Adafruit is now a phone company :)  Or, well, we've sold DIY cell phones for awhile now but you've never been able to buy your FONA and a SIM Card all in one place.  Now, with these GSM Sim Cards from Ting, you can turn your FONA project into a working cell phone with just your maker skills and a visit to their website.

WARNING: Ting works on the T-Mobile 2G GSM network which is shutting down in the USA over the course of 2020 and beyond, so please be aware these are not for long term usage and may not work in your region.

You may not be able to activate these SIM cards for the 2G network, please call TING on the phone rather than using the online account creation as they will not let new 2G accounts activate online.

We do not recommend 2G anymore for USA usage!

Ting's an alternative cell phone provider who thinks the experience at companies like Verizon or T-Mobile is too impersonal and too complicated. Another good reason to go with Ting is rather than pay for a plan up front, you simply pay for what you use.  So let's say you have your FONA set up so that your mailbox will call you every time you get mail - but you don't get any mail for an entire month - you won't be charged for the calls you're not making.  We think it's the perfect provider for IoT, DIY cellular projects, and a great alternative to standard carriers.

Right now these SIM cards are only for sale to USA customer addresses. These SIM cards are completely unactivated, you need to activate it with a credit card once you receive it (but it's super easy, we activated ours in about 4 minutes). No extra service or 'minutes' come with the SIM - once activated you will be billed for the voice/data/text messages you send plus the device, at the very reasonable rates All billing goes through Ting, Adafruit is only selling the SIM card itself!

These cards are one-number use only so once your phone number's associated with it, you can't change it.  They are relatively inexpensive, however, so aren't a bad option if you want a multitude of phone numbers.

With the Ting online account dashboard and the official Ting app, they give you the tools you need to take complete control of your account, your usage, and ultimately, your bill.

Technical Details

​Dimensions of SIM Card: 25mm x 15mm / 1.0" x 0.6" You can snap the card apart into standard, mini, micro and nano SIM sizes.

Note: While the packaging you receive may slightly differ from our photos, the sim card will be functionally the same!

Update: The Ting SIM card is now compatible with 3G, LTE and 5G
