MicroCell service dead?

I have an original 3G microcell that I got back in 2010. I’ve had no issues and it’s been rock solid ever since. As of last week the 4 bars logo on it has just been flashing.

I cannot receive voicemails all it says is “Call Voicemail”

I have AT&T and no one can send me a voicemail. When I call voicemail it tells me to try calling a 10-digit phone number again and if I have a mailing box out the number in (which I don’t). If anyone knows how to fix this, please let me know, thank you!
