You need to call your provider or carrier and inquire about the current status of their transmission in your area. You may need to provide your complete and detailed address or location. In case there are outages, you will be advised to wait 24 hours or until the problem was resolved.
Your carrier is the most reliable source of information like outages, however, there is no guarantee you get the correct info at the specific you called. Having worked as a technical support for a wireless company, I know exactly what representatives would do. They will neither confirm nor deny possible outages.
During my tenure, I would do the same thing. Even if I can see on my tools that there is a possible outage, we would be advised to wait few hours before we could deliver our spiels about the on-going outage. But it is still worth to call your carrier and inquire about outages.
You will need these because without them, your phone will not be able to register to your carrier’s network, thus, it cannot get any service at all. There are times when one data is incorrect that your device could register to the network but can neither get data nor make / receive calls and text messages.
You may still have to call your carrier about your APN settings (also known as WAP Settings) to check whether the ones your phone currently have are correct. Here’s how you check them:
From the Home screen, tap the Menu key.
Tap Settings, and then Connections tab.
Tap More networks, then Mobile networks.
Tap Access Point Names.
You can edit existing APNs or simply create a new one (I would prefer the latter).
Here are the APNs of the popular carriers in the US:
APN type: <Leave in Blank> OR Internet+MMS (depending on software version)
Sprint APN Settings
Proxy:<Leave it Blank>
Username: <Leave it Blank>
Password: <Leave it Blank>
Server: Not set
MMSC: <Leave it Blank>
MMS Proxy: 220.127.116.11
MMS Port: <Leave it Blank>
Authentication type: not set
APN Type: default
APN protocol: IPv4
Majority of the subscribers think that when they subscribed for unlimited data plan they will be getting limitless data downloads. Carriers cap their data to make sure they can offer better services to millions of their subscribers. Every service provider or carrier in the U.S. has their own “fair use policy” that makes it legal for them to throttle down your service if their system detected you’ve gone beyond the cap.
For example, Straight Talk offers unlimited data plan for $45. This is what people know about and this is what the company uses in ads and marketing campaign. However, only very few know that when the customer used up 2.5GB of data, his data service will be throttled down to get 2G speeds for the remainder of the plan month.
The point is, if your service was good yesterday and you get a crappy one today even if you’re getting full bars of signal in your phone, you may have used up data beyond your cap. This answers the question of our readers who were complaining about slow browsing.
If your phone is under warranty, you need to bring it back to the store and have it checked if you’re sure the problem isn’t caused by any of the three factors previously mentioned. Hardware-related problems should not be taken lightly because they can potentially damage your phone plus the fact that you’re paying the service you couldn’t use.
If your phone is out of warranty already and you’re willing to take a risk, you could try to open your phone and physically it for anything abnormal especially the antenna cable’s connection. In the picture below, you white cable is the antenna and the circuit board at the end is secure by a screw. Loosen the screw a bit and check the other end to see if it’s still securely attached.
For those who think this is too risky, have the phone checked by a technician in your locality.
Software / Firmware Issue
For software-related issues, we have at least three options. But before doing any of the following, you need to make a backup of everything that is important in your phone like contacts, messages, pictures, videos, etc.
Factory Reset – most of the times, this procedure can fix problems like this but there’s no guarantee. You could performing this procedure via the Settings menu. If that doesn’t help, boot to recovery mode and perform the factory reset there.
Update – it may not be applicable most of the time but just in case there is an available update for your device, don’t hesitate to upgrade it. Connect to a stable Wi-Fi connection and check for updates via the Settings menu. Or, you can download Samsung KIES to your computer and check for updates there.
Manually Flash Firmware – if ever I suspect that some problems on my phone is firmware-related and that I’ve done every possible fix available but the problem persists, I will never hesitate to re-flash the firmware I’m using. Of course, this is not applicable to everyone especially those who have no experience flashing firmware to their phone. I included this for the reason that you may know someone who knows how to.
