I went abroad from Canada for two years, tried to park two numbers to Virgin on cheap prepaid (still paying 5-10$ just to hold a number). Well they fucked up credit card payments on both accounts, closed them after a couple of months and stole our numbers. So aggravating to go through the trouble of parking the numbers, paying perhaps 300$ and then the aggravation of trying unsuccessfully to get those numbers back, and the aggravation of trying to figure out which services use those numbers for 2FA.

Canadian telcos are basically a scam (and Virgin is now my top hated one, assholes).

2FA using phone numbers is idiotic.
