Caller ID May Not Work When Roaming

SUMMARY: Your cell phone may not transmit caller ID information when you roam outside your normal network.

While roaming, when calling people from your cell phone, don't be surprised if they don't always pick up their phone. Depending on your cell phone carrier and your current location, your phone number may not appear on the recipient's caller ID. Instead their caller ID may just list "Unknown Number" or "000-000-0000", prompting many to not answer your call.
