Where do they get those SIM cards sold on E-bay and claim to be preactivated and work in any unlocked phone?

Question

I'm under contract with T-mobile and thought it would be a good option to have a prepaid Sim card when I run out of minutes.T-mobile told me I can't use prepaid Sim cards unless I purchase a pre-pay plan.
Another question,can I use my regular Sim card if I purchase a prepaid phone/plan?

I just upgrated my plan and signed up for another 2 year contract.Do you mean I can switch to a prepaid plan withot paying a cancelation fee?

Answer 1

Just get a pre-paid plan....simple...

it works on any fone and u can keep ure old sim....just change plans.

Answer 2

Later yet.. i also pick 2 sim card with a similar huge type, a million admin a million consumer. at the same time as the admin telephone/sim its open the consumer its off. Why.. on the artwork I actual have a Godzila telephone, becouse i artwork with ciment/sand/water and if i bypass to city I actual ought to change the sim and the flash stress in the different telephone who seem somewhat extra acceptable. So definite ..i decide on 2 sim with similar huge type.
