Nomad eSIM Not Working? How to Fix It

A Nomad eSIM that will not connect is almost always fixable in under five minutes, and the fix is almost never reinstalling. Work through these checks in order. They run from the most common cause to the least, and the first three fix most problems.

Check 1: is mobile data set to the Nomad line?

Installing an eSIM does not make the phone use it. On iPhone, Settings, Cellular, Cellular Data, and confirm the Nomad eSIM is selected. On Android, Settings, Network and Internet, SIMs, and set the Nomad line as the data SIM. An eSIM that is installed but never selected for data looks exactly like a dead plan: full signal bars on your home line, nothing loading.

Check 2: is data roaming on for that line?

Travel eSIMs work by roaming, so the Nomad line needs its own Data Roaming toggle switched on. This is safe, because the plan is prepaid. On iPhone the toggle lives inside the line's settings, on Android under the eSIM's roaming setting. If you switched roaming off before flying, you may have switched it off on the wrong line. Check both while you are there: home SIM roaming off, Nomad roaming on. Our roaming settings guide explains the split in full.

Check 3: the airplane mode reset

Ten seconds of airplane mode forces the phone to renegotiate with the local network from scratch, which clears the stale state that a long flight and an eager phone accumulate. Toggle it on, count to ten, toggle it off, give it a minute. A full restart is the stronger version if airplane mode does not do it.

Check 4: has the plan actually started, or already ended?

Open the Nomad app and look at the plan's status. Three states cause confusion. Not yet activated: Nomad plans start when the eSIM first connects to a supported network at your destination, or on day 60 after purchase if that comes first. Data exhausted: the app shows remaining balance, and zero explains everything. Expired: validity windows are hard stops. The app answers all three in one glance, which beats an hour of settings archaeology. If the app shows the plan active with data remaining, continue down the list.

Check 5: select the network manually

Phones sometimes cling to a network the plan does not include, especially after crossing a land border. Settings, Cellular, the Nomad line, Network Selection, switch off Automatic, and wait for the list. Try the networks Nomad's app or purchase email names for your country, one at a time, giving each a minute. If a network connects and then drops repeatedly, try the next one on the list rather than fighting it, coverage agreements differ city by city.

Check 6: check the APN

The APN is the doorway between phone and network, and a missing one means signal bars with no internet, the most maddening symptom of all. The Nomad app shows the correct APN for your plan, compare it against Settings, Cellular, the Nomad line, Cellular Data Network on iPhone, or Access Point Names on Android. If they differ, type in what the app says exactly, lower case matters. Most installs set this automatically, the exceptions keep support teams employed.

Check 7: throttled, not broken?

If things load but painfully, you may be meeting a policy rather than a fault. Nomad's unlimited plans give 2 GB a day at high speed, then slow to about 1 or 2 Mbps for the rest of the day, depending on the plan. Nomad's own help centre says so, and 1 Mbps feels broken if you expected 4G. The tell: messaging works, images crawl, video refuses. Nothing on the phone fixes a throttle, it resets with the plan's daily cycle. If this is your daily reality, the honest fix at the next purchase is a bigger fixed data plan rather than unlimited, a distinction we unpack in our guide to what unlimited really means.

Check 8: is the phone unlocked?

A carrier locked phone can download an eSIM profile and then refuse to connect it, a failure that hides behind every other symptom on this list. Settings, General, About, Carrier Lock on iPhone, where anything other than No SIM Restrictions means locked. The two minute check and the carrier by carrier unlock routes are in our unlock guide. This one is worth ruling out early if the phone was bought on an instalment plan.

Check 9: reinstalling, the genuinely last resort

Only after everything above, and only with Nomad support's blessing. Deleting the profile without their say so risks the remaining balance, most travel eSIM codes are single use, and support can see server side whether a reissue is needed. Message them through the app with your ICCID, the plan name, and what you have tried, the list above doubles as exactly the diagnostic report they will ask for.

Nomad eSIM not activating

A plan that shows installed but never activates is usually waiting for its first connection, not broken. Nomad plans start when the eSIM first attaches to a supported network in the destination, or on day 60 after purchase if you have not travelled by then. At home, before you fly, it will sit at not active and that is correct. If you have landed and it still has not started, run checks 1 to 3 above in that order: data line selected, data roaming on for the Nomad line, airplane mode off and on again. If the app shows a start date in the past and no data has moved, contact Nomad support before touching the profile, because reinstalling can end the plan.

Nomad eSIM says No Service

No Service on the Nomad line means the phone has not found a partner network it is allowed to join. Select the network manually as in check 5, and try each listed operator in turn rather than the first one. If every operator refuses, the phone is often still set to a home only or 5G only mode: switch the Nomad line to automatic and to 4G or LTE and try again. A phone that shows No Service on both lines is a phone problem, not a Nomad problem, and a restart fixes most of those.

iPhone and Android: the two different paths

On iPhone the settings that matter live in one place: Settings, Cellular, then the Nomad line, where you set it as the data line, switch on Data Roaming, and choose Network Selection. On Android the same three live in Settings, Network and Internet, SIMs, then the Nomad SIM, and the names vary by brand: Samsung calls it Mobile networks, Pixel calls it SIMs. Whatever the phone, the order is the same: data line, roaming, network. If it still fails, the APN check in check 6 is the last stop before support.

Still stuck, or stuck often?

Every provider has bad days, coverage gaps, and plans that fit some trips badly, we say the same about ourselves in our other guides. If the checks above got you online, that is the outcome we wanted. If Nomad's coverage keeps disappointing where you travel, or the daily slowdown keeps biting, compare before the next trip. Our plans cover 198 countries, every destination page names the networks, and prices start at $1.29. The page price is the checkout price. Our eSIM Price Index shows the going rate for any country, whoever you end up buying from.

Nomad eSIM problems, answered briefly

Why is my Nomad eSIM not connecting to the network?

In order of likelihood: mobile data is not set to the Nomad line, its data roaming is off, the phone needs an airplane mode reset, or the plan has not started or has run out, all checkable in two minutes between settings and the Nomad app.

Why is my Nomad eSIM so slow?

If you are on an unlimited plan, you have likely used the 2 GB daily high speed allowance and been slowed to about 1 or 2 Mbps until the daily reset. If a fixed plan is slow, manual network selection onto a different partner network usually helps.

Should I delete and reinstall my Nomad eSIM?

Not without contacting Nomad support first. Travel eSIM QR codes are generally single use, and deleting an active profile can destroy the remaining balance rather than fix the connection.

Why is my Nomad eSIM not activating?

Because it has not connected to a network in the destination yet. Nomad plans start on first connection, so they show not active until you land, select the Nomad line for data, switch on its roaming, and cycle airplane mode. If it still will not start after that, ask Nomad support before reinstalling.

Why does my Nomad eSIM say No Service?

The phone has not attached to a partner network. Pick the network manually, try each operator in turn, and set the line to automatic mode and 4G or LTE. If both lines show No Service, restart the phone.

Does Nomad work with hotspot?

Yes, Nomad's help centre says its plans support hotspot. On unlimited plans the 2 GB daily high speed allowance covers tethered devices too, and a shared laptop uses it up quickly. Our hotspot guide covers the setup for any provider's eSIM.

What are the Nomad eSIM APN settings?

Most Nomad plans set the APN on their own and need nothing typed in. If the bars are there but nothing loads, open the Nomad app, read the APN it lists for your plan, then compare it with the Nomad line under Settings, Cellular, Cellular Data Network on iPhone, or Access Point Names on Android. Type it exactly as the app shows it, lower case included, and leave username and password empty unless the app gives you some.
