How to Find Out if Your iPhone 7 or iPhone 7 Plus Model Has Faster or Slower LTE
To determine whether you have the Qualcomm modem or Intel, you need to find your iPhone 7 or iPhone 7 Plus model number. It’s buried in Settings.
Step 1. First open that up and go to General settings.
Step 2. Tap About at the top.
Step 3. Then scroll all the way down and tap Legal.
Step 4. Lastly, tap Regulatory.
At the very top in small print you should see your model number. If your model number is A1660 or A1661, you have the faster Qualcomm modem. If your model number is A1778 or A1784, you have the slower Intel modem. Sorry to potentially ruin your day.
