Hello,

I have developed a modem application using SIM900 modules. The problem is that now i am trying to use 4G LTE sim card and i have not accomplished network registration. If i use a GSM/GPRS sim card it works. What it could be?

Thanks for your attention.

Ricardo
 

you should check if your module supports 4G.
First search on google yielded this module only supports GSM/GPRS (2G)
 
Sim900 does not seem to support 4G
