T-Mobile USA Prepaid SIMs on Sale for 99¢ Until 9/30

T-Mobile USA is having another SIM sale. Now through 9/30, prepaid SIMs are 99¢, instead of the usual $15, on the T-Mobile USA Website provided you use the promo code SIM99 at checkout. 

T-Mobile no longer sells individual SIMs in mini, micro and nano sizes online. Instead they offer 3-in-1 SIM Starter Kits which 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, 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.

Prepaid SIMs can also be used as replacement SIMs for any T-Mobile account, postpaid or prepaid. Just call T-Mobile support and ask them to switch your account to the new SIM.

There's a limit 3 SIMs per order and 5 SIMS over a period of 30 days.

I'm a little disappointed that T-Mobile has switched from selling individual SIMs in mini, micro and nano sizes to using adapters. The adapters T-Mobile is using are a new design with tiny clips to secure the SIM in the adapter. Hopefully they will work better than older adapters which have a history of damaging phones. Nonetheless, I recommend being very careful when using an adapter especially with phones where the SIM slides into a blind slot.

  1. Breaking people's old phones is a great way to get them to buy new ones.

    Otherwise, they'd have to competitively subsidize their prepaid phones (with no strings attached) ala Sprint.

    1. That $30 plan is only available at Walmart, it's a Walmart only deal.

    2. The $30 plan is also available online.

  3. How long do you have to activate the sims?

    1. There's an expiration date printed on the card the SIM is attached to. For SIMs I've purchased from T-Mobile the expiration date has been between one and two years in the future.
