Nomad eSIM Not Working Fixes for iPhone and Android

Key takeaways

Most "not working" cases are settings: Nomad selected for mobile data + roaming on for that line.
Turn off automatic data switching so the phone cannot silently fall back to your home SIM.
Toggle airplane mode or restart before trying anything drastic.
Never delete an active Nomad eSIM while troubleshooting — it is single-use and cannot be reinstalled.
If checks fail, capture screenshots of settings and contact Nomad support before removing anything.

The five checks that fix most problems

Check	What to do
Destination	Confirm you are in the country/region listed on the exact plan
Data line	Choose Nomad, not your home SIM, for mobile data
Roaming	Turn on data roaming for the Nomad line
Switching	Disable automatic mobile-data switching
Refresh	Toggle airplane mode, wait, then restart if needed

Nomad says activation may not happen until the device finds a supported network with data roaming on. A plan can look inactive in the app for a few minutes even after arrival, so refresh and wait before assuming it has failed.

If you have signal but no internet

Check the APN. Nomad publishes provider-specific APN settings and says username/password fields should generally be left blank. Use only the APN shown for your Nomad provider; do not copy a random internet APN into your phone.

If the correct APN is already there, toggle airplane mode. If that fails, turn off automatic network selection and try a supported available network. Restart the phone after changes.

Troubleshooting decision tree

Follow this path in order. It covers the same verified checks as the table above, but shows exactly when to stop and contact support instead of deleting anything.

1. Is the Nomad line selected for mobile data?

No Select Nomad (not your home SIM) as the mobile-data line, then retest.

Yes Go to step 2.
2. Is data roaming ON for the Nomad line?

No Turn roaming on for the Nomad line — Nomad plans need it to activate. Retest.

Yes Go to step 3.
3. Is automatic mobile-data switching turned OFF?

No Disable it so the phone cannot silently fall back to your home SIM. Retest.

Yes Go to step 4.
4. Did an airplane-mode toggle (then restart) fix it?

Yes Done — the network refresh was all it needed.

No Go to step 5.
5. Signal but no internet — does the APN match Nomad's published setting for your provider?

No Enter the exact APN Nomad lists for your plan's provider (username/password blank), restart, retest.

Yes Turn off automatic network selection, pick a supported network manually, restart. Still down? Go to step 6.
6. All checks failed

Stop Screenshot your eSIM settings, errors and order details, then contact Nomad live chat. Do not delete the eSIM — it is single-use and deletion may invalidate it.

Decision path based on Nomad's own activation, APN and deletion guidance (checked 2026-08-28). Every step is reversible except deleting the eSIM.

iPhone quick route

Open Settings > Mobile Service/Cellular. Ensure the Nomad line is on, chosen under Mobile Data and has roaming enabled. Turn off cellular-data switching. If the eSIM cannot be added, check Wi-Fi, carrier unlock and whether it is already present in the SIM list. See Nomad eSIM compatible devices for the unlock check.

Android quick route

On Samsung: Settings > Connections > SIM manager. On Pixel/other Android: Settings > Network & internet > SIMs. Set Nomad as mobile data, enable roaming, then follow Nomad's APN guidance only if needed.

Never delete first

Nomad warns that deleting an active eSIM may invalidate it and prevent restoration. Take screenshots of settings, errors and your order details first. Its eSIMs are single-use/non-transferable, so deletion is not a harmless reset button.

When to contact support

Use Nomad live chat through the website or app after the checklist. Send: order email, phone model, OS version, destination, screenshots of eSIM settings, error text and the steps already tried. That lets support diagnose rather than ask you to repeat the basics.

Coupon note: If you are buying a replacement plan, ESIMDUDE15 gives 15% off eligible Nomad plans. Do not use it as a reason to delete a plan that support can still repair.

FAQ

Why does Nomad say not activated?

It may need to connect to a supported local network with roaming enabled. Refresh the app after a few minutes and confirm Nomad is the data line.

Should I delete and reinstall Nomad eSIM?

No—not before speaking with support. Nomad warns deletion can invalidate the profile.

What APN should I use?

Use only the provider-specific APN in Nomad's official instructions; leave username/password blank unless Nomad says otherwise.

Bottom line

Fix settings in order, preserve the eSIM, then send support useful evidence. Most failures are a data-line, roaming or registration issue—not a reason to panic at the airport.
