Adafruit now sells the TING SIM card, a 2G GSM SIM that works great with all FONAs, and has a great billing system as

well, where you only pay what you use!

If you don't want to use TING, there are dozens of T-Mobile resellers such as Walmart, SIMPLEMOBILE, etc! Just ask

the seller if its AT&T or T-Mobile network. If they get cagey just say your apartment has no AT&T coverage.

Some suggestions from FONA users!

I've had good luck using the FONA with a SIM from Walmart. Their 'Walmart Family Mobile' is a T-mobile reseller

and you can pick up the SIM starter in store pretty easily (https://adafru.it/dEi). The service isn't the cheapest, it's

$25 for the SIM and $30/month for unlimited talk+text or $40/month for unlimited talk+text+data but there's no

contract as its all prepaid -tdicola

Just want to let the Adafruit team know that it is possible to get pre-paided minutes on T-Mobile and its a pretty

good deal. I was paying $100 for 1000 minutes (10c a minute 20 a sms) over the course of the

year. (https://adafru.it/dEj) For me it in my usage came out to about $8 a month. Have found this is something that

you have to ask for at the store. No evidence in advertising or website -Paul B.

Telna has a good deal you may want to point people to for FONA. I used them for a previous GSM project and

they worked great. $20 per year, includes 1000 free txt messages and a bunch of other nice features.

(https://adafru.it/dEk)I had a lot more issues with T-Mobile (Their cards go inactive if not used in a month and you

have to call to reactivate) -Tyler C.

I pay 2 EUR (a bit less than $3 USD) for 2 hours, unlimited SMS and 50Mb of Data at

There are specialty "machine 2 machine" SIM sellers that have plans that are tuned for the short bursts of usage

used by these kinds of modules. Check out these guys (https://adafru.it/vQA) for example, you can choose data,

You do not need to bring in or show your FONA to the Cell Phone store. Just tell them you need a Mini SIM

for a GSM phone and it's at home.
