I've had a Samsung S4 for 17 months. Back in May I had the SIM reader replaced and since then sending texts from home would time out (failed) on an intermittent basis. Lately the problem has gotten worse.
I can send and receive texts anywhere else. My phone is unlocked and when I use a different SIM card when travelling it works fine. I have talked to customer support many times and no solution has worked. Today the support person told me there must be dead zones in my home. The whole house must be a dead zone because I couldn't send from any room!
1) Got a new Fido SIM card - no difference
2) Factory reset through Samsung - no difference
3) Clear the Cache on Chrome often - no difference
4) Power down wait for 10 seconds and power up - no difference
