSIM and turn roaming on for that line. Your primary SIM stays in place for calls and texts.
Menu names vary slightly by manufacturer and system version, but the path stays the same.
Still not connected?
- Restart your phone after activating, then wait a couple of minutes.
- Check that data roaming is switched on for the Simply line.
- Try selecting a network manually in your carrier settings.
- A few Android phones need the APN set by hand — email support@thesimply.app and we will send the right settings for your plan.
- Do not delete the eSIM unless our support team asks you to.
