My eSIM is installed but data is not working

Check these settings in order 1. Make sure you are inside the plan’s included coverage. A fixed-data plan needs both remaining data and remaining validity; an unlimited plan needs remaining validity. 2. Turn on the travel eSIM line and select it for mobile data. 3. Enable data roaming on the travel line. Keep your regular line’s roaming off if needed. 4. Turn off automatic mobile data switching. 5. Toggle airplane mode briefly, then restart the phone if needed. Allow time for network registration. 6. If there are signal bars but no internet, check the APN shown in your private installation details. 7. Temporarily disable a VPN to test whether it is affecting the connection. Do not delete the eSIM. If it still fails, send support your destination, device model, displayed network and exact error. A screenshot of SIM settings can help if private installation codes are hidden.

My eSIM shows no service or no signal

Make sure the travel line can register Being in a covered country does not guarantee reception in every building or remote area. Move to an area with better mobile reception if possible. 1. Check that the country is included in this plan. 2. Turn on the travel eSIM and confirm the plan is still valid. 3. Start with automatic network selection. 4. Toggle airplane mode and allow the phone time to register after turning it off. 5. If automatic selection fails, try a supported network from your plan’s network list using manual selection. Do not select an unrelated network simply because it appears in the phone’s list. Return to automatic selection after testing if appropriate. If no supported network works, contact support with your location and the network names you tried. Keep the eSIM installed.

Do I need to change the APN?

Most phones configure the APN automatically An APN tells the phone how to connect to mobile data. If you have a signal but no internet, check whether your private eSIM instructions provide a specific APN. Use the value for your purchased eSIM. Do not copy an APN from another destination, an unrelated online guide or a different plan. - On iPhone, look under the travel line’s Cellular / Mobile Service settings for Cellular Data Network, if available. - On Android, look under the travel SIM’s mobile network settings for Access Point Names. Enter only the fields your instructions require, save the change and try reconnecting. Leave usernames and passwords empty unless explicitly supplied. If the setting is unavailable or the instructions show no APN, ask support. Do not reset all network settings or delete the eSIM as a first troubleshooting step.

Why is my eSIM data slow or not using 5G?

Speed depends on the connection Coverage, congestion, indoor reception, your phone and the supported network all affect speed. A 5G-capable phone does not guarantee a 5G connection in every location. Unlimited plans can also be subject to fair use management. Try moving to a place with stronger reception, reconnecting with airplane mode and checking the supported networks for your plan. Temporarily disable a VPN to test its effect. Check that your phone’s preferred network mode allows the available mobile technology. Large downloads, cloud backups and hotspot use can make other apps feel slower. Pause them while testing. If the connection is still unusually slow, contact support with your location, network name and approximate time. We can check the specific eSIM; we cannot promise a constant minimum speed in every place.

Can I share data with a hotspot?

Check the selected plan’s details Hotspot availability depends on the plan and device. Where tethering is supported, select the travel eSIM for mobile data and turn on Personal Hotspot or Wi-Fi hotspot in your phone’s settings. Connected devices use the same data allowance and validity as the phone. A laptop can consume data quickly through updates, backups and video calls. Consider disabling automatic downloads before connecting it. If data works on the phone but the hotspot does not, check the hotspot APN instructions for your specific eSIM, if supplied. Also check the phone’s hotspot settings and restart the connection. Do not assume every destination or plan has identical hotspot settings. Contact support if your plan’s details are unclear or sharing still fails. Unlimited fair use rules apply to shared usage too.

Using a regional eSIM across countries

Check each destination is included Regional plans cover only the countries in their coverage list. Confirm the full itinerary before buying. A nearby country is not automatically included. When you enter another included country, keep the travel eSIM selected for data and its roaming enabled. The phone should register on a supported local network; this may take a little time. If it stays connected to an old network or loses service, toggle airplane mode and try automatic network selection again. Use manual selection only for a supported network listed for that destination. Crossing a border does not restart the plan’s validity or reset its data bundle. Outside the plan’s coverage, arrange another suitable plan. Contact support if an included destination does not connect after the usual troubleshooting steps.
