iPhone 14 Pro Signal Issues

I have an iPhone 14Pro and the signal is not as good as my iPhone 12 that I use for another line. I have noticed this in several states and almost all locations. Any suggestions?

This same issue comes up every time a new iPhone is released, and it occurs for the same reason:


Cellular carriers need to properly optimize their towers and antennas for the latest cellular frequencies.


When it comes to 5G, the iPhone 12 supports the following frequency bands:


  • 5G NR (Bands n1, n2, n3, n5, n7, n8, n12, n20, n25, n28, n38, n40, n41, n66, n71, n77, n78, n79)
  • 5G NR mmWave (Bands n260, n261)


The iPhone 14 Pro supports the following frequency bands (differences from iPhone 12 in bold):


  • 5G NR (Bands n1, n2, n3, n5, n7, n8, n12, n14, n20, n25, n26, n28, n29, n30, n38, n40, n41, n48, n53, n66, n70, n71, n77, n78 n79)
  • 5G NR mmWave (Bands n258, n260, n261)


When a cell phone connects to a cell tower, it tells the tower "Hi, I'm this kind of phone, and I support these frequency bands."


The tower says "Great, let's see what's least congested… OK, use frequency band (as an example) n48."


If the cellular tower isn't properly adjusted/optimized for the assigned frequency band (again as an example) n48, your iPhone 14 Pro may see little to no signal where your iPhone 12 on frequency band n28 sees full bars.


If the tower assigned your iPhone 14 Pro to use band n28 as well, everything would work as it did before, but because the newer frequencies are most likely to be less crowded, that probably won't happen.


Long story short, contact your cellular provider, only they can fix this.

Then you may want to have your device examined.

The 13 Pro Max and 14 Pro Max have been the best iPhones I've owned in terms of reception; there is an area near me where calls always used to drop and they haven't there on the 13/14 Pro Max despite the area still having a single bar of signal and no changes being made to the tower that serves the area.

My iPhone 14 max pro has virtually no reception in my house. We have 3 other 5g iPhones in the house (12, 13 pro, and 13 pro max) all of which have a strong signal and no dropped call issues.

The 14 also seems to have issues with Wi-Fi calls too, so I’ve had to revert to zoom calls on my laptop. My cellular provider is Verizon

As stated numerous times above, this shows your provider's local cell tower is at fault, as you are almost certainly not using the same cellular frequencies between the two phones.


Your network provider needs to properly tune their local cell towers or program their base station controllers not to assign devices to those frequencies until they get a chance to tune them.


I realize it's frustrating, but one way to prove this to yourself is to use your device several miles away when it's communicating with a different cell tower and you will quite likely find your reception is different (perhaps better, perhaps worse.)

i have the same issue in canada. i switched to a iphone 14 pro from note 20 ultra and i get only 1 bar vs 5 on my samsung. with exact same sim card. weird thing is sometimes it goes up to 4 bars without touching the phone . 90% of the time though it’s at 1 bar 5G or 2 LTE. my carrier blames apple since my samsung phone has no issues on 5G or LTE.

Again, you can't make that assumption.


For example, looking at the LTE tech specs for the two phones:


iPhone 12 Pro Max:


  • FDD‑LTE (Bands 1, 2, 3, 4, 5, 7, 8, 12, 13, 14, 17, 18, 19, 20, 25, 26, 28, 29, 30, 32, 66, 71)
  • TD‑LTE (Bands 34, 38, 39, 40, 41, 42, 46, 48)


iPhone 14 Pro Max (differences emboldened):


  • FDD-LTE (Bands 1, 2, 3, 4, 5, 7, 8, 12, 13, 14, 17, 18, 19, 20, 25, 26, 28, 29, 30, 32, 66, 71)
  • TD-LTE (Bands 34, 38, 39, 40, 41, 42, 46, 48, 53)


What this shows is that if your iPhone 14 is assigned to TD-LTE band 53, you will see an entirely different signal profile than anything you would ever see on the 12, as the 12 didn't support it.


Unfortunately there is no easy way for consumers to find out which band their device is assigned to as carriers don't generally want customers to have that information.

They have.


They have no control over carriers or whether they properly configure their towers.


I have explained why what you see is likely a local tower issue and how you can probably verify it for yourself simply by driving ten or fifteen miles away so you are using a different tower.


There's nothing for Apple to figure out here; their devices are fully tested and work properly with properly functioning cellular networks.

This issue should be resolved by apple with an os update that shuts off the problematic frequencies. Resort to the same frequency list the last generation of phones worked off of until and unless the towers are optimized. Putting the entire blame on the carriers is ignoring the fact that the device is designed to connect to a frequency that is known to be a problem and will likely continue to be a problem for a long time. Tmobile, iphone 14 pro, 1 bar lte only no 5g.

Apple cannot legally or technically block specific frequencies. And to do so would mean that you would have no service if you traveled through an area that used those bands instead of your current local bands.


How would you suggest that Apple identify “problematic” frequencies? They will only be problematic in a specific area. I have T-Mobile, iPhone 14 pro, and I get a 5Guc (millimeter band) connection, and 300-500 mbps almost everywhere I travel. If your “problematic” frequencies were arbitrarily shut off by Apple I would have no service at all.


I suggest you contact T-Mobile for suggestions.

@Dog cow-Mof The problem with your perspective is that a mobile artefact does not exist in an isolated bubble, rather it is part of a digital ecosystem. It’s not up to the environment to reconfigure itself to adapt, but rather, the artefact itself must be able to function in the environment with which it is deployed. Telling us to go and talk to our Telcos and asking them to reconfigure their systems so this particular handset works is not practical. Every other handset manages ok. I just got a new Samsung and it works perfectly. This would indeed seem to be an Apple problem.
