I will be traveling to Singapore and the Philippines. Can I use the card in these countries and what settings do I need to do?

Yes you can! You just need to do settings once and manually search and connect to the respective country's network when you arrive. However, we recommend using this SIM card in Japan or South Korea only as it is costly to use it in the other listed countries. Please check out other card options on our website if you are not going to Japan or South Korea.

If I finished using the 10GB high-speed data, will I still be able to surf the internet at a slower speed?

Yes you still can at a lower speed of 256kbps.

Can I use Whatsapp to chat and make calls with this card?

You certainly can. Using Whatsapp to call saves you money.

Is the data inside this card enough for my usage?

An average person consumes 4GB (4000MB) of data in a 15 days period. Much less if traveling overseas for leisure as most of the time will be spent looking at sceneries or participating in some form of outdoor activities.

What are the shipping rates and how long will it takes for my purchases to arrive?

Can I use this SIM card in a new phone?

Make sure you make at least 10 to 15 minutes calls and receive calls to unlock the phone so it can be used with overseas SIM cards.
