eSIM No Service after installation? How to fix it

No Service means the phone is not connected to a mobile network for that line. Data not working means the phone may show signal or 4G/5G, but internet traffic does not load.

If there are no bars or the phone says No Service, fix network registration first. If there are bars but apps do not load, use the eSIM data not working guide.

Walk this checklist first. Most No Service situations resolve after these checks.

• Turn airplane mode off.
• Restart the phone.
• Wait 3–5 minutes after restart for network registration.
• Confirm the travel eSIM is installed.
• Confirm the travel eSIM is turned on.
• Confirm the plan covers your current destination.
• Confirm your phone supports eSIM.
• Confirm your phone is carrier-unlocked if using another provider.
• Keep network selection on Automatic unless support tells you otherwise.

If the issue continues, check for iOS, Android, carrier settings, or system updates before contacting support.

Do not delete the eSIM while troubleshooting. Keep your QR code, activation link, and manual setup details available until the issue is resolved.

Open Settings → Mobile Service / Cellular / Mobile Data. Then walk these steps in order.

1. 1Confirm the travel eSIM appears.
2. 2Tap the travel eSIM.
3. 3Confirm Turn On This Line is on.
4. 4Confirm the travel eSIM is selected for mobile data if you are trying to use it for internet.
5. 5Keep home SIM data roaming off if avoiding home-carrier charges.
6. 6Restart iPhone.
7. 7Toggle airplane mode for 20–30 seconds.
8. 8Leave Network Selection on Automatic unless support says otherwise.
9. 9Move to a place with better signal.
10. 10Check for iOS or carrier settings updates if No Service continues.

Some iPhones show Mobile Service, while others show Cellular or Mobile Data. On iPhone, Apple also recommends checking for iOS and carrier settings updates if No Service continues.

Open Settings → Network & internet / Connections / Mobile network → SIMs or SIM manager. Then walk these steps in order.

1. 1Confirm the travel eSIM appears.
2. 2Confirm the travel eSIM is enabled.
3. 3Confirm mobile data uses the travel eSIM if you want internet from that plan.
4. 4Restart phone.
5. 5Toggle airplane mode for 20–30 seconds.
6. 6Keep network selection automatic unless support says otherwise.
7. 7Move to better signal.
8. 8Check destination and plan validity.

Android labels vary by brand, Android version, region, and carrier.

Pixel setup and SIM settings are usually under Settings → Network & internet → SIMs.

Samsung eSIM management is usually under Settings → Connections → SIM card manager.

As an advanced step, Android or Pixel users may see a Reset Mobile Network Settings option. Use this only after basic checks or if support instructs, because it can reset mobile network-related settings.

Most users should leave network selection on Automatic. The phone will try to register on an available partner network.

Manual network selection can help only if:

• support tells the user which network to try
• automatic selection fails repeatedly
• the destination has multiple partner networks

Do not randomly force networks one by one unless support instructs you. It can make troubleshooting harder.

These states usually mean the phone cannot register on a usable mobile network for the travel eSIM line right now. Possible causes include:

• no available partner network at current location
• plan does not cover destination
• eSIM line is off
• network registration still pending
• phone is carrier-locked
• device does not support eSIM properly
• temporary network issue
• weak indoor signal
• unsupported regional device variant

A travel eSIM will not register correctly if the plan does not cover your current location.

• A plan must include the current country/region.
• Regional plans must include the current destination.
• If a user is near a border, the phone may try another network.
• Validity and usage rules are shown in checkout/order.
• If the destination is wrong, the eSIM may install but not register correctly.

Coverage depends on the plan you bought — availability is not the same for every country.

eSIM support does not always mean the device can use another provider. Carrier-locked phones may block travel eSIMs from other providers, and regional variants can differ.

Check your eSIM compatibility

Some travel eSIMs need data roaming on for the travel eSIM. Roaming usually matters after the line can register on a network. Keep home SIM roaming off if avoiding home-carrier charges.

Should data roaming be on for eSIM?

APN settings affect how mobile data routes after the phone can use the mobile network. If the phone still shows No Service with no bars, fix network registration, plan validity, device support, and carrier lock first.

APN settings for eSIM

• Do not delete the eSIM while troubleshooting.
• Do not repeatedly scan the QR code.
• Do not guess APN settings.
• Do not turn on home SIM roaming unless you understand the charges.
• Do not force random manual networks unless support says so.
• Do not assume the included VPN fixes No Service.
• Do not assume No Service and data-not-working are the same issue.

Have this information ready so support can help quickly:

If the travel eSIM line still cannot register, support may need to check plan status, destination coverage, network availability, device compatibility, or whether the device is blocked, locked, or using an unsupported regional variant.
