When app shows offline, then need to set up the apn 
Firstly, Need to ask the carrier about the apn informtaion and mccmnc of the sim card in watch 
Then send those two command: pw,123456,apn,apn name,user name,password,MCCMNC#(don't need to write the username and password if it is blank)
pw,123456,ip,54.153.6.9,8001#

For Example: if you use the card Speedtalk 
Apn name :apn,wholesale
Apn username:blank 
the command: pw,123456,apn,wholesale,,,31026#
pw,123456,ip,54.153.6.9,8001#

If you use the card T-mobile:
Apn name:epc.tmobile.com
Apn username:blank
Apn password:blank
The command:pw,123456,ip,54.153.6.9,8001#
pw,123456,apn,epc.tmobile.com,,,31026#

Note:When your watch requires you to enter the PIN code, the watch does not have a keyboard to enter your password, so you must call the operator of the SIM card on the watch to ask you to cancel the PIN code.< br>
