I recently switched to Koodo. I unlocked my phone, service worked great for one day, then I lost service. I no longer can send or receive data or even make a phone call. The only time I can use the internet occurs when I am connected to wifi...but still no phone or texting ability. I have tried the battery, factory settings, and even replaced my sim card. The phone identifies itself on koodo...but not really. Why do I not have network services anymore? My phone is a Samsung Galaxy S3.
