Things to note when using SIM cards in Europe

Data communications overseas can incur expensive roaming charges. There are plans that limit data volume or that throttle speeds when a certain amount is exceeded, so it is important to check the details of your plan before traveling.

3. Check the size

When traveling abroad, you must choose a SIM card that is the right size for your smartphone. If you are purchasing a SIM card locally, be sure to check the size of your smartphone's SIM card slot before purchasing.

4. Activation may take a long time

Activating a SIM card can take time. If you purchased a SIM card locally, it may take several hours to activate, so plan accordingly.

If your smartphone is locked, you may not be able to use the SIM card locally. Please unlock it or use an unlocked device.
