Selecting appropriate hardware

I am in the process of designing a product that requires data communication over the cellular network.  I need to do everything I can to keep hardware costs down.  I am looking at Simcom SIM800 and SIM900 modules. Almost all of the off-the-shelf SIM800 modules require a Micro (3FF) SIM, and it's my understanding that Aeris only supplies Mini (2FF) SIMS.  Is this correct?

Some of the SIM900 modules support the Mini (2FF) SIMS.  These modules come in dual and quad band versions.  Which frequencies does Aeris use?  Do I need the quad band radio?

Are there any other low-cost radio modules that are known to be compatible with the Aeris network that you could recommend?  

Thanks for any guidance on this.

Hi Rick,

Let me answer your first question regarding SIM form factors. Yes, you are correct, the Aeris SIM is available in different grades (standard and industrial) but both in mini-SIM (2FF) form factor. Please see http://neo.aeris.com/aeris-sim-cards/ for details. 

I will let others answer your questions regarding hardware. 

All the best.

Hi Rick,

We also offer micro SIMs (3FF) form factor on through Digi-Key.  You can get them at this location:

http://www.digikey.com/product-search/en?keywords=aeris%20sim 

For 2G we use 1900MHz Band 2 which should be compatible with either the SIMComm SIM800 or SIM900 offerings.

Thanks,
Dean

Thank you!!! Having micro SIMs available is a game changer! Knowing the frequency band is VERY helpful too.
