Hi,
do you want to use the intrenal TCP/IP stack on the HL8548 or external?
How do you want to manage the HL8584? Windows, Linux or µC?

Hi

After inserted SIM to your module you can use: AT+KSRAT= to select radio access Where mode is <1,2,3,4>
1 2G only
2 3G only
3 Search for 2G first
4 Search for 3G first

After that check your network registration by AT+CREG=? If response return +CREG: ,1…That mean your device connected to network.

Next Add pdp context by : AT+CGDCONT=[[,<PDP_type>[,[,<PDP_addr>[,<d_comp>[,<h_comp>]]]]]]

Finally check IP that network provide by: AT+CGDCONT=?
