eSIM Installed but No Internet? What to Check First

You've landed, switched off Airplane Mode and opened your maps app. The travel eSIM is sitting in your phone settings, but nothing loads.

That moment feels worse than it usually is. In many cases, the eSIM is installed correctly and one setting is standing in the way. This guide is about fixing the connection on an eSIM that is already installed. If you still need to add it, start with the ElloSim installation guide instead.

The short answer

Work through the simple checks first: make sure the travel line is turned on, chosen for mobile data and set to allow data roaming, and that you are somewhere the plan covers. Then turn Airplane Mode on and off, or restart the phone.

Don't delete the eSIM as a fix. Reinstalling it isn't guaranteed. If the steps below don't help, contact support and keep the eSIM on your phone.

Before you change anything: keep the eSIM installed

Deleting and re-adding a SIM is a habit some people bring from physical cards. With an eSIM, it can turn a settings problem into a much harder one.

A deleted eSIM can't always be installed again, and it isn't something to test while you're standing in an arrivals hall. Leave the eSIM where it is until support has looked at your order.

The same caution applies to bigger resets. Try the quick steps first, and ask before doing anything you can't easily undo.

Read what your phone is telling you

The status bar gives a useful first clue.

"No Service" or "Searching" means the phone isn't connected to a mobile network on that line. Apple's guidance treats this as a network connection issue and suggests steps such as Airplane Mode and a restart.

Signal bars, but no internet means the phone can see a network. The problem is more likely to be which line is using mobile data, data roaming, or the plan itself.

A connection only on Wi-Fi can be misleading. Your phone may be loading pages over the hotel or airport network while mobile data isn't working at all. Google's Pixel connection help suggests turning off Wi-Fi to check that you are really using the mobile network. The same test works on other phones.

Check 1: are you in a place the plan covers?

A destination plan is built to connect in its listed destinations. If you installed it at home, it may show no service until you arrive, unless home is also in its coverage.

Timing matters too. For most ElloSim plans, the validity period starts when the phone first connects to a network in the destination, but some plans start at installation or purchase. Each plan page states its own rule, and our guide to when to activate a travel eSIM explains the difference.

Check 2: is the travel line switched on?

Phones can keep more than one eSIM, but an inactive line won't connect.

On iPhone, open Settings, then Cellular or Mobile Data, and tap the travel line. Make sure the line is turned on.

On Google Pixel, open Settings, then Network & internet, then SIMs. Tap the travel line and check that Use SIM is on. Other Android phones may use slightly different menu names.

Check 3: is it the line chosen for mobile data?

Your phone uses one line for mobile data at a time. If your home SIM is still selected, the travel eSIM can be installed and active without carrying any of your internet traffic.

On iPhone, Apple's Dual SIM guide shows the path: Settings, then Cellular or Mobile Data, then Cellular Data. Choose the travel line.

On Pixel, set the travel line as the default for Mobile data in the SIMs settings, and make sure mobile data is turned on.

While you're on the iPhone screen, look at Allow Cellular Data Switching. When it's on, Apple says your iPhone can use data from both plans depending on coverage and availability. If you want all your data to go through the travel eSIM, consider leaving it off.

Check 4: is data roaming on for the travel line?

This is the setting most likely to be missed. ElloSim's installation guide asks you to turn on data roaming for the ElloSim line, because that is how it connects to partner networks abroad. Turning it on for the travel line doesn't mean ElloSim charges you a roaming fee.

Your home line is a separate decision. Keep data roaming off there unless you deliberately want to use your home carrier's roaming service, and check its terms if you keep that line switched on.

Check 5: give the connection a fresh start

Once the settings look right, give the phone a moment to register. ElloSim's guide suggests waiting a minute or two after landing.

Still nothing? Turn on Airplane Mode for at least 15 seconds and then switch it off again, as Apple suggests. If that doesn't help, restart the phone.

Apple also suggests installing any iOS update and checking for a carrier settings update. Only do this over a connection you trust and when you have time.

Check 6: try choosing a network yourself

Your phone usually picks a network automatically. Sometimes it stays with one that isn't working well for your plan.

In your mobile network settings, turn off automatic network selection and choose another local network from the list. The ElloSim FAQ notes that not every network on that list will carry your plan, so if one doesn't connect, try the next. You can switch back to automatic selection afterwards.

Check 7: has the data or time run out?

An eSIM that worked yesterday can stop because the allowance or validity has ended. Look at the plan details and the order in your ElloSim account where they're shown.

An Unlimited plan is a slightly different case. A slowdown after the daily high-speed allowance isn't the same as no connection. Our guide to why an unlimited eSIM slows down explains what to look for.

One setting to leave alone: APN

You may see advice online to type in a new APN, the setting that tells your phone how to reach the mobile data network. Don't guess one.

Apple warns that incorrect APN settings can cause you to lose your data connection, and advises against editing them unless told to. Only change an APN if your plan's instructions or ElloSim support give you specific values for your plan.

When to contact support

If you've worked through the checks and still can't connect, it's time to ask for help. Without mobile data, you'll need Wi-Fi to reach support. Use the contact page or email support@ellosim.com.

These details will help support check your eSIM quickly:

• Your order ID.
• Your phone model.
• The country or region you're in.
• What the status bar shows: no service, signal but no internet, or something else.
• The checks you've already tried.

Keep the eSIM installed while you wait. If you're planning a trip and want to avoid surprises, check device compatibility before you buy, then choose a plan from ElloSim destinations.
