Hey @Hersheylorraine,
We can totally understand the importance of having a phone that works properly! In this case, we'd need to confirm some information with you so we can run through some basic troubleshooting steps.
- Can you confirm if you've had the chance to turn the phone off and back on again and then test your calls?
- How many signal bars do you see on your device when these calls drop?
- Did you notice if this happens only in one specific area, or is it pretty much anywhere you're located?
Let us know.
