What is Data Roaming? Should I Turn It On While Traveling + Best Alternative?

Data roaming enables you to use mobile internet services when traveling outside your home network area. Without data roaming enabled, your smartphone would have limited connectivity abroad. 

In this guide, we will explain in detail about what is data roaming, how it works, roaming rates, and most importantly, the best alternative to roaming.

I. Understanding Roaming – What is Data Roaming?

Roaming or data roaming is the capability of using your cellphone to connect to the Internet in places where your home network operator does not support. For travelers, this happens when you travel abroad. 

When your phone cannot find your usual network, it roams to find another one. 

Roaming allows you to call, text and use data as you normally would, but it can cost more.

The ability for a cell phone to roam in a certain country depends on the agreement between the operators of each country. 

What is a roaming plan?

Roaming plan allows you to use your cell phone abroad for a daily fee. This daily charge includes an allowance for calls, texts and data. On a roaming plan, you act as a guest operating on a foreign network. 

Insight: All big cell phone companies have deals with other networks so that their customers can still use their phones in places where their major network does not cover. 

II. How Does Roaming Work?

Roaming on a cell phone is as simple as the practice of switching on and off. But, behind that practice, there is more to get to know.

Roaming is divided into many types based on different criteria.

Based on coverage, there are 03 types of roaming : 

  • Land coverage roaming: allow people to use cell phones on land.
  • Maritime coverage roaming: allow people on ferry, cruise ship or boat to use cell phone
  • Air coverage roaming: allow people to connect during a flight

The most used roaming type is land coverage roaming. This service is set as default on cell phones.

Based on region, there are domestic/regional and international data roaming:

  • Domestic/regional roaming: allows you to use your cell phone and other mobile devices in locations within your country where your current carrier does not have coverage. They partner with other network carriers to provide Internet access across the country. 
  • International roaming: similar to domestic roaming, but allows you to use your cell phone and other mobile devices outside your home country or region on a foreign network.

Note: There is a policy of “roam like home” in Europe but it is a good idea to check roaming costs at your destination prior to traveling to avoid any unexpected costs.

Pro Tip: Using Virtual Private Network (VPN) Services for Data Roaming

III. How Much Does Roaming Cost? Roaming Rates

How much does data roaming cost - roaming rates

Cost of domestic roaming has largely been eliminated because many carriers, especially major ones now cover the whole country, even larger regions.

However, international roaming is totally different.

When roaming internationally, you are charged for each service you use

The roaming rates are determined by many factors, including the network carrier you choose, the country you visit, and the services you use. 

For example:

  • If you travel abroad and you want to make calls, you need to use voice roaming service.
  • If you want to use mobile data to browse the web, you need to use a data roaming service.

Nowadays, travelers majorly use data roaming because with mobile data, you can make calls, send text messages via apps, and get Internet access as well.

Normally, you will expect to pay more for consuming data outside the country. So you must be careful and attentive; otherwise, you may end up paying high fees for the services you use while overseas. 

To help you have an overview about data roaming rates in the world, here we gather some rates of big network carriers in different destinations:

Based on the table above, we can conclude that roaming rates are different by destination and plan type.

Need to know about roaming:

  • Roaming plans are set by default on your phone.
  • You can activate/deactivate data roaming from your phone’s settings

  • If you forget to turn off data roaming, you will have to pay unexpected fees. 


IV. Roaming Zones – What You Need to Know

Roaming zones are set up between mobile carriers to simplify roaming arrangements and pricing. 

There are major roaming zones which have standardized costs for roaming services (calls, SMS, and data consumption). Within a zone, roaming rates are much lower compared to outside the zone.

Here is an overview of common roaming zones and the countries within each zone: 

Roaming zonesCountries

Note: The exact list of countries in a roaming zone can vary by provider. 

Important Note: Some network operators like O2 UK or Rogers Canada allow customers to check roaming services available by country.

In addition to the general steps above, consider these things when activating data roaming on your phone:

  • Contact carrier to confirm roaming is enabled. Most have it activated by default, but check for sure.
  • Enable international roaming data package. Some carriers require users to buy an international roaming package before using data abroad. Confirm the costs and data limits as well.
  • Enable Data Roaming Guard if any to limit mobile data use to avoid high bills.
  • Test with a web page or speed test.
  • Manually select a carrier if needed.
  • Disable roaming when back home to avoid roaming fees domestically.

VI. Should Data Roaming be On or Off?

Take these considerations to decide to toggle on or off your data roaming:

  • Location: If you travel abroad and do not have an international roaming package, it is recommended to turn off data roaming to avoid high roaming charges.
  • Roaming charges: Check the rates for roaming of your current mobile network operators.
  • Essentiality: If your phone is carrier-locked and you need continuous access to data services while maintaining contacts on your primary phone number to make calls/SMSs, keep roaming on. But if your phone is unlocked and eSIM-equipped, you can think of using an international eSIM which still allows you to use mobile data to access the Internet while keeping your primary phone number. This is much cheaper than roaming.
  • Wi-Fi availability: If you are in the area with reliable WiFi connection, you can turn off data roaming and use WiFi instead.

When in doubt, it is best to keep data roaming off. Just turn it on when you need, and make sure that you always control and manage your data usage and costs if turning it on.

VII. Data Roaming with an International eSIM – How Does it Work?

Data roaming with an international esim

eSIM is a virtual SIM card already installed into your smartphones. eSIMs function just like the physical SIM cards used for cellular service.

Only the latest generation of smartphones are equipped with an eSIM

People can add an eSIM plan to their cell phone by scanning a QR code. 

There are 2 common types of eSIM plan: eSIM plan with data only and eSIM plan with data + voice/text.

Using an eSIM with data specified for a certain country or region, you do not need to pay expensive roaming fees. 

You can buy eSIM from either mobile network operators with eSIM services or eSIM providers like Gigago. 

VIII. Data Roaming Plan vs. Data eSIM Plan: Which Option to Choose?

You can use an eSIM or a roaming plan to stay connected. But, which one is better?

Your home mobile network operator may offer you data roaming services while you travel, but the fees can be high and there is likely to be limitations on what you can do with data roaming. 

Data eSIM, on the other hand, gives you a chance to enjoy lower costs with better flexibility.
