anybody used one of these outdoors in sunlight? how readable is it? also is it usable in cold temperatures? esp. compared to LCD or other LED displays.

well … why has it taken so long?! Finally! a wifi module to add to small projects that doesn’t cost more than the all the other components! This breaks some barriers.

Got my SIM today. Inserted it in an old 3G Gobi/Qualcomm Netbook and got it to connect by using APN=epc.tmobile.com (AT+CGDCONT=…)
Don’t know what the “official” APN to use is … SparkFun?
Haven’t tried any speedtest.net, but probably I couldn’t help answer what T-Mobile 4G really is, since I don’t have a 4G/LTE device (modem, router, etc), and I’m not sure what T-Mobile actually advertises in this coverage area.
Thank you SparkFun and TMobile! … Just ordered one.
(I’m hopeful (hint.hint) that just maybe sparkFun is cooking something up to offer a reasonably priced cellular hardware+service package that is easily integrated into uC-sized pacakges, and could be a feed to phant.io (sparkFun’s “cloud” data service) or my own back-end.)
I have soooo many projects that need wireless (cellular) remote data transfer, but they’re low volume (100s of units), low-priced ($100s devices), low data volume (<50MB) and speed requirements… hard to justify the cellular data transfer when the cost of comms.hardware is 10x more than the cost of the device itself, and then to add $50/month service per device … I can’t sell that.
Looking at your available cellular module SM5100B and BoB too pricey at ~$120 and from comments seems a bit iffy. Why can’t there be an offering in the $50 range, small, simple, and stable availability (10+ year lifecycle). And then add a reasonably priced (<$10/mon) service plan from the carrier (T-Mobile/ AT&T / VZW) … only need 3G or less speeds, and low volume (<50 MB per month) … why pay for 10GB??? $50/mon?
Enabling the smaller embedded sensors with cellular service, will drive the Internet of Things (IoT) … (billions of devices/sensors sending data)
No public wish lists :(
