eSIM Not Working in the UAE? 8 Fixes Before You Contact Support

You've landed in Dubai. You've installed the eSIM. You walk off the plane fully expecting your phone to spring into life with bars of signal and working data. Instead it's sat there saying "No Service" or "Searching" and you're starting to wonder whether the £6 you spent on the eSIM was £6 wasted.

It almost certainly isn't. In the vast majority of cases, the eSIM is fine — something on the phone needs flipping. Here are the eight checks to run through, in order, before you bother contacting support.

This guide is written for the UAE because that's where most of these issues come up, but the same fixes work for Saudi, Qatar, Oman, Bahrain and Kuwait.

1. Is data roaming turned on for the eSIM line?

This is by far the most common cause of "my eSIM isn't working." Your phone considers the travel eSIM to be a roaming SIM, even though you've explicitly paid for it to work in the country you're in. So you need to tell the phone it's allowed to use that data.

iPhone:

• Settings → Cellular (or Mobile Data)
• Tap the eSIM line (it might be labelled "Travel" or with your provider's name)
• Toggle "Data Roaming" ON

Android (varies, but typically):

• Settings → Network and Internet → SIMs
• Select the eSIM
• Toggle "Roaming" ON

If your eSIM was completely silent and this fixes it, you've found your problem. About 60% of "eSIM not working" issues are this exact thing.

2. Is the eSIM set as your data line?

Your phone can only use one SIM for data at a time. If your home SIM is still set as the data line, your eSIM won't get used regardless of whether it's working.

iPhone:

• Settings → Cellular
• Scroll to "Cellular Data" (sometimes "Mobile Data")
• Tap it, and select the eSIM line

Android:

• Settings → SIMs
• Look for "Mobile data" preference
• Select the eSIM

While you're there, you probably also want to turn off data on your home SIM to avoid accidentally racking up roaming charges from your UK or EU carrier.

3. Have you actually activated the eSIM?

A common confusion: installing an eSIM and activating an eSIM are sometimes different things.

When you scan the QR code, you install the eSIM profile on your phone. But many travel eSIMs only "activate" — meaning the validity period starts and you can use data — when the eSIM first connects to a supported network. Until you land in the UAE, the eSIM might appear installed but inactive.

Check your provider's status page or app. If it shows the eSIM as "pending" or "not yet activated" and you're in the UAE, but data isn't working, there might be a registration delay (usually a few minutes, occasionally up to an hour for first connections).

Also: a few providers require you to manually activate via their app or website. If you bought the eSIM yesterday and haven't checked the order confirmation email properly, this might be your issue.

4. Restart your phone

Genuinely. It works.

When your phone lands in a new country it has to negotiate connections with local carriers, register on the network, agree authentication credentials, and a dozen other invisible things. Occasionally one of these steps doesn't complete properly and the phone gets stuck in a weird state.

A full restart — power off completely, wait 10 seconds, power back on — fixes this maybe 25% of the time. Try it before deeper troubleshooting.

Airplane mode toggle (on for 10 seconds, then off) is a faster version of the same thing and works almost as often.

5. Check the carrier the eSIM has selected

Most travel eSIMs auto-select the best available local carrier. But occasionally they get stuck on a less-good one, or on the wrong one entirely.

iPhone:

• Settings → Cellular → eSIM line → Network Selection
• Turn off "Automatic"
• Manually select Etisalat or du from the list
• See if data works on that network

If automatic mode was choosing a network that wasn't actually carrying your eSIM's data routing, manual selection can fix things instantly.

Android:

• Settings → Network and Internet → SIMs → eSIM
• Network operators → choose manually

If the carrier name appears with "no service" next to it, that carrier doesn't have a roaming agreement with your eSIM provider — try a different one.

6. Check the APN settings

This one's more technical, and it's rare, but it does happen.

Some eSIMs require a specific APN (Access Point Name) to be configured. The provider should have set this automatically when you scanned the QR code, but occasionally it doesn't take. Your provider's website or support page will list the correct APN — usually something like travel or internet or the provider's name.

iPhone:

• Settings → Cellular → eSIM line → Cellular Data Network
• Check the APN field matches what your provider says

Android:

• Settings → Network and Internet → SIMs → eSIM → Access Point Names
• Check / add the APN

If you have to manually fix this, it's worth telling support afterwards because it usually means a bug in their QR code generation.

7. Are you actually in a covered location?

UAE coverage is excellent in cities but not literally everywhere. If you're at a specific location with weak signal:

• Move outside or to a window
• Check whether your home SIM also shows no signal — if so, it's a location problem, not an eSIM problem
• Underground parking, certain hotel rooms in the middle of large buildings, and a few specific spots in the desert have genuinely poor coverage

This is rarely the cause but worth ruling out before contacting support.

8. Is the eSIM the correct one for the country?

This sounds obvious but it catches people out. If you bought a global plan, you might need to manually select the UAE region in the provider's app. If you bought a regional Middle East plan, the eSIM should work automatically, but sometimes the provider's system needs to know you've arrived.

Check the provider's app or status page. If you've arrived in the UAE and the system still thinks you're somewhere else, that's the problem.

When to actually contact support

If you've run through all eight checks above and data still isn't working, then it's time to message support. Most travel eSIM providers have WhatsApp support (which works on your home SIM even if the eSIM is dead) or live chat on their site (which works via airport Wi-Fi or hotel Wi-Fi).

When you message them, give them:

• Your order number
• Your phone make and model
• The country you're in
• The exact behaviour you're seeing (no signal? signal but no data? specific error message?)
• Which carrier the eSIM is currently connected to

This makes their job 10x easier and gets you back online faster.

A few preventive habits

For future trips, a few things that reduce the chance of this happening at all:

Install the eSIM at home before flying. You'll usually catch any installation issues in a relaxed environment with Wi-Fi rather than in an airport arrivals hall.

Take a screenshot of your provider's installation instructions. If you need to manually configure something, you'll have it offline.

Keep WhatsApp working on your home SIM. Even if you've disabled data on your home SIM, WhatsApp messaging can still come through over the eSIM's data — as long as one is working you can reach the provider.

Carry your provider's email confirmation offline. PDF it or save it to your photos. If you need to access your QR code again you don't want to be hunting for an internet connection.

The honest reality

eSIMs work reliably the vast majority of the time. When they don't, it's almost always one of the first three issues above — data roaming off, wrong data line selected, or a restart needed. Five minutes of troubleshooting fixes most problems.

The remaining cases are usually provider-side issues that need a quick support intervention. Genuinely faulty eSIM profiles are rare.

If you've followed everything above and you're still stuck, the issue probably isn't on your end — and a good provider will fix it quickly or refund you.
