If you check your detailed MetroPCS call history (now Metro by T-Mobile) online and notice frequent entries with the number 123 or 123 GSM, it is a source of common confusion for many customers.
The number 123 in your MetroPCS call history almost always indicates that a call was made to access the voicemail service on that line. Dialing 1 or *123 is the standard, internal shortcut used by many mobile providers, including Metro by T-Mobile, to connect the user directly to their voice mailbox.
This article provides a clear breakdown of the 123 entry, explains the meaning of related terms like GSM and GSVO, and guides you on how to check your complete call history.
Decoding the “123” Entry on Your Metro Log
The short, three-digit code 123 is a unique number reserved by the carrier for an essential, internal service.
- Voicemail Access
The primary and most widely confirmed purpose of the 123 entry in your MetroPCS call history is to log Voicemail Access.
- Outgoing Call to 123: This log entry records every time the user dialed 1 or *123 to listen to or manage messages in their voice mailbox. The duration of the call corresponds to how long the user spent listening to the prompts or messages.
- The Meaning of “GSM” and “GSVO”
Sometimes the entry is followed by technical acronyms, which are simply metadata about how the call was routed.
- 123 GSM: GSM stands for Global System for Mobile Communications, the digital technology that T-Mobile (and thus Metro) uses for its network. When 123 is paired with GSM, it confirms the voicemail access call was routed over the standard GSM voice network.
- 123 GSVO: The acronym GSVO is less common but is a strong indicator of Google Service Video Out or Google Services Voice Over. When a call log shows an entry like 123 GSVO or just GSVO paired with another number, users often report that this indicates:
- A video call placed using a service like Google Meet or Google Duo.
- A call or message placed through a third-party calling app to conceal the final number or utilize data/Wi-Fi instead of the standard carrier minutes.
How to Access Your Full MetroPCS Call History
The 123 entry will only appear in the detailed usage logs provided by Metro by T-Mobile (My Account). To see your complete history and put the “123” calls into context, follow these steps:
- Log into My Account: Go to the official Metro by T-Mobile website and log into your My Account portal using your phone number and Account PIN.
- Access Account History: Navigate to the My Account menu and select “Account History” or “Check Usage.”
- View Call History: Select the desired line, and click “Call History.”
- Review the Period: You can review the past 90 days of activity. The 123 entries will be interspersed with regular outgoing calls and may appear as part of your overall call volume.
Note on Incoming Calls
It is important to remember that most Metro by T-Mobile prepaid plans do not provide detailed records of incoming call numbers in the online logs. You will only see the incoming call logged with the time and duration, which often leads users to mistake these blank entries for suspicious activity.
Frequently Asked Questions (FAQ)
Could the 123 entry be a forwarded call or a secret text?
No. 123 is a fixed code reserved for the voicemail system. It is not a secret individual’s number, nor does it typically log text message content (only the log of a text message, if recorded, would appear). If you see long durations associated with the 123 number, it means the user was listening to or managing their voicemail for that period.
If I see 123 entries in the call history, does it mean the user is deleting their voicemails?
Not necessarily, but it can. The 123 entry logs any interaction with the voicemail system, including checking for new messages, listening to old messages, deleting messages, or re-recording a greeting. Any of these actions would generate a duration associated with the 123 entry.
Why do some calls show GSVO instead of a regular number?
The GSVO (Google Service Video/Voice Out) label is strongly linked to calls initiated outside of the standard cellular dialer, such as those made using Google Meet, Facebook Messenger, or other third-party communication apps. These apps use data (Wi-Fi or cellular data) to complete the call, but the carrier still records the activity using a system code like GSVO or 123 because the call is routed through their infrastructure.
Conclusion
The presence of 123 or 123 GSM in your MetroPCS call history is almost always a benign and expected log entry that confirms voicemail access on that specific line. While Metro’s call logs can be confusing due to the lack of incoming number details and the use of technical codes like GSVO, the 123 number is a straightforward indicator that the user was checking their messages.
