I had my Samsung Galaxy Ace phone from Koodo less than a month ago. This morning when I tried to call my friend it says not registered on a network. I tried to pull the battery and sim out but it did nothing. I asked my friend to call my number but it goes directly to my Voicemail. I just couldn't use my phone. What can I do?
Make sure the phone didn't accidentally get set to 2g or GSM only in the network settings. Also make sure that you didn't accidentally turn on airplane mode, press and hold the power button like you were going to turn the phone off and when the options come up make sure where it says airplane mode that it doesn't say on. If it does say on tap it to turn it off.
