T-Mobile-to-go phones

[Den26]

I have a T-Mobile prepaid phone, which uses a SIM card. Is there any way to duplicate the SIM card, place it in a different T-Mobile phone, and share the phone number? The wife & I use the phone very little, so it's not worth having 2 different phone numbers. Thoughts?

Sorry - it's not technically possible.
Even if you cloned a SIM, most of the networks would lock it almost immediately after seeing it registered twice.
It is possible for one phone number to ring two cellphones, but AFAIK it's not a part of any standard T-Mobile package, especially bottom shelf to-go one.
