eSIM Not Working? Fix No Service or Slow Data

The first four fixes when an eSIM is not working

First confirm you are at a destination covered by the plan and that the Wanderly line is enabled with data and validity remaining.

1. Enable Data Roaming for the Wanderly eSIM and select it for mobile data. Keep data roaming off for your home SIM.
2. If the current network gives you trouble, turn off automatic network selection and try another network listed for your plan. Allow a minute for each connection attempt.
3. Temporarily turn off other SIMs/eSIMs in SIM settings, leaving Wanderly enabled. This pauses calls and texts on those lines; turn them back on after testing. Do not delete any eSIM.
4. Restart your phone, then turn Wi-Fi off briefly to test mobile data at your destination.

Where to select another network

Choose a network listed for your plan. Ask Wanderly support if the plan details do not name a supported network.

• iPhone: Settings > Cellular (or Mobile Service) > Wanderly eSIM > Network Selection > turn Automatic off.
• Samsung: Settings > Connections > Mobile networks > Network operators > turn Select automatically off for the travel line.
• Pixel: Settings > Network & internet > SIMs > Wanderly eSIM > turn Automatically select network off. Menu names vary by phone.

If you have signal but no internet

Bars only show that the phone can see a network. Mobile data still fails if the wrong SIM is selected, the APN is wrong, or the plan has not started.

• Temporarily turn off other SIMs so the phone cannot switch data back to your home line.
• Check your Wanderly usage page to confirm the plan has data remaining and has not expired.
• Reset the travel eSIM's APN to its default. Only enter an APN manually when your plan details or support team provides one.
• Disable a VPN or Private Relay temporarily. Re-enable it after the mobile connection works.

If the connection is slow or unstable

• Move outdoors or away from thick walls, elevators, underground stations, and crowded venues.
• Change Preferred Network Type from 5G Auto to 4G/LTE. A strong LTE signal can outperform weak 5G.
• Turn automatic network selection off and try the supported networks shown in your plan instructions, waiting about 30 seconds after each choice.
• Check whether a daily high-speed allowance has been used. Some daily plans continue at a reduced speed after the allowance is reached.
• Restart the phone after changing APN or network-selection settings.

What to send support

If the eSIM still cannot connect, send support your order number, current country and city, phone model, the last eight digits of the ICCID, and screenshots of the SIM, data roaming, APN, and network-selection screens. Mention every step you already tried so the team can skip repeated checks.
