I recently invested my hard earned money into a galaxy s4 after breaking it off with my blackberry curve. I've rarely ever had issues with my curve in regards to receiving phone calls and text msgs on time, whereas my s4 constantly (every day actually..) receives some texts later than they were sent to me. This also happens with phone calls and anyone calling me is directed straight to voicemail, even when i have full bars of connection and a fully charged battery! I've called koodo technical support but they seem to be of no help. Both times i've called they've asked me to hang up and do a battery and sim card pull while they push some updates.. which does not help at all as the problem persists literally hours later. I haven't had this issue with the blackberry curve cause i've been living in the same area so I know I have good connection here, but for some reason this phone doesn't receive my texts and calls on time. What do I do?
