what can i do for the error ?

Hi,

Can you please try to create TCP client using WIPSOFT commands(using same APN USER and PASSWORD) and check if client is created or not ? In case of failure please enable the CME ERROR and check what is the exact CME ERROR number received(to analyze the cause of failure i.e. host unreachable).

Thanks.

i see , the ISP has problem …ha ha ha
