My iPhone 7 Plus Goes Straight To Voicemail! Here’s Why & The Fix.

When your iPhone connects to a Wi-Fi or Bluetooth device for the first time, it saves information about how to connect to that network or device. If something changes with that process, it may cause connectivity issues.

Deep software problems, especially with network settings, can be difficult to track down. Rather than trying to track an issue down, we’re going to reset all network settings and give your iPhone a fresh start.

1. Open the Settings app.
2. Tap General.
3. Scroll down and tap Transfer Or Reset iPhone.
4. Tap Reset.
5. Tap Reset Network Settings.
6. Enter your passcode if prompted.
7. Your iPhone will shut down, reset, and turn itself on again when the reset is complete.

Sometimes when your iPhone experiences issues related to your cellular network (no or poor service, calls going straight to voicemail), the problem is stemming from the cellular network, not the iPhone itself.

Below are the support numbers of major wireless carriers to contact if you’re experiencing problems.

1. Verizon: 1-(800)-922-0204
2. Sprint: 1-(888)-211-4727
3. AT&T: 1-(800)-331-0500
4. T-Mobile: 1-(877)-746-0909

The UpPhone recommend that you update carrier settings immediately after they become available because outdated settings may lead to connectivity issues between your iPhone and your wireless carrier’s network.

Some potential issues include having poor service or your iPhone going straight to voicemail anytime you receive a call.

1. Make sure that your iPhone is connected to a Wi-Fi network, or that Cellular Data is turned on.
2. Open the Settings app.
3. Make Tap General.
4. Tap About.
5. After a few seconds, if a carrier settings update is available, you’ll see a pop-up on the screen of your iPhone which says, “New settings are available. Would you like to update them now?”
6. Tap Update.

You can use iTunes to perform iOS updates on your iPhone. If you’re unable to update your iPhone in the Settings app, sometimes using iTunes to update your iPhone is a simple workaround.

1. Plug your iPhone into your computer using a Lightning cable (charging cable).
2. Open iTunes.
3. In the upper left hand corner of iTunes, click the iPhone icon. 
4. In the top box underneath iPhone, click Check For Update.
5. If an update is available, click Update.
6. Keep your iPhone plugged into your computer while the update downloads and installs.

When your iPhone is in Airplane mode, both Wi-Fi and cellular connections turn off and you won’t be able to receive calls or text messages.

There are two ways to turn off Airplane mode:

A DFU restore has the potential to fix software problems by completely erasing the code which may be causing your problem. The code is rewritten as if your iPhone is brand new, so the software problem may get solved.

Think of it like a house that has cracks in the foundation. Rather than try and fix the cracks, we are building an entirely new foundation.

If you can, back up your iPhone before completing a DFU restore. Any time you do a restore, it erases everything from your iPhone. However, after the restore is completed, you restore all your backed up data back onto your iPhone.
