T-Mobile's prepaid SIM card activation kits, the gateway to starting new service on the carrier, are currently free along with free shipping from its online store. Historically the price of the SIMs have fluctuated in price pretty randomly, but for several months now you had to shell out $9.99 for a single SIM. That's not much to pay to start your service and get a little over $3 in account credit, but free is always better.
If you're in need of a new T-Mobile SIM — standard, micro or nano — for a prepaid line or just want to have a few backups laying around, head over to T-Mobile's online store and load up your cart. You'll be required to use a credit card to check out, but rest assured that the balance is $0.00 when you're all done.
