When you use your phone abroad, you are beyond the reach of your home network and your phone has to connect to foreign networks instead. This is known as roaming.
Using foreign networks often involves paying an additional fee, called the roaming charge.
The cost of this charge changes from country to country, but a general rule is that the further you are from home, the more expensive it is to use your phone.
Roaming charges are applied when you use your phone to call, text or access the internet. They can also be applied when you receive a call or text, which means you’ll be paying for both sides of a conversation.
At the end of each month, any roaming charges you have accumulated will be added to your phone bill.
