Nomad eSIM Not Working? Fixes That Actually Help (2026)

Ninety percent of "Nomad eSIM not working" problems come down to three settings on your phone, not a broken eSIM: data roaming is off, the wrong line is set for data, or the APN is missing. Work through the fixes below in order. Each one takes under a minute, and most travellers are back online before they reach the end. If none of it helps, the last section covers how to tell when the fault is genuinely Nomad's side and how to get it fixed fast.

Have you turned on data roaming for the Nomad eSIM?

This is the single most common cause, and it trips up experienced travellers too. A travel eSIM connects to a local partner network in the country you are visiting, and your phone treats that as roaming - so if data roaming is off for that line, you get nothing.

Nomad is explicit about this. Their help centre states that "data roaming should be enabled for all Nomad eSIMs, regardless of the destination or whether the plan includes a local number," and that this is universal for every country (Nomad help centre).

• iPhone: Settings > Mobile Service > tap your Nomad plan > turn on Data Roaming.
• Android (Samsung shown): Settings > Connections > Mobile networks > Data roaming on. On stock Android it is Settings > Network and internet > SIMs > select the Nomad SIM > Roaming.

Do not worry about "roaming charges" here - this is your prepaid Nomad data, not your home network, so enabling roaming for this line does not bill you.

Is the Nomad eSIM set as your data line?

If you have two SIMs active (your home number plus the Nomad eSIM), your phone can still be routing data through your home network while showing the Nomad line as connected. You have to point mobile data at the Nomad plan.

• iPhone: Settings > Mobile Service > Mobile Data > choose your Nomad plan. Leave "Allow Mobile Data Switching" off so it does not fall back to your home line.
• Android: Settings > Connections > SIM manager > Mobile data > select the Nomad SIM.

Keep your home SIM active for calls, texts, and 2FA if you want. You are only moving the data duty to the Nomad line. Nomad's own troubleshooting confirms the eSIM must "function as your device's active line for data" for it to connect (Nomad help centre).

Do you have the correct APN entered?

An APN (Access Point Name) tells your phone how to reach the data network. Nomad sources its eSIMs from several underlying networks, so the correct APN depends on which one your plan came from. The value is listed in your Nomad installation email and on the Manage page of the Nomad app - use that exact string, not a generic one from a forum.

• iPhone: Settings > Mobile Service > Mobile Data Network. Enter the APN under the "Mobile Data" section. Many Nomad plans need no manual APN on iPhone, so only edit this if you are still stuck.
• Android: Settings > Connections > Mobile networks > Access Point Names. If "Nomad" is not listed, tap the menu > Reset to default, then Add a new APN, name it "Nomad," and paste the APN value from your Nomad email.

After saving an APN, toggle airplane mode on and off, or restart the phone, so the change takes effect.

Have you actually arrived, and is there coverage?

Timing catches a lot of people out. A Nomad eSIM connects to the local network at your destination, so if you land and it still says "No Service," give it a few minutes - the phone has to find and register on a partner network. Nomad notes that after changing eSIM settings you should "wait 1 to 5 minutes for changes to take effect."

Two things to check here:

• You are in the plan's coverage area. A country or regional plan only works inside the countries it lists. It will not connect during a layover in a country the plan does not cover.
• Automatic network selection found a partner. If it did not, switch it off. Settings > Mobile Service/Mobile networks > Network selection > turn Automatic off, then pick a network from the list. Nomad specifically recommends manually selecting a partner network if automatic selection fails.

Tried everything and still nothing?

Run this short reset sequence, which is the same one Nomad's support suggests before escalating:

1. Airplane mode on for 30 seconds, then off.
2. Restart the phone, or fully power it off for at least two minutes. Nomad calls this out because a reboot forces your device to re-register on the local network with the new settings applied.
3. Toggle the eSIM itself off and back on in your mobile settings.
4. Turn off Wi-Fi so the phone is forced onto mobile data, which confirms whether the eSIM works.
5. Disable any VPN, and if you are on 5G with no luck, force LTE/4G.

If data comes back after any of these, you are done. If it does not, move to the last check.

When is it genuinely Nomad's side, and what do you do?

Sometimes the eSIM really is faulty or the partner network is down, and no amount of settings will fix it. Signs it is not you:

• You have confirmed roaming, data line, and APN are all correct, and a restart changed nothing.
• The Nomad app shows the plan as installed but it will not start after you have arrived.
• Other phones on the same network work fine, so it is not local coverage.

At that point, contact Nomad support through the app or their help centre. Their guidance is to send screenshots showing "No Service" plus your eSIM details so they can diagnose it. A genuinely faulty eSIM can be replaced. As with any provider, policies and support response times can change, so check Nomad's current terms as of 2026.

If you keep fighting the same eSIM, it may be worth trying a different provider next trip. eSIMpass sells fixed-data plans for 200+ destinations from £2.59, with real top-up if you run low and a "My eSIMs" dashboard that shows your data usage live, so you are never guessing whether a plan is actually working. It installs the same way, by scanning one QR code, and like Nomad it is data-only, so you keep your home number for calls and 2FA through dual SIM. Nomad is a solid data-only option with handy referral credit; the honest pitch for eSIMpass is transparency and live usage, not that Nomad is bad.

The bottom line

Almost every "Nomad eSIM not working" case is a settings fix: turn on data roaming for the Nomad line, set it as your data line, and enter the correct APN from your Nomad email. Then give it a few minutes on arrival, try manual network selection, and restart. If a clean run through all of that still fails, it is fair to treat it as Nomad's side - contact support with screenshots for a replacement. And if the hassle keeps repeating, a transparent alternative like eSIMpass, with live usage tracking and top-up from £2.59, is worth a look for next time.

Why does my Nomad eSIM say "No Service" after I land?

Usually because data roaming is off for the Nomad line, or the phone has not yet registered on a local partner network. Turn on data roaming for that eSIM, wait one to five minutes, and if it still fails, switch off automatic network selection and pick a network manually.

Do I need to keep data roaming on for my Nomad eSIM?

Yes. Nomad says data roaming should be enabled for all its eSIMs in every country, because your phone treats the local partner network as roaming. This uses your prepaid Nomad data, so it does not trigger charges from your home network.

Where do I find the right APN for my Nomad eSIM?

In your Nomad installation email and on the Manage page in the Nomad app. Because Nomad uses several underlying networks, the APN varies by plan, so use the exact value they provide rather than a generic one from a forum.

My Nomad plan is installed but will not activate. What now?

If you have arrived at the destination and confirmed roaming, data line, and APN, restart your phone and wait a few minutes. If it is still stuck, contact Nomad support through the app with screenshots of your settings and the "No Service" status so they can diagnose or replace a faulty eSIM.

Can I switch to a different eSIM without losing my phone number?

Yes. Data-only travel eSIMs like Nomad and eSIMpass never touch your home number - it stays active on your original SIM through dual SIM. You just install the new eSIM by QR code and set it as your data line.
