Global eSIM Reset Network Settings While Abroad: A Guide

A Global eSIM reset network settings while abroad action clears saved Wi-Fi passwords, VPN configurations, Bluetooth pairings, and manually entered APN details, and it switches your phone back to automatic carrier and network selection.

It does not delete your eSIM profiles and it does not erase files, photos, or apps.

The real risk is smaller but still annoying: after the reset, your phone may stop treating your travel eSIM as the active data line, so you have to manually reselect it before data works again.

This matters most on a multi-country trip, where you might be tempted to "reset everything" the moment a network hiccup happens in a new city. Understanding the difference between a network settings reset, deleting an eSIM, and erasing the whole phone can save you from an unnecessary support call or a lost afternoon re-configuring your device in an airport lounge.

What Reset Network Settings Actually Removes on iPhone

According to Apple's own support documentation, Reset Network Settings on iPhone removes previously saved Wi-Fi networks and passwords, resets cellular settings to their defaults, deletes VPN and APN settings you have added manually, and forgets paired Bluetooth devices so you will need to re-pair headphones, car systems, or a smartwatch afterward.

• Removed: saved Wi-Fi networks and passwords, manually added VPN profiles, custom APN entries, Bluetooth device pairings.
• Reset to default: cellular data toggles, data roaming preference, preferred network type (such as 5G Auto vs 5G On), and which line is set as your default for cellular data and iMessage.
• Not removed: your eSIM profiles themselves. Apple's guidance distinguishes this reset from actions that erase the device, which is the point where eSIM profiles are actually deleted.

For the exact current wording Apple uses, see Apple's iPhone reset settings guide. Because Apple periodically adjusts iOS menu wording between major releases, it is worth checking that page directly if you are troubleshooting on an unfamiliar iOS version overseas.

Reset Network Settings vs Deleting an eSIM vs Erasing the Phone

These three actions are often confused, and abroad is the worst place to guess wrong.

If your travel eSIM stops passing data, deleting and reinstalling that single profile is a much more targeted fix than a full network reset, and it is far less disruptive than erasing the phone. If you are not certain your handset even supports eSIM properly, it is worth checking eSIM device compatibility before assuming a settings problem is the cause.

Record These Settings Before You Reset Network Settings Abroad

Because a network reset wipes saved configurations rather than backing them up, write these down first, ideally in a notes app that works offline:

• Hotel, Airbnb, or coworking Wi-Fi passwords you will need to rejoin.
• VPN server addresses, protocols, and login credentials for any VPN app you rely on for secure banking or work access.
• Data roaming status per line, since a phone with a home eSIM or physical SIM plus a travel eSIM tracks roaming separately for each.
• Manually entered APN details, if your provider required one instead of automatic activation.
• Personal Hotspot name and password, especially if you are sharing one connection between two devices, as covered in the guide on sharing one travel eSIM between two people.

If you have not yet activated your eSIM for the trip, it is also worth reviewing when activation should happen relative to arrival, covered in Should I Install My eSIM Before Travel?, since installing too early or too late can look like a settings problem when it is actually a validity window issue.

Android Menu Names Vary by Device

Unlike iOS, where the reset lives in one consistent place, Android's reset menu location and wording depends on the manufacturer's skin:

• Google Pixel: Settings, then System, then Reset options, then "Reset Wi-Fi, mobile & Bluetooth." Google's own support documentation confirms this path and notes it resets network settings without erasing personal data or apps.
• Samsung One UI: as of recent One UI versions, this is typically found under Settings, then General management, then Reset, then "Reset network settings." Samsung does not publish a single centralized reset page comparable to Apple's or Google's, so treat this menu path as approximate and confirm the exact wording on your own device before relying on it.
• Other Android OEMs (Xiaomi's HyperOS, OnePlus's OxygenOS, and others) may nest the same function under "Additional settings" or "Backup & reset," and exact wording changes between OS versions.

For the current official path on Pixel devices, see Google's Pixel network reset support page. On most Android phones this reset behaves similarly to Apple's version: it clears Wi-Fi, Bluetooth, and mobile network preferences, but it does not remove an installed eSIM profile. A full factory reset is the Android equivalent of Apple's Erase All Content and Settings, and that is the step that actually deletes eSIM profiles.

