eSIM Not Working Abroad? What to Check After Landing

An eSIM not working abroad needs a checklist before another purchase. Start with your plan details, then follow the settings checks below. Keep the eSIM installed while you investigate: Apple advises against deleting it during troubleshooting unless your provider directs you to do so.

What should I check before changing settings?

Check your plan's destination, activation instructions, remaining data and expiry date first. Then check that the travel line is enabled; Apple explains how to turn on an inactive line.

If installation never finished, connect to Wi-Fi and follow our eSIM installation guide. Apple requires Wi-Fi or a hotspot for setup, with exceptions for some eSIM-only models in certain locations.

Check your device is eSIM-compatible and carrier-unlocked. On iPhone, open Settings > General > About and find Network Provider Lock. “No SIM Restrictions” means the phone is unlocked; using another provider requires an unlocked iPhone.

Record whether the problem started during installation, immediately after arrival, or after data had already worked. Keep that detail for support.

How do I select the travel eSIM for mobile data?

Choose the travel eSIM as your mobile data line in the phone's settings. On Pixel, only one SIM can be the default for data.

Use the route for your device:

• iPhone: Open Settings > Mobile Data > Mobile Data, then select the travel line.
• Google Pixel: Open Settings > Network & internet > SIMs. Under Your primary SIMs, choose the travel SIM for Mobile data.
• Samsung Galaxy: Open Settings > Connections > SIM card manager > Mobile data, then select the travel SIM.

For installation instructions, see our guides for iPhone and Android.

Should data roaming be enabled on the travel eSIM?

Enable roaming on the travel eSIM if your plan's setup instructions require it. The setting allows data through another provider's network outside your provider's own coverage.

On iPhone, select the relevant line under Mobile Data, then open Mobile Data Options > Data Roaming. On Galaxy, the setting is under Settings > Connections > Mobile Networks.

Keep your home line's data roaming switched off if you do not intend to use its roaming data. Check the selected line before changing anything. Keeping your home eSIM active can still incur roaming fees, so check its terms separately.

What should I do if the phone shows No Service?

Try reconnecting with Airplane Mode, then restart the phone if needed, following Apple's connection checks. If signal remains weak, Google recommends trying another location and checking coverage with your provider.

Follow these steps for your device:

1. On iPhone, turn Airplane Mode on for at least 15 seconds, then off.
2. If that fails, restart your iPhone. For Pixel, Google recommends powering off for 30 seconds before switching on.
3. On iPhone, connect to Wi-Fi and open Settings > General > About. Install a network provider settings update if one appears.
4. On Pixel, switch Wi-Fi off to check the mobile connection, then try loading a webpage.

Make one change at a time and note the result before continuing.

Could an incorrect APN stop mobile data working?

Yes: Apple warns that incorrect APN settings can interrupt mobile data. Change them only when your provider supplies instructions and confirms the correct values.

APN means Access Point Name and defines the network path for mobile data. Ask support to compare your settings with the requirements for your exact plan.

On iPhone, viewing or editing the APN depends on your provider allowing it. On Pixel, Access point names appears among mobile network settings, although available options vary by phone and Android version. Avoid copying values from instructions for a different plan.

Should I delete and reinstall the eSIM?

No: Apple says to keep the eSIM during troubleshooting unless your provider instructs otherwise. Its guidance says that deleting an eSIM requires contacting the provider for a replacement.

For iPhone activation problems, Apple instead suggests turning the affected line off and back on. Follow that specific instruction without choosing Delete eSIM.

If you have already removed the plan, contact support before attempting another installation. Ask for the recovery instructions for your order. Our guide to deleting or reusing an eSIM explains what to consider before removal.

Do I need a top-up or a new plan?

Consider more data if your allowance is used up, or a new plan if its validity has ended. Some Simnetic plans allow top-ups, so check your existing plan before choosing a replacement.

For comparison, these fixed Global plan prices were checked on 15 October 2026 and can change. See the Global eSIM page for current details.

Validity is how long the plan lasts once active. Check the destination list and activation policy before selecting another plan.

Simnetic tip: Top-ups are available on some Global plans; check whether your existing plan supports one first.

What should I send support if nothing works?

Send your order reference, phone model, destination, error message and the checks you have completed. Ask support to verify activation, plan status and local coverage; Apple recommends checking account and network issues with your provider.

Contact our team through in-app help or [email protected]. Include screenshots showing the selected data line and roaming setting. Mention whether the eSIM ever worked and when it stopped.

For an iPhone setup failure, Apple recommends recording the exact error and having the IMEI or EID available. Find those identifiers in Settings > General > About, and provide them privately if support requests them.

Once you know which destination and dates you need, compare Simnetic travel eSIM plans.
