99¢ T-Mobile prepaid SIMs are back! Now though 7/30/15 all prepaid SIMs are 99¢ on the T-Mobile USA Website when you use promo code SIM99 at checkout. This deal pops up at least once every couple on months. When they aren't on sale, T-Mobile changes an outrageous $15 each for their SIMs so it pays to stock up while the sale is on.
There are two types of SIMs to choose from.

The activation code is required when activating a new line of service on any T-Mobile prepaid phone plan, including the $30/month 5 GB of data, unlimited messaging and 100 minutes plan, which is only available with new online activations.
Prepaid mobile broadband 3-in-1 SIMs are also on sale for a 99¢ with the SIM99 code. These SIMs can be used to activate a tablet or hotspot on any T-Mobile Prepaid Mobile Internet plan. They also let you activate a supported tablet on any T-Mobile Mobile Internet plan including the 200 MB/month free plan.
Either type of SIM can be used as a replacement SIM for any T-Mobile account, postpaid or prepaid.
