Looking For Global Travel Data Roaming? Here Are 10 Things You Should Know Before You Fly

Hi, and welcome to myesims.com! Azz here from the Customer Services team... are you getting ready for that big dream trip? Whether it’s the neon lights of Tokyo, the pasta in Rome, or a business trip to New York... there’s one thing that can totally ruin the holiday vibe: Bill Shock! Oh yeah... we've all heard the horror stories of travellers coming home to a $1,000 phone bill just for checking a few maps & posting some sunset photos.

Travelling soon? Or just need a mobile Data Topup? Don’t worry... I’ve got your back! At myesims.com, we live & breathe Travel Technology, and our goal is to keep you connected without the stress. Here are 10 things you absolutely MUST know about global travel data roaming before you head to the airport!


1. The "Bill Shock" is 100% Avoidable!

First things first... let’s talk about that primary line. The most important thing you can do when you land is turn off data roaming on your home carrier's SIM card. Why? Because the second you touch down, your phone starts hunting for a signal... and your home provider will charge you "Pay As You Go" rates that are, let's be honest, insane!

By disabling roaming on your main line, you prevent those sneaky background charges. You can still use Wi-Fi, but you won’t be hit with a "Daily Roaming Pass" fee just because someone sent you a meme on WhatsApp.

  • Keep your main line for emergency SMS only -
  • Switch off the Data -
  • Save your money for the good stuff! -

2. eSIMs are the Absolute Game Changer!

If you’re still swapping out those tiny plastic SIM cards with a paperclip... stop! There’s a better way. An eSIM (Electronic SIM) allows you to download a data plan directly to your phone. No physical card needed!

At myesims.com, we offer coverage in 160+ countries with Activation in minutes. It’s literally: Buy -> Scan -> Connect. You get to keep your original number for WhatsApp & calls while using our 4G/5G speeds where available for everything else. Our plans are data-only service (no local phone number). It’s the Best Price! & Great Service! all in one... with near-local rates.

3. Check if your phone is "eSIM Compatible"

Before you get too excited... ensure your device is eSIM Compatible! Most modern iPhones (from the XS onwards), Samsung Galaxys (S20 onwards), & Google Pixels support this tech.

  • Pro Tip: Your phone also needs to be "Carrier Unlocked." If you’re on a contract where the phone isn't fully yours yet, check with your provider first! You can see more in our FAQs if you're unsure.

4. Planning your Data Needs in Advance

Don’t wait until you’re lost in a train station in Seoul to figure out your data... that’s a recipe for stress! Think about what you’ll be doing. Are you a heavy Instagrammer? Do you need Google Maps 24/7? Or are you just checking emails?

We have specific collections for every corner of the globe:

Plan now & activate in minutes!

5. Kill the "Data Vampires" (Background Apps)

Did you know your phone is constantly "talking" to servers even when it’s in your pocket? Apps like Facebook, TikTok, & even your Email are sucking up data in the background.

Before you fly, go into your settings and turn off "Background App Refresh." This ensures that data is only used when you actually have the app open. It’s a huge data-saving tip that keeps your Global eSIM lasting way longer!

6. Maps... But Make Them Offline!

We all love Google Maps... but it can be a data hog. Here’s a travel hack for you: Download your destination’s map for offline use while you’re still on your home Wi-Fi!

Once you’ve downloaded the area, your phone’s GPS will still work perfectly without using a single kilobyte of data. This is a lifesaver when you’re in areas with spotty signals or if you’re trying to stretch your data plan to the limit. Speeds and coverage vary by location.

7. Use "Low Data Mode"

Both iPhone & Android have a secret weapon: Low Data Mode (or Data Saver).

  • On iPhone: Settings > Cellular > Cellular Data Options > Data Mode > Low Data Mode.
  • On Android: Settings > Network & Internet > Data Saver.

This tells your phone to stop doing non-essential tasks like automatic photo syncing to iCloud or Google Photos. It’s perfect for when you’re on a travel data plan & want to be efficient!

8. Public Wi-Fi: Friend or Foe?

Free Wi-Fi at the airport or a cafe is great... but it’s often unencrypted & slow. Never, ever do your mobile banking on a public Wi-Fi network without a VPN!

This is another reason why having your own Private & Secure Data Plan is so much better. You have your own personal connection that isn't being shared with 200 other people at the airport gate. Safety first, right?

9. Ditch Traditional Calls for VoIP

International calling rates are... well, they're scary. Instead of dialing a standard phone number, use apps like WhatsApp, FaceTime, or Messenger.

These apps use very little data for voice calls & the quality is usually much better! Plus, you can stay in touch with you & your family back home for basically pennies. All our eSIM plans support these apps perfectly... no more $5-per-minute phone calls!

10. Regional Bundles are Your Best Friend!

Travelling to multiple countries? Don’t buy a separate SIM for every stop! That’s way too much work. We have amazing Regional Bundles that cover entire continents.

Crossing from Brazil to Argentina? Check our South America plans. Going from South Africa to Kenya? Our Africa bundles have you covered. It’s all about convenience & staying connected with ease!
