I use Dark Star and I cannot make or receive calls

• First things first, please check whether you have sufficient minutes in your plan.

• Your service may be interrupted if your plan has expired. Please make sure you have a valid plan when making a call.

• Please make sure the SIM card is inserted correctly into your device.

• Please make sure the number you’re dialing or receiving calls from is not in your block list.

If you still can’t make or receive calls after going through the first checklist, this guide will help you out:

1. Go to Settings > Cellular / Mobile Data> Cellular Data Options / Mobile Data Options.

2. Check Roaming - Make sure all roaming options are turned OFF.
