android - アプリがサーバーからhttp応答を取得できなかったのはなぜですか？それは妻とは機能しますが、3Gでは機能しませんか？

Question

着信電話番号を投稿して応答を取得し、トーストを使用して画面に結果を表示するアプリを作成しようとしています。エミュレーターと電話で妻と一緒に動作しますが、3Gでは動作しません。通話が終了すると、トーストは結果を表示します。すでにAPNをインターネットに変更しましたが、機能しません。3Gでこれを行う方法はありますか？

BroadCastReceiver

             String response=client.login5(incomingNumber,hash);
            JSONObject jObject = new JSONObject(response);
        resusername = jObject.getString("name");
         reshash = jObject.getString("hash");
