When Should I Reinstall My eSIM?
Reinstallation may help if:
– You accidentally deleted your eSIM
– Installation failed during setup
– The eSIM no longer appears after restart
Reinstallation does NOT fix:
– Slow internet speeds
– Data limits or throttling
– Coverage issues
If you are experiencing connectivity issues, troubleshoot first before deleting your eSIM.
Important: Before You Start
– You can delete and reinstall the same eSIM a limited number of times on the same device. After that limit, contact Support for a replacement eSIM.
– Ensure your device is carrier unlocked.
– Use a stable WiFi connection during installation.
– If your eSIM was deleted from your device, you can usually reinstall it using the same QR code on the same device, as long as it has not been transferred to another device or replaced.
– If the QR code no longer works, contact support for a replacement eSIM.
Method 1: Reinstall Through the Firsty App (Recommended)
Open the Firsty app
Log in to your account
Tap Install eSIM
Follow the on-screen instructions
Method 2: Install Using a QR Code
You can install your eSIM by scanning a QR code.
If the QR is on the same phone you are installing on, that phone cannot scan its own screen. You do not need a second device — skip this method and use Method 3 (manual installation) instead.
On iPhone:
Go to Settings
Tap Cellular (or Mobile Data)
Tap Add eSIM
Select Use QR Code
Scan the QR code
On Android:
Open Settings
Tap Connections
Tap SIM Manager
Tap Add eSIM
Select Scan QR Code
Where to find your QR code:
– The QR code is available inside the Firsty app
– If you cannot access it, request it from support
Method 3: Manual Installation (SM-DP+ Address & Activation Code)
Use this if you do not have another device to scan the QR, or if scanning the QR failed.
You will need:
– SM-DP+ Address
– Activation Code
If you are chatting with support, ask for these two values. They come from the same eSIM as the QR — you do not need a second phone.
On iPhone:
Go to Settings
Tap Cellular
Tap Add eSIM
Choose Enter Details Manually
On Android:
Open Settings
Tap Connections
Tap SIM Manager
Tap Add eSIM
Select Enter Activation Code
These details are provided by support after verification. Do not paste the full LPA:1$… string into one field — the phone needs the address and the code separately.
Changing Devices
Firsty follows a strict 1 eSIM = 1 device policy.
An eSIM can only be installed on one device.
If you are transferring to a new phone:
Contact Support in the Firsty app and ask for a replacement eSIM. We may ask for the EID from your new phone so we can confirm it is a different device.
Steps:
Delete the eSIM from your old device (optional but recommended)
Open Support in the Firsty app (ideally on your new phone) and ask for a replacement eSIM
Install the new eSIM details we send you on your new device
Deleting the eSIM from your old device does not make it reusable. A new eSIM is required for every device transfer.
When NOT to Delete Your eSIM
Avoid deleting your eSIM if:
– You only see “No Service”
– Your connection is slow
– You reached your data limit
– You are troubleshooting roaming or APN settings
Deleting unnecessarily can use up your reinstalls and may mean you need a replacement eSIM from Support.
eSIM Disappeared?
If your eSIM line is no longer visible in your device settings:
Step 1: Restart your device first.
A simple restart often restores the eSIM profile if it did not fully load.
If the eSIM is still missing after restarting:
– Follow the reinstallation steps below
– Or contact support for assistance
Do not immediately delete anything if you are unsure.
If you need assistance, contact support through the Firsty app, and we’ll guide you step by step
