What is Data Roaming?

Data roaming refers to the ability to access mobile data services while traveling outside of your home network’s coverage area. When you use your mobile device to access the internet, send messages, or make calls while roaming, you’re essentially connecting to a foreign network, which can result in additional charges.

How Does Data Roaming Work in Cambodia?

In Cambodia, data roaming works similarly to other countries. When you arrive in Cambodia with your mobile device, it will automatically connect to a local network provider’s signal. This network provider will then charge your home carrier for the data you consume while roaming, and your home carrier will pass these charges on to you, often at a premium rate.

Are There Any Special Things About Data Roaming in Cambodia?

Cambodia has a relatively well-developed mobile network infrastructure, with several major network providers offering coverage across the country. However, it’s important to note that data roaming charges in Cambodia can be quite high, especially if you’re not aware of the applicable rates and don’t take the necessary precautions.

The cost of data roaming in Cambodia can vary greatly depending on your home network provider and the plan you’re subscribed to. Generally, you can expect to pay anywhere from $10 to $20 per day while roaming. This can quickly add up, making it essential to explore alternative options or be mindful of your data usage.

While you can use your home carrier’s international roaming plan, it’s generally more expensive than purchasing a local SIM card or eSIM. International roaming plans often come with higher data rates and additional fees, making them less cost-effective for extended stays or heavy data usage.

Can I use my eSIM or local SIM card in other countries besides Cambodia?

eSIMs and local SIM cards are typically country-specific. If you plan to travel to multiple countries, you may need to purchase separate eSIMs or local SIM cards for each destination.
