Default 3g connection not working

Please Login to Remove!

I am now testing my app on the actual device (bold 4.6). My application will connect using wifi,


however I am struggling to get it to work using 3g. I assume 3g is a WAP2 connection, so I have tried the following,

connSuffix = ";deviceside=true;ConnectionUID=WAP2";

but this does not work, i.e. no connection gets made. I am doing checks in the following way,

public static String connType(){

        String connSuffix = "";                 

        if (DeviceInfo.isSimulator()) {
            connSuffix = "";
        } else if ( (WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED) &&
            RadioInfo.areWAFsSupported(RadioInfo.WAF_WLAN)) {
        } else {
            String uid = null;
            ServiceBook sb = ServiceBook.getSB();
            ServiceRecord[] records = sb.findRecordsByCid("WPTCP");
            for (int i = 0; i < records.length; i++) {
                if (records[i].isValid() && !records[i].isDisabled()) {
                    if (records[i].getUid() != null &&
                        records[i].getUid().length() != 0) {
                        if ((records[i].getUid().toLowerCase().indexOf("wptcp") != -1) &&
                            (records[i].getUid().toLowerCase().indexOf("wifi") == -1) &&
                            (records[i].getUid().toLowerCase().indexOf("mms") == -1)   ) {
                            uid = records[i].getUid();
            if (uid != null) {
                // WAP2 Connection
                connSuffix = ";ConnectionUID="+uid;
            } else {
                // error no connection available
                Dialog.alert("no suitable internet connection detected");
                connSuffix = ";deviceside=true;ConnectionUID=WAP2";
        return connSuffix;
I have noticed that when running on the device i get alert of "no suitable internet connection detected" so I am wondering how is it not detecting the other connection types?

I really need to get the application using a wap2 3g connection. Any help with this would be much appreciated!!!

Not all carriers support WAP2, or populate the service book with the WAP2 UID.

I think the first thing is to use CoverageInfo to determine if you have BES connectivity - this should be your first choice.

After that, try the WAP2.

If WAP2 fails, you'll need to fall back to WAP1 or direct TCP. Both of these require carrier-specific APN or Gateway information to be encoded in your URL parameters.
