Connecting to AT&T

I'm testing out a tracking device which connects with 3G at gsm 1900 Mhz. Am I understanding correctly that these 2G/3G sims will not connect to AT&T on this frequency. I get the feeling I am only connecting to T-mobile as the coverage is very spotty. Would using the LTE/3G sim make a difference?

Hi Frank,

Thank you for posting your request on the community support, only LTE SIMS are serviced by AT&T. If you are using GSM Global SIM then it is serviced by T-mobile. GSM and LTE coverage will depend on the device location. The coverage map can be viewed on the following link:

Also, you will need to use AT&T certified devices. 
Kind regards,
NEO Support Team

Thanks for the reply.  I understand that the GSM network is T-Mobile but the problem I'm having ) and I think a lot of other by having read through these posts) is, I don't believe I'm getting 3G coverage through T-Mobile, only 2G. Does my receiver need to receive in 1700Mhz AND 1900Mhz to get 3G through T-mobile or is just 1900Mhz acceptable? And what about WCDMA or UMTS @ 2100Mhz? Will this not connect to anything on the network?
