Since I signed up with Koodo, I've had very lousy cell service. Sometimes people go straight to my voice mail. Sometimes they get nothing happening when they call. Text messages come 2-3 hours late sometimes, while other times they are instant. When experiencing call problems, if a person texts me, they can then call me. And sometimes they need to call me to be able to text me. These are all at times when I have very good cell signal. It's not my phone either, because it worked just fine on rogers network.
