so last year all together i bought probably around $400 worth of bitcoin at bitcoin depot atms. i always stayed under $250 per transaction because then you only need to put your phone number to verify. since then i have got a new phone # on a different carrier, tonight when i tried to buy some btc and put my new number in the atm it pretty much said because this is a VOIP number (which it is not) it can't be used. although ive read that some actual VOIP number will work, so im confused. what should i do?
