Hi! I would like to use my graphene os phone without a sim card - I understand I could use it on Wi-Fi and pairing a dumb phone to signal which could be one option. But for another option someone told me that instead of using a dumb phone to pair it with signal where I would need a sim for the dumb phone - instead I could get a phone number online without the need of a sim card? Could someone please recommend me the place where I could do this - I don't mind if it charges a fee - but I would like to not use a sim and have a number to send a receive calls and have reception in USA. Thank you very much for all of your help and support!
