An eSIM not working after changing phone usually means the mobile plan was not transferred or reissued for the new device. Copying apps and photos does not necessarily move an eSIM profile.
Keep the old phone and its eSIM unchanged until the new phone connects. A transfer may require the provider’s approval, a replacement installation code or a supported device-to-device transfer.
NoveSIM travel eSIMs are data-only. If you changed phones while a plan was active, contact NoveSIM Support before deleting the profile or scanning the original QR code again.
Quick answer: Check whether the eSIM appears on the new phone. If it does not, do not assume the original QR code can be reused; keep the old profile installed and ask NoveSIM Support whether the plan can be transferred or replaced.
Why an eSIM May Not Move with Your Other Data
A phone backup can restore settings and apps without restoring a provider-issued eSIM. Transfer support varies by phone, operating system and provider. Even when a handset offers an eSIM transfer option, the provider still decides whether that plan is eligible.
Confirm the new phone is unlocked and appears on the eSIM-compatible device list. If the old phone still has service, leave it connected until the transfer is complete.
Check What the New Phone Actually Shows
- Open the mobile or cellular settings and look for the NoveSIM line.
- If the line appears, switch it on and select it for Mobile Data.
- Enable Data Roaming on the NoveSIM line and disable automatic data switching.
- Use Automatic Network Selection and wait several minutes for registration.
- If a manual APN is needed, enter data.esim and leave username and password blank.
If the profile is installed but there is no data, follow the checks for an eSIM connected without internet. That is a connection problem, not necessarily a transfer problem.
If the eSIM Is Missing from the New Phone
Do not repeatedly scan the old QR code. Installation credentials may be single-use, and repeated attempts can obscure whether the profile was already consumed. Use the transfer method offered by the device only when the provider and plan support it.
Send NoveSIM Support the order number, old and new phone models, operating-system versions and the exact message shown on screen. Never send the QR code in a public post or unverified chat.
Protect the Old Profile Until Service Is Restored
Do not erase, trade in or factory-reset the old phone while the travel eSIM remains there and the new device is not working. Do not delete the installed eSIM unless NoveSIM Support specifically instructs you to do so.
If travel is imminent, save tickets, accommodation details and maps offline. The NoveSIM setup overview explains the difference between installation and activation.

FAQ
Why is my eSIM not working after changing phone?
The profile may not have transferred with the rest of the phone data, or the plan may require provider authorisation for the new device. Check whether the line is present before changing settings.
Can I scan the same eSIM QR code on my new phone?
Do not assume so. Many installation codes are single-use. Ask NoveSIM Support whether the plan needs an authorised transfer or replacement.
Should I delete the eSIM from my old phone first?
No. Keep it installed until the new device is connected, and delete it only if NoveSIM Support gives that instruction.
What information should I send to Support?
Send the order number, both phone models, operating-system versions, whether the profile appears on either phone and the exact error message, without exposing activation credentials.
Final Recommendation
When an eSIM is not working after changing phone, first determine whether the profile is missing or merely installed without data. Those situations require different fixes.
Keep the old device and profile intact, use reversible settings checks on the new phone and do not reuse the QR code without confirmation.
If the plan needs moving or reissuing, contact NoveSIM Support with precise device and order details before making any irreversible change.
