4. Can I use the sim card with my wifi router?
The unlimited data SIM card can be used with your own portable wifi router. However, additional processing is required in order for the SIM card to work properly with wifi routers like changing the APN settings. These settings and functionality of each wifi router vary per device so the telecom staff cannot assist you with updating these settings. If you are able to setup the wifi router yourself after retrieval of the SIM card, then the SIM card can be used. If you are unsure how to process these changes, we do not recommend you purchase this SIM card for use with a wifi router.
