After a brief absence, 99¢ T-Mobile prepaid SIMs are back! Now though 8/13/15, T-Mobile prepaid phone SIM kits are 99¢ on the T-Mobile USA Website when you use promo code SIM99 at checkout.
When they aren't on sale, T-Mobile SIMs are a ridiculous $15 each, so you might want to stock up now for future use.
The prepaid phone 3-in-1 SIM Starter Kits include a nano SIM with mini and micro adapters and an activation code. 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.
If you have a tablet or mobile broadband device, T-Mobile has an even better deal for you. Mobile broadband SIMs in your choice of mini, micro and nano sizes are FREE when you order from this T-Mobile Web page now though 8/13/15. These SIMs can be used to activate a tablet or hotspot on any T-Mobile Prepaid or postpaid Mobile Internet plan. They also let you activate a supported tablet on T-Mobile's Free Data for Life plan which comes with 200 MB of data per month absolutely free. The broadband SIMs do not include a prepaid activation code so they won't work for activating a phone on a T-Mobile prepaid plan.
Either type of SIM can be used as a replacement SIM for any T-Mobile account, postpaid or prepaid.
There's a limit 3 SIMs per per order and 5 SIMS over a period of 30 days.
