This is a standard sized SIM card with 6 months of unlimited data-only use. Service for this SIM card provided from T-Mobile through SparkFun and works in any T-Mobile coverage area in the world! No contract, no credit check, no strings attached. This card is specifically meant for M2M (machine to machine) communication. It is not intended to be used in phones, tablets, or hot spots and will not work in those devices. Compatibility will vary by device. You get 1GB per month at full LTE speeds (once that 1GB limit has been reached you will be throttled). Each card will have activation requested when it ships. Activation can take 1-3 business days to process through T-Mobile.
To be completely honest with you, we are carrying this data-only SIM so that you can get up and running with your cellular development quickly and without having to go to your local phone store and try to explain why you need a data-only SIM for your tweeting cat door.
Note: Your shipping confirmation email indicates the start of your 6 month time period. There are no additional charges or contracts associated with this product. Please contact Customer Service if you have any questions about adding another 6 months of data time to the end of your current service period.

Although there is a phone number that gets associated with the card, this is only important as a source or destination of SMS (text) messages. There is NO voice service using these cards.
I’ve been using them in ZTE MF61 and MF64 mobile hotspots. (had to trim it down to fit MF64)
Although I initially used one in an old phone which supported hotspot and tethering, the phone eventually freaked out and would no longer cooperate. This was the phones fault as the same SIM worked fine in the above mentioned mobile hotspots.

I bought two M2M SIM for use with tracking devices. The SIM does not work on devices, (also did not work on the mobile phone), I attended the T-Mobile store in miami, US1, and the staff informed me that the SIM was not enabled and that I should contact SparkFun. Since then I have exchanged e-mails with the SparkFun, and SIM cards do not work! I would like to receive the $ 183.10 back, canceling the purchase.
Hi, I’m sorry for the confusion and frustration. I checked over your order history and you have in fact been activated. I would like to take a second and explain. These are considered “machine to machine” sim cards. They are not your standard mobile sim like you would buy at the Tmobile store. We have found that they will work in some devices, however not all cellular devices will operate on this card. When a mobile device doesn’t know how to operate using the sim, it will send you to an activation link or have you contact the Tmobile customer care to activate. This is a standard action of the phone and not of the SIM. Unfortunately this makes it appear that the card is not active.
I would imagine you are using the cards in a device that can not accept a machine to machine sim. In that case, we would be more than happy to help you with a return on the purchase. I do apologize that the items did not work for your application.
One more note on this subject. While these cards have been found to work in other countries, they may have troubles outside of the United States. We have had international customers respond with mixed success.
I tried this in a Samsung Hot Spot Pro (V100T) and it didn’t work; I talked with my brother who works at T-Mobile and he said this kind of SIM might not work in some devices. So I sold that on eBay and bought a Fona from Adafruit. It works great with that board! I setup Internet on my RPi and can also make calls and send SMS messages! Works great!

Frankly, I’d like my money back. The SIM card didn’t worked.
Hi, our records show that your card was activated and issued a valid phone numbers. For more information on what might be going wrong, please see my comments below in Member 641785’s review. I am contacting you directly to discuss your issue. Thank!
Was very straight forward. Just plug in and go. No set up required.
I’m on my second card and it has consistently worked great! 4G is excellent in NYC.
I am rating 4 stars because I wish there was a better option for purchasing the service on an ongoing basis rather than buying a new card every 6 months.
Both cards I purchased took at least a week for delivery to the east coast. It would arrive in 3 days via standard USPS first class mail in a regular envelope.
Used for 1 month and ticked ~678MB so far on the SIM. Other than the usual T-Mobile coverage shortage, this is by far the best data sim to get. Just want to know how to manually extend the service beyond 6 months by user.
To extend your service, please contact the Sparkfun customer support team. They can help you with this. Please do not contact Tmobile, they will not be able to assist you.
Pros: after a small cut here, and a small cut there.. i popped this into a spare Samsung S4 i had laying around to give it a trial run. After a few APN settings i was good as gold!
Cons: Speeds are TERRIBLE, i’m getting .12 down and .21 up
Overall: I’m in canada, maybe that’s the issue with the speeds. if you’re looking to use this to replace your crappy data plan, don’t waste the time or money… item also took close to 3 weeks to arrive.
I’m impressed it worked in the S4. These are Machine to Machine, not device to device cards, so the speed issue may be a bit of incompatibility with the SIM as they aren’t intended to be used in a phone.
Greetings from the Netherlands!
I purchased the SIM for a streaming video camera that is operated from outdoors. No problems at all.Obtains reception moments after turning on.
You just install the Sim (it does come in Micro Popout!) and it just works. No activation procedure or anything - just put it in and start using the data.
It’s on T-Mobile so coverage and speed are pretty good!
For machine to machine data I have been using the Adafruit Fona. This is the perfect SIM card for the application. The card fits right into the Fona; there is no need for an adapter. The phone number ends up with a Denver area code.
Its sad to hear that you have discontinued this product. It was extremely useful for canadian users as Canadian mobile companies boost up their data prices for no reason.. I fairly disappointed with the discontinuation of this program.. This was the only product that I liked about spark fun..
