Why Savvy Travellers Are Making the Switch

Many travellers find that using an eSIM means one less hassle: it’s built into the phone, so you never have to swap a tiny physical SIM. Instead, you can buy a local data plan online and download it to your device instantly. The benefits are real; eSIM users are likely to jump from 40 million in 2024 to over 215 million by 2028. eSIM data often costs about 35% less per gigabyte than traditional roaming.

In 2024, manufacturers shipped over 500 million eSIM-capable devices (a 35% rise), so modern phones almost all support eSIM. That means wherever you go, there’s likely an eSIM plan waiting. No more roaming sticker shock – just instant local data abroad.

7 Common eSIM Travel Mistakes to Avoid

Despite the widespread use of eSIM and their simplicity, there are quite a lot of mistakes that people commit:

  • Not checking device compatibility: If your phone is old or locked to one carrier, it can’t use eSIMs, so your eSIM plan won’t work.
  • Skipping proper installation: Not scanning the provider’s QR code or following the instructions can leave the eSIM inactive. Install the eSIM on your phone (you can activate it later).
  • Data roaming off or Aeroplane Mode on: Forgetting to turn on Data Roaming (or leaving Aeroplane Mode on) – mobile data stopped working as soon as you landed.
  • Not selecting the eSIM: If you don’t set the eSIM as your data SIM, the phone will keep using your old SIM. Check in Settings that the eSIM is active for mobile data.
  • Poor coverage: Being in an area with a weak signal means even a well-set-up eSIM won’t connect. Check coverage maps or move where reception is better.
  • Expired or wrong plan: If your eSIM plan wasn’t fully activated (or has expired), you’ll suddenly have no data. Verify in Settings that it shows “Active” and has data left.
  • Phone locked or outdated: A phone locked to one carrier won’t accept other eSIMs, and very old phones or software may not support modern eSIM features.

Troubleshooting eSIM Issues: Getting Back Online

Even the best tech can hiccup. If you face eSIM issues, start with the basics: toggle Aeroplane Mode off and on, make sure Mobile Data and Data Roaming are enabled, and verify the eSIM is the active data SIM in your settings. A quick reboot often clears glitches.

Next, check coverage and plan status. Move to an area with a better signal or set network selection to automatic. In your phone’s settings, ensure the eSIM profile is shown as “Active”. If not, try removing and reinstalling it. Also, update your phone’s software if it’s old. If nothing works, contacting your provider usually does the trick – often it’s just a brief activation glitch on their end.
