What is Roaming? A Beginner’s Guide Before Traveling

Traveling abroad has become common for the new generation—whether for tourism, work, or study. One of the most common questions is: What is roaming, and is it really necessary? This article explains roaming in simple terms, compares its pros and cons, and introduces VPN as a safer, more affordable alternative for those who want secure internet access at a controlled cost.✈️🌍

What is Roaming?

Many people have heard the term roaming and often wonder what is roaming when they see it in their phone settings. Roaming is the process of connecting your mobile network to a foreign service provider’s network, allowing you to make calls, send messages, and use the internet seamlessly even when you are in another country with your original SIM card.

Phone Roaming📱

This means using your existing mobile number to make and receive calls while abroad. The system connects your device to a partner network in the country you are visiting.

Data Roaming🌐

This allows you to access the internet abroad through your home provider’s partner network. The charges are billed back to your original mobile carrier, usually included in your regular phone bill.

How Does Roaming Work?

The way roaming works is quite simple. When you travel abroad and activate roaming, your phone will search for a partner network that collaborates with your current provider (such as AIS, TRUE, or DTAC). Once connected, all your activities calls, text messages, and internet usage—are routed through that foreign network but billed by your home provider. The charges are then added to your next mobile bill, along with your existing plan.

Advantages of Using Roaming✅

• Convenience – You can use your existing phone number right away.
• No need for extra devices – No requirement to buy a new SIM card or rent a Pocket WiFi.
• Great for business travelers – Ideal for those who need to stay connected with clients or colleagues abroad.

Disadvantages of Using Roaming❌

• High costs – Charges can be extremely expensive if you don’t subscribe to a roaming package in advance.
• Unexpected charges – Risk of accidentally leaving roaming on, which may cause your bill to skyrocket without you realizing it.
• Unstable internet speed – Connection quality depends heavily on the local network in the country you are visiting.

Is Roaming Different from an International SIM Card?

Many travelers often wonder whether they should use roaming or purchase an international SIM card instead. Let’s compare the two options.

Roaming vs International SIM Card

• Roaming: Lets you keep your existing number, but it’s more expensive.
• International SIM Card: Cheaper, but requires changing to a new number.

Roaming vs Pocket WiFi

• Roaming: Personal and easy to use, but daily costs are higher.
• Pocket WiFi: Can be shared across multiple devices and cheaper per day, but inconvenient to carry around.

Roaming vs VPN

• Roaming: Best if your priority is making and receiving calls.
• VPN (especially BullVPN): Ideal if you need secure, affordable internet access with global connectivity.

What is a VPN?🐮

What is a VPN? VPN (Virtual Private Network) is a technology that encrypts your data and reroutes your internet connection through servers in different countries. This allows you to browse the web as if you were physically located in that country.
