How do I activate a SIM device with my phone number?
I tried to activate the SIM device online but then it assigned a new number so I had to cancel it. I don't want to reactivate service because I'm concerned that it will only activate a lost phone. My husband won't let me use his phone because it recognizes his number and uses his account. I can't call to 611 or anywhere. I do not have access to any other phone during the work day.

This sounds like prepaid. To activate a prepaid SIM card with an existing number, you need to call. If you activate online, you will get a new number assigned.
