Frequently Asked Questions

Q. How can I check my data usage (balance) on my SIM?

You can check your data balance online through our App (iOS , Android, and Web).

Q. Can I use tethering (Personal Hotspot)?

Our SIM card does not prohibit tethering (Personal Hotspot), so it should work.

Q. What does standard speed mean? What's the speed?

It is the actual standard speed (not the theoretical figure) for travel SIM cards available on the market.

It's about 2 Mbps for both download and upload. It seems not that fast but fast enough for travel purposes. If you need faster speeds than that, we recommend you to rent our Pocket WiFi 4G or LTE plan .

Q. My device is not on your compatibility list. Does that mean it won't work with your SIM?

Not necessarily. As long as your device is fully unlocked, there is a possibility that it will work. If in case it does not work, we can provide you alternatives such as:

  1. Upgrade to any of our Pocket WiFi plans (the price difference will be charged).
  2. Provide our mobile router to use the SIM (the shipping fee will be charged).
