| | Problem Using Socket Connection on AT&T network
Please Login to Remove!
I am trying to connect to a server over direct TCP. The connection string I am using ("socket://<IP-Address>:<port>;deviceside=true") works fine on verizon and T-mobile phones, but I am having problems on a telus bold 9700 with a&t SIM card (US). I am getting a CriticalIOException when I try to connect.
The details are:
Connection string: socket://<IP-Address>:<port>;deviceside=true;apn=bb.telus.com;T unnelAuthusername=null;TunnelAuthPassword=null
Critical tunnel failure
I have tried various prefixes of above connection string with and without username and password etc. Does anyone know what connection string should I use ? I have also tried apns 'proxy' and 'internet.com' that have been suggested elsewhere.
The adv. settings->TCP/IP ... shows APN string "bb.telus.com" and web browser seems to be working just fine.