A Safer Sequence Before You Reset Network Settings While Abroad

Because a reset forces you to redo Wi-Fi logins, VPN setup, and eSIM line selection, try these lower-risk checks first, in order:

1. Toggle Airplane Mode on, wait ten seconds, then turn it off.
2. Restart the phone completely rather than just toggling settings.
3. Open cellular or mobile network settings and confirm the travel eSIM, not your home line, is selected for Cellular Data.
4. Turn off Automatic network selection and manually pick a partner network if the automatic option keeps failing.
5. Confirm Data Roaming is switched on for the travel eSIM line specifically, since each line has its own roaming toggle.
6. Check whether the provider requires a manual APN and re-enter it exactly as instructed.

Only reach for a full network settings reset if all of the above fail, since it is a broader action than any single one of these checks. If you are still stuck after trying them, a dedicated troubleshooting walkthrough like eSIM Not Working After Landing? 7 Fast Fixes covers steps beyond the reset itself.

Recovery Checklist: Confirming Your Travel eSIM Is Selected for Data

Once you have reset network settings, run through this list before assuming the problem is fixed:

• Reconnect to known Wi-Fi networks using the passwords you recorded.
• Reinstall and log back into your VPN app if you use one for secure access.
• Go to Cellular or Mobile Network settings and explicitly set the travel eSIM as the line used for Cellular Data.
• Turn Data Roaming back on for that same eSIM line. Resetting cellular settings to their defaults, as Apple and Google both describe it, commonly leaves data roaming switched off until you turn it back on, so treat this as a step to check rather than assume.
• Re-check preferred network type (5G Auto, LTE, or similar) matches what worked before the reset.
• Re-pair any Bluetooth accessories you use for calls or navigation.

If your phone is also locked to a specific carrier, confirm the eSIM restrictions still apply as expected after the reset; the guide on using a travel eSIM on a locked iPhone explains what a carrier lock does and does not affect.

Why a Global eSIM Reduces How Often You Need This

On a multi-country itinerary, a single Global eSIM plan that covers many destinations under one profile means fewer eSIM swaps at each border, and fewer chances for the phone to get confused about which line should carry cellular data.

Instead of installing and deleting a new local eSIM in every country, which is a common trigger for accidentally resetting network settings out of frustration, one global profile stays active for the whole trip while you simply confirm data roaming is on for it.

If you also want to keep your home number reachable for calls and texts alongside a data-only travel eSIM, see Global eSIM: Keep Your Home Number While Traveling for how dual-line setups typically work.

Frequently Asked Questions

Does resetting network settings delete my eSIM abroad?

No. Reset Network Settings on both iPhone and Android clears Wi-Fi, VPN, APN, and Bluetooth data, but it does not remove installed eSIM profiles. Only deleting a specific eSIM, or erasing the entire device, actually removes eSIM profiles.

Will reset network settings fix "No Service" faster than reinstalling my eSIM?

Not necessarily. A reset addresses broader settings conflicts, while a "No Service" message is more often caused by the wrong line being selected for cellular data or data roaming being switched off, both of which you can check and fix without a full reset.

Can I still reset network settings if I have no internet connection abroad?

Typically yes. Apple and Google both describe Reset Network Settings as an on-device settings change rather than a process that depends on an active network connection, so it is generally possible to trigger it offline. You will, however, need working Wi-Fi or cellular afterward to rejoin networks and reconfigure VPN access.

Does this affect my home SIM if I have both a physical SIM and a travel eSIM?

Yes, the reset applies to all lines on the device, not just the one causing problems. Both your home line's roaming and network preferences and the travel eSIM's settings return to default, so recheck both afterward.

Should I reset network settings before or after installing a new eSIM in a new country?

Try it before, if at all, since resetting after a fresh install can undo roaming and default-line settings you just configured. If you are unsure your device fully supports the eSIM you plan to use, confirm compatibility on the eSIM device compatibility page first.
