iPhone Signal Boosters: How to Boost Your Signal

Written By SignalBoosters
25th May 2023

iPhones are arguably the most popular mobile phone brand in the US. As of May 2023 there are just under a whopping 150 million active iPhone units, taking up 30.4% of the market share across the 50 states. That's all very well, but if your iPhone can’t get cell reception, then it's about as useful as a paperweight.

To make sure that your iPhone runs at is best in weak signal areas, you need a cell phone signal booster. These neat devices give the best chance at strong reception by boosting the signal outside your home, office, or vehicle.

Why Does My iPhone Have Bad Signal?

Cellular signals are radio waves, just like the AM/FM kind. Before they reach your iPhone, they can run afoul of all sorts of issues. Here are a few reasons why your iPhone may have poor reception.

  • Heavy cellular traffic: Congestion from high user volumes slows down data speeds and causes dropped calls.
  • Cell tower distance: Signal strength weakens as you move farther away from the carrier's tower.
  • Building materials: Materials like metal, concrete, and low-e glass interfere with cell signals indoors.
  • Natural barriers: Trees, hills, and valleys degrade signal strength, resulting in poor performance.
  • Weather conditions: Rain, humidity, and lightning can decrease iPhone reception.
  • Interference: Other devices, overlapping signals, and electrical interference disrupt cell signals.

How Do I Get Better Signal on My iPhone?

There are good practices to improve cell phone reception.But when comes down to the best option, it's a no-brainer: a cell phone signal booster.

90% of the Americans own a cell phone and 72% of them experience frequent dropped calls and disconnected service. Doesn't matter if you own an iPhone 6, 20, or whatever. Like an expensive car without gasoline. No matter how nice it looks or powerful it runs, without a drop of gas, it's stationery. No signal to your phone means you've got an expensive music player and calculator.

This isn't what you're paying your monthly bills for.

A cell phone signal booster is an FCC-certified device that takes weak cell signal, amplifies it, and rebroadcasts the signal to an area in need inside a home or car.

A cell phone signal booster is an FCC-certified device that takes weak cell signal, amplifies it, and rebroadcasts the signal to an area in need inside a home or car. 

Signal boosters work with all and 4G LTE networks on all iPhones and other smartphones, too. They work on all carriers (AT&T, Verizon, T-Mobile, and many more). All voice traffic is currently over 4G. 5G handles only data. Where 5G is not available data is transferred using 4G. Cell signal boosters will boost all 4G LTE and currently some 5G frequencies. They are one-time investments with no monthly fees, nor do they need landline broadband internet to work.

Do Those Cell Phone Booster Stickers or Apps Work?

No.

Repeat after me: No.

Putting an Apple logo sticker on a Dell doesn't make it a MacBook. Using a sticker or an app will not magically get you better signal. This is not a smartphone issue. This is about getting stronger incoming signal from the cell tower.

Will the “Secret” *3370# Code Boost My iPhone Signal?

The rumor goes that if you type *3370# or #3370# into your iPhone’s keypad your signal will improve. Unfortunately, it is just that, a rumor. There are no secret codes that magically improve cell reception. The rumored codes are number sequences used to activate Enhanced Full Rate Codec for better sound quality on certain devices.

How Does a Cell Phone Signal Booster Work, Exactly?

Cell signal boosters get you better signals via three components:

  1. The Outside Antenna pulls in your existing poor celluar signal.
  2. The Amplifier (or Repeater) boosts cell signal with patented technology.
  3. The Inside Antenna rebroadcasts the enhanced signal to an area in need. More bars to you.

Simply put, if there is any outside signal, a booster kit will amplify that signal and broadcast it throughout your home or office. The two main caveats are that it must be indoors, and there must be at least a sliver of signal outside. We wrote a comprehensive blog on how a signal booster works if you'd like a more detailed explanation, but if not, know that they will improve the reliability of your iPhone's signal.

What Are the Benefits of Signal Boosters?

The obvious benefit of installing a cellular amplifier is better reception. Aside from that you will enjoy whole bunch of extra advantages:

  1. Eliminates dropped calls
  2. Crystal clear voice quality
  3. Quickly delivered texts
  4. Faster uploads & downloads (streaming)
  5. Reliable connection
  6. Improved reception
  7. Wider coverage
  8. Reduced dead zones
  9. More bars
  10. Longer battery life

Just How Poor is My iPhone's Signal?

Believe it or not, there's no industry standard for cell phone bars. What is 1 bar or dot on Verizon might be 3 bars on AT&T, 2 or full bars on T-Mobile despite receiving the exact same signal and downloading and uploading at the exact same speeds. Each carrier has their own interpretation.

However, cell phone signals are accurately measured in decibel (dB) reading. Cell phone signals are radio waves (the AM/FM kind) and operate at a frequency of -50 to -110 dB. -50 dB is great signal, full bars. -110 dB is poor signal, a near dead zone.

How Do I Get Better Signal On My iPhone?

There are several ways to improve your signal, but the best is still a cell signal amplifier. That being said, you can try:

  1. Toggle Airplane Mode
  2. WiFi Calling
  3. Update Your iPhones iOS and Carrier Settings
  4. Remove Your iPhone Case
  5. Switch to 4G Only
  6. Change Carriers
  7. Upgrade Your iPhone

We wrote a blog about how to improve your cell signal overall. Whatever you choose, a good outside antenna, an inside antenna, decent cabling and of course a strong cell signal booster will undoubtedly give you super cell signal reception boost. Our kits do just that!

What is included in a Cell Phone Signal Kit?

All iPhone signal booster kits are sold with everything you need to get better signal. They include:

  • An outdoor antenna communicates with faraway cell towers and refines the received signal.
  • Coaxial cables help bypass obstructive building materials.
  • An amplifier greatly enhances the signal.
  • Indoor antenna(s) then broadcast the amplified signal to provide improved coverage wherever needed.

Can iPhone Signal Boosters Boost iPhone 5G Signals

Kind of. 5G signal boosters boost certain 5G frequencies that operate on the 4G spectrum. Mostly these are the lower bands which don’t have great data speeds. Mid- and high-band 5G, frequencies ranging from 1 GHz to 39 GHz, are the “good parts” of 5G. Currently a cell phone signal booster for an iPhone won’t increase your data speeds dramatically.

That’s not to say they never will. Although the odds of that happening soon are pretty slim. Most likely it will take several years for cell signal boosters to be able to boost 5G.

Do iPhone Cell Signal Boosters Work?

Yes. Real, FCC approved cell signal boosters or amplifiers work, if there is outside signal. We wrote a whole article on how and why cell phone signal boosters work. In fact, you can even get some amazing boosters for your car, truck or even boat. Good iPhone cell boosters will work with all apple devices that use cell signal, like iPads or even Macs if they take a SIM card. It will boost reception for any cellular device, across all US carriers (depending on the booster chosen).
