We want to switch our devices (Netbiters) to NEO SIMs and are informed the following specification is needed.  Does it sound compatible? "sim card will need to support 5-band 3G/UMTS (WCDMA/FDD): 800/850, 900, 1900, 2100 MHz Quad-band GSM/GPRS: 850, 900, 1800, 1900 MHz"

Hi Charles,

Thanks for the question. While compatibility with radio bands is primarily a function of the radio in your device, it is true that the SIM card needs to support those frequencies as well. If I understand your question, you need to confirm the device is compatible with those bands. 

Neo SIM cards support both 3G UMTS and 2G GPRS technologies and frequencies and should be compatible with your devices.

Regards,
Bob

Further inquiry on device compatibility:

We have replaced the SIM cards that came with our field devices (Netbiter) with Aeris 2G/3G cards and have been successful for most sites. A few have not worked well. The original OEM SIMS did work and this is the compatibility info from them:

"The netbiter is not supported by the Verizon network. The modem on the Netbiter is GSM 3g with support for 3G/UMTS (WCDMA/FDD): 800/850, 900, 1900, 2100 MHz

In the united states you should be able to use AT&T or T-Mobile for main operators."

I'm thinking this is a frequency issue? We have tried both ATT and T-Mobile SIMS from Aeris and are successful with that most of the time but not always.

Thanks for any advice you can offer.
