Some users who subscribed to their carrier’s caller ID features may be the first ones to complain about this problem. Although there were others who were complaining about not seeing caller’s number or name. There are a lot of factors that contribute to this problem and they are as follows:
Temporary device problem.
Your Service Provider does not provide caller ID information.
There is a network outage in your area affecting your service.
Caller Name ID application by your Provider is not functioning well.
Inconsistent network connection.
The mobile data is turned off in your device.
You need to update your software / firmware.
Online contacts syncing was disabled.
Contact information saved on your phone was incomplete.
There are two or more versions of the contact.
Step 1: Reboot your phone. The very first thing you should do when things like this happen is to reboot or soft-reset your phone to eliminate the possibility of a temporary device issue. Rebooting the phone would run all necessary services and features while turning off the ones that may conflict the core services. Soft-resetting would refresh the phone’s memory, discharging all possible static electricity stored in components. To soft-reset your phone, turn it off and take the battery out for 30 to 60 seconds. Replace the battery then turn the phone back on and see if the solves the problem.
Step 2: Call your service provider. Inquire about it because there could just be a network failure in your area and you’re affected by it. If you were using their name ID apps, make sure your account is still in good standing. Things like these can only be verified by calling to your provider’s hotline. So, calling and waiting on the line (which would most likely to happen) for a few minutes is worth it.
Step 3: Make sure you have good service. I couldn’t emphasize the importance of making sure your phone’s mobile data is turned on and that the device is receiving good service. Sometimes, we look for resolution to a problem when in fact, there is no problem at all. Turning on and off the mobile data would sometimes help.
Step 4: Make sure your contacts information are all correct. If you have to go through it one-by-one, then do it. Make sure there is no duplicate contact or if correct information was saved in your phone. Naturally, no information will be displayed if there is no information to be displayed in the first place.
Step 5: Update Name ID applications. There are two carriers I know that offer name ID applications, Verizon and T-Mobile. The former offer it for a price while the latter for free. This problem may occur when the app needed updating or when it’s not really functioning well. While a reboot may help make sure the service is running, you may need to clear its cache and data from time to time.
