Hi every one! I'm soo excited to have wp 8.1 in my Samsung ativ s from TELUS in Canada but its use on Roger mobility. Once the update was done this morning. The connection is horrific on the device now, I called Rogers reset the network from their end, I input the apn settings in the phone and nothing is working,connection jumps from LTE to 2g,3g and a lot of the times there is no connection.I'm very frustrated about this I have tried just about everything even resetting the phone. Has any body experience this problem?
