I followed dicecuber's advice and called 911. I was told that this was done by the NSA.
Now things seem to be peaceful. No more calls from my known-but-unknown friend. I now have 6 voicemail like that though. Wasted about 30 minutes to listen to those voicemail, and I'm using T-Mobile $30 100-minute plan.
I thought of the possibility of an app on my phone doing this and am considering doing a factory reset, but I'm not sure if it's even possible for an app to do that. Not to mention I believe I don't have any malicious apps on my device.
- If I do a firmware restore would I need to calibrate the battery?
- Do you add an "s" after "voicemail" to make it plural?
For those that are wondering, this is absolutely not a trolling post nor a joke.
