7 Mistakes You're Making with International eSIMs (and How to Avoid Huge Bills)

Hi, & welcome to myesims.com!

Travelling soon? or just need mobile Data Topup? We know how it goes... you're at the airport, excited for your holiday, and then BAM! You get home to a phone bill that costs more than your flight... Not Great!

But don't worry! We’re here to help you stay connected without the stress. Using an eSIM is the smartest way to get online abroad, but if you’re new to the tech, there are a few sneaky traps that could still cost you a fortune.

At myesims.com, we provide Connectivity in minutes in over 160+ countries... No Contracts... just Best Prices!

Let’s dive into the 7 biggest mistakes you’re making with international eSIMs & how to fix them Fast!


1. Not Checking Device Compatibility (Oops!)

This is the big one... the "Number 1" mistake people make! Imagine buying a shiny new eSIM for your trip to Paris, only to find out your phone doesn't even support eSIM technology... Total Nightmare!

Most modern phones like the iPhone 11 & newer, Samsung S20+, & Google Pixels are all set... but older models might not be.

How to avoid it:

  • Ensure your device is eSIM Compatible!
  • Check our FAQs for a full list of supported devices before you buy.
  • Make sure your phone is Network Unlocked. If your phone is tied to a specific provider, a travel eSIM won't work!

2. Leaving Data Roaming "ON" for your Primary SIM

This is how the "Big Bills" happen... your phone is clever, maybe too clever! If your home SIM is still active & "Data Roaming" is switched on, your phone might sneakily use your home provider’s expensive data if the eSIM signal dips... Ouch!

The Fix:

  • Go to your settings...
  • Find your Primary SIM (the one from home)...
  • Turn OFF Data Roaming for that specific SIM card!
  • Only keep "Data Roaming" ON for your new myesims.com travel eSIM.

3. Waiting Until You Land to Activate

Landing in a new country is chaotic... finding your bags, getting a taxi, checking maps... The last thing you want is to be hunting for free airport Wi-Fi just to download your eSIM!

If you wait until you land, your phone might automatically connect to a local network using your home SIM... and those first few megabytes can be Pricey!

The Pro Move:

  • Buy now & activate in minutes!
  • Set up your eSIM while you're still at home or on the airport Wi-Fi before you take off.
  • Most of our plans only start their "validity period" when you actually connect to a network in your destination... so you don't lose any days!

4. Buying the Wrong Region (Check the Map!)

Heading to Europe? Great! But are you visiting just one country or jumping around?

We see people buy a single-country eSIM for France & then hop over to Switzerland... only to find they have no data because Switzerland isn't in the EU!

Stay Connected everywhere:

  • If you're touring, grab a Europe Regional eSIM covering 30+ countries!
  • Doing a world tour? Check out our Global Plan for coverage in 130+ destinations!
  • Always verify the "Country List" on the product page before you checkout.

5. Background Data Guzzlers (The Silent Killers)

Your apps are hungry... very hungry! Even if you aren't using your phone, apps like Instagram, TikTok, & Cloud Backups are constantly refreshing & downloading data in the background.

On a limited travel data plan, this can eat through your GBs before you've even posted your first beach selfie... Not ideal!

Tips to Save Data:

  • Turn off "Background App Refresh" in your settings.
  • Set your Photos app to "Only Sync on Wi-Fi".
  • Download your Google Maps for offline use before you leave the hotel!

6. Not Knowing Your Data Balance

There’s nothing worse than your data cutting out right when you're trying to call an Uber in the middle of a busy city...

Many travelers "set & forget" their eSIM... but they forget to check how much data they have left!

The Solution:

  • Keep an eye on your usage!
  • At myesims.com, we make it easy to top-up.
  • If you see you’re running low, just hop back onto our site & grab another package... Easy!

7. Thinking You Need a Phone Number

Most travel eSIMs are Data-Only. This means no traditional "texting" or "calling" via a phone number.

The mistake? People try to make a standard international call & get hit with massive charges from their home provider because they didn't use the eSIM data!

Please note: At myesims.com, our plans are data-only and do not include a local phone number for voice calls or SMS.

The Modern Way:

  • Use WhatsApp, FaceTime, or Messenger for all your calls & texts.
  • It’s 100% Free over your eSIM data!
  • You & your family stay connected... Hassle-Free!
