No. On current iPhone, Google Pixel, and Samsung Galaxy software, Reset Network Settings normally clears connection preferences without deleting the installed eSIM profile. It can remove saved Wi-Fi passwords, VPN/APN overrides, and Bluetooth pairings, so you may need to reconnect before a travel eSIM registers. co:sim delivers a data-only profile that remains on the device until you deliberately delete it.
Apple, Google, and Samsung describe this reset as a cleanup of network configuration. It does not equal Erase All Content and Settings, and it is not the same action as tapping Delete eSIM. Afterward, the eSIM line can still be enabled, but custom network settings and saved Wi-Fi credentials may be gone. co:sim's QR profile is not reissued merely because you reset network preferences.
On iPhone, open Settings, General, Transfer or Reset iPhone, Reset, then Reset Network Settings. Pixel places the command under System, Reset options, and Reset Wi-Fi, mobile and Bluetooth. Galaxy labels it Reset network settings in General management. Read the confirmation screen: if it says erase all content or remove mobile plans, you are in a different menu.
Reconnect to Wi-Fi, turn the travel line on, select it as the mobile-data line, and allow data roaming if the plan requires it. Give the phone a minute to register before changing APN values. The co:sim plan page lists the underlying network, so compare the displayed operator with that information. If the eSIM still cannot register, contact support with the order details instead of deleting the profile.
#How is a network reset different from deleting an eSIM?
The two commands operate at different levels. A network reset asks the operating system to discard saved connection preferences and rebuild its network configuration. Deleting an eSIM removes the downloaded cellular profile itself. A factory erase is broader still and may offer a separate choice about retaining or removing mobile plans. The wording on the final confirmation screen matters more than the route you took through Settings. If it refers to erasing an eSIM or mobile plan, cancel and return to the network-reset menu.
Before a reset, note the name of the travel line, any custom APN supplied by your provider, and the Wi-Fi password you will need afterward. Keep the co:sim delivery email available, but do not assume a QR code can be scanned a second time. If you are abroad, arrange another way to get online before clearing Wi-Fi credentials. A network reset can be useful when a device has stale network selection or connection preferences, but it cannot repair an expired plan, an unsupported device, or a provider-side provisioning problem.
#What should you do if the eSIM is visible but data still fails?
First check that the eSIM line is enabled and selected as the mobile-data line. Next, inspect the data-roaming setting specified on the plan page, and verify that you are in a supported destination. Reconnect to Wi-Fi if the phone needs to refresh its network information. A small webpage is a better first test than video or a large download. If the phone shows an operator but no data, record the exact error and the displayed network rather than repeatedly changing settings. co:sim support can use the order details to narrow down whether the issue is device configuration or the plan.
#Will resetting network settings stop my eSIM validity?
No. Reset Network Settings changes connection preferences stored by the phone; it does not pause, restart, or extend the provider's validity clock. A co:sim plan may have a particular installation deadline and a separate billing-start rule, both shown on the plan page. Those rules continue to apply even if the phone is offline after the reset. If the plan had already begun billing, reconnecting later does not move its start time. Before you reset, record the current plan status in your account and make sure you can reconnect to Wi-Fi afterward. Once the reset finishes, enable the travel line, select it for mobile data, and check whether the supported network appears. If the validity shown in your dashboard seems wrong, contact support with the order reference; another network reset will not correct a provider-side date.
#Should I delete and reinstall the eSIM if the reset fails?
No, deletion should not be the next troubleshooting step. The reset preserves the downloaded profile, while deleting it can remove the only usable local copy. Some travel QR codes are one-time installation credentials, and rescan support depends on the provider and the particular order. Instead, restart once, confirm that the travel line is enabled, select it for mobile data, and check the plan's roaming and destination requirements. Record whether the phone reports no service, a registration error, or service without data; those are different clues. co:sim support can compare the order and profile details before deciding whether a replacement or fresh installation is possible. Only delete an eSIM after the provider explicitly confirms a safe recovery path for that specific plan.
#Does a network reset affect my physical SIM or saved Wi-Fi?
A network reset generally leaves the physical SIM card in place, just as it leaves the installed eSIM profile on the device. It can, however, erase saved Wi-Fi networks and passwords, Bluetooth pairings, VPN settings, and custom cellular configuration, depending on the phone and software version. Those secondary changes can make a working travel eSIM appear broken until the correct data line and roaming setting are restored. Read your phone's confirmation screen because Apple, Google, and Samsung describe slightly different reset scopes. If you rely on a custom APN or VPN for work, record the approved settings before continuing. Afterward, reconnect to Wi-Fi, check the travel line and operator, and test a small page. co:sim's plan page is the reference for supported networks, while the phone's Settings screen shows which line is active.
