Data roaming was first invented in the 2000s. Ever since, getting connected overseas has become simpler than ever - but it comes at a literal cost.
This guide will go into what data roaming is and all the important things you need to know, so you can enjoy your travels without breaking the bank.
What Is Data Roaming?
Data roaming refers to an action when you are connected to any other network besides your primary network. This mostly happens when you are overseas (each country has their own local network) but can also sometimes occur within your own country.
How Does Data Roaming Work?
When you step outside of your network coverage, your phone automatically searches for compatible networks. Once it connects to one, your carrier negotiates access behind the scenes. Charges are typically based on how much data you use, and they can add up quickly - especially if you're engaging in data-heavy activities like streaming and cloud storage.
What Is International Data Roaming?
International data roaming refers to using mobile services abroad. Your device connects to foreign networks through agreements your home carrier has established, enabling continued service while traveling.
What Is Domestic Data Roaming?
It is the opposite of international data roaming. Domestic data roaming happens when your phone connects to a different network within your home country, usually due to limited coverage from your primary carrier in certain areas.
What is Cellular Data Roaming?
Cellular data roaming is the use of mobile data services when your device is connected to a network other than your home carrier's, either domestically or internationally. It is a synonym to data roaming and is the standard naming convention on some devices' settings.
What Does Data Roaming Do?
Data roaming allows your mobile device to connect to networks outside your primary carrier's coverage area. This ensures you can access the internet, send texts, and make calls while traveling. However, using data roaming can lead to additional charges, especially when abroad, as your carrier may impose higher rates for data usage on foreign networks.
When Should Data Roaming be On?
You should enable data roaming when traveling outside your carrier's coverage area and need continuous access to mobile services. This is particularly useful for international trips where staying connected is essential. However, be aware that data roaming can incur significant charges, so it's advisable to check your carrier's roaming policies and consider purchasing an international plan or using an eSIM to manage costs effectively.
Is Data Roaming Good?
It depends on what you value. There are a few things that you need to consider like the extra charges and convenience that comes with it. If you don't mind the additional fees, data roaming is arguably the easiest way to having internet access. Having this arrangement with your primary carrier could also help when you accidentally enter an area where their network isn't available.
Data Roaming on iPhone and Android
Whether you use an iPhone or Android, turning data roaming on or off is easy:
On iPhone:
- Go to Settings
- Tap Cellular or Mobile Data
- Tap Cellular Data Options
- Toggle Data Roaming on or off
On Android:
- Go to Settings
- Tap Network & Internet
- Tap Mobile Network
- Toggle Data Roaming on or off
We also recommend reviewing your current period roaming data (iPhone users can find this under Cellular settings) to understand your usage before traveling.
How Much is Data Roaming?
Each carrier has their own pricing plans, but typically, international data roaming costs a lot more than domestic data roaming. In fact, some local carriers have a mutual agreement to support one another's customers at little to no cost (though rarely).
Roaming charges vary depending on:
- Your mobile carrier
- The country you’re visiting
- Your data consumption
Even a few minutes of social media or a photo/video upload can cost several dollars without a plan in place. Carriers like AT&T, T-Mobile, and Verizon offer international data packages, but these aren’t always the most affordable.
The Smarter Solution: Use an eSIM
A more flexible and cost-effective option is using an eSIM. Instead of relying on your carrier's roaming agreements, eSIMs let you purchase local or international data plans digitally - no physical SIM card swap required.
With Eskimo’s global eSIM, you can:
- Connect instantly upon landing
- Choose from local, regional, or global plans
- Avoid excessive roaming charges (prepaid)
- Manage everything directly from our app
It’s ideal for travelers who need reliable, affordable data abroad.
Postpaid vs. Prepaid Data Roaming
Just like your normal mobile plans, data roaming can also be postpaid and prepaid depending on the carrier.
When to choose postpaid
Having the postpaid option means that you can rest assured that you will always have connectivity. However, the postpaid option tends to lead to excessive data roaming usage, leading to substantially more expensive (and unexpected) bill at the end.
When to choose prepaid
If you want to manage your budget strictly. You know how much you'll spend - and as long as you use your data roaming within limits, you 100% won't pay more than what you plan to.
How to Avoid High Data Roaming Charges
Here are some practical tips to save on roaming costs:
- Disable data roaming in your settings when not in use
- Use Wi-Fi whenever possible
- Download offline maps and travel guides
- Consider a local SIM or a flexible eSIM plan
- Check with your carrier for international add-ons or daily passes
Should You Keep Data Roaming On or Off?
If you're relying on a traditional carrier and don't have an international plan, it's safest to keep data roaming off. Not only will it save you from shocking roaming bills, it also helps to conserve battery life. But if you’re using an eSIM like Eskimo, enabling roaming lets you tap into local networks without the sky-high rates.
