Not sure what your timeline is but there is a feature called text to pay you could ask for access to that is meant for this situation were you don't have access to your toast managed network, it does still require an internet connection but it could just be any WIFI connection. Allows you to text a link to the customer to pay on their phone. https://central.toasttab.com/s/article/Using-Pay-at-a-Distance Other than that as others have mentioned you would need your toast router (assuming you are not self managed) and some internet connection to it like a cellular modem/router.
