Can I use KnowRoaming for data and my normal cell provider for voice?

*This article is only compatible with the KnowRoaming Global SIM Sticker.

Just like a dual SIM phone can only have one SIM card active, your phone will only be able to use either your Home SIM card or your KnowRoaming SIM Sticker for all network services (calls, data,) at a time.

The KnowRoaming sticker is itself a SIM card, so when you arrive abroad, the KnowRoaming sticker automatically detects a foreign network and switches you onto KnowRoaming.

For more information please contact the 24/7 KnowRoaming Support Team at: or 1-888-357-7347
