I bought my phone in June of 2015 and up until about January of this year, I had been receiving texts and phone calls like one should. Now suddenly I'm not receiving any texts ( or if I do, they're days or weeks late)and some calls do not come through without being blocked callers, and i have issues dialing out to a few contacts.none of whom have koodo. My bill has been paid in full and it is incredibly infuriating. I'm not sure why i have this issue. is it a device or a carrier issue?? please help!!
