Where's that? I can only find $50, $60 and $70 plans:

Go here: http://prepaid-phones.t-mobile.com/sim-card. Check your device, and once you know which SIM type you need, click the "Add to Cart" under "Phone".

I literally just did this, so the timing of this post is nice. Even more nice is that they are waiving the $10 SIM card fee right now.

You buy the actual plan after you get the SIM and activate it. I don't know what they charge for activation, if at all.

So it's not available to current T-Mobile customers unless you want to change your number, then?

Move your number to Google voice

Then you can use your unlimited data for calls (if I'm not mistaken)

I used switching to that t-mobile plan as an opportunity to set up google voice. At least now I can cover future number changes.

Port out to another prepaid, then back in.

It's listed on this page (about 2/3rds of the way down):

I believe you have to buy the SIM card and then go to this page to pick your plan:

They sell it through wal*mart

Look at "Which plan is right for you" on their pre-paid site: http://prepaid-phones.t-mobile.com/prepaid-plans

I wrote about how to get it.

You have a typo, "100 minutes of text".

Unlimited 2G data. LTE is limited to 5GB per month. I've hit their throttle before, and while it's nice that you don't go dark, it's not for normal use.

Not many people can use 5GB of data in a month. I'd say "normal" use is nowhere near 5GB.

5Gb on a handset without tethering isn't "normal" use, even with LTE...

It depends. 1.5 hours of facetime will use ~1gb, and streaming 1 hour of music every day will run at 1gb over the month. Add browsing during commute and you're getting close. It's probably not "normal" in the sense of average, but for the heavy consumer, they will have to moderate their usage.

It's not 4G though... If you want 4G, it's at least $50, $60 or more for more data.

Not true, I have the $30 plan with a Nexus 5 I bought from the Google Play store. I get 4G LTE speeds no problem.

I'm on the verge of doing the exact same thing. On that plan are you able to use any of that data for tethering or mobile hotspot? A customer service rep said you can use all of your "up to 5GB" 4G data for tethering if you want, but I found that a little hard to believe.

Tethering is not officially allowed, you have to spend another $15/month for it.

It's possible to tether anyway, but YMMV - it's through workarounds like using only HTTPS, setting up a VPN, or changing your desktop user agent.
