Boost Your iPhone Signal

iPhones are arguably the most popular mobile phone brand in the US. As of April 2024, there are just under a whopping 150 million active iPhone units, taking up 27.95% 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.

So, if you find yourself struggling to maintain calls, send texts, or use your data, an iPhone signal booster is exactly what you need. Whether at home, in the office, or on the go, they are your best bet at strengthening your connection where it matters. In this guide, we’ll cover why your iPhone has a bad connection and go over the best iPhone signal booster recommendations.

Why Does My iPhone Have Bad Signal?

Cell phone signals, similar to radio waves (the AM/FM kind), can be weakened by various factors before reaching cellular devices. Here are a few reasons why your iPhone may have poor reception:

  • Heavy Cellular Traffic: Heavy usage by a large number of users in your area can lead to slow data speeds and dropped calls.
  • Cell Tower Distance: The farther you are from a cell tower, the weaker the signal strength you'll receive. You can use this guide to find your nearest cell tower.
  • Building Materials: Walls and roofing made of metal, concrete, or low-emissivity glass can significantly block cell signals, reducing indoor coverage. Visit Materials that Hurt Cell Reception for a complete list.
  • Natural Barriers: Mountains, hills, and even dense trees can weaken signal strength and hinder your iPhone's reception.
  • Weather Conditions: Rain, humidity, and lightning can decrease iPhone reception.
  • Interference: Other electronic devices in your vicinity, overlapping signals from nearby towers, and electrical interference can disrupt your iPhone's ability to connect clearly.

Just How Poor Is My iPhone's Signal?

Signal bars do not paint an accurate picture of your connection strength. 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 its own interpretation.

A more accurate way to gauge signal strength is by looking at decibel-milliwatts (dBm). Cell phone signals, like radio waves, are measured in dBm, typically ranging from -50 dBm to -120 dBm. The closer you are to 0, the better your connection.

Signal Strength General Results
-50 to -79 dBm Considered great signal (4 to 5 bars)
-80 to -89 dBm Considered good signal (4 to 5 bars)
-90 to -99 dBm Considered average signal (2 to 3 bars)
-100 to -109 dBm Considered poor signal (1 to 2 bars)
-110 to -120 dBm Considered very poor signal (0 to 1 bar)

How to Boost iPhone Signal

90% of Americans own a cell phone and 72% of them experience frequent dropped calls and disconnected service. Doesn't matter if you own an older or the latest iPhone model, it’s frustratingly common. Just as a car needs gas to run, a strong signal is essential for a smooth mobile experience.

There are several things you can try to boost your iPhone signal, such as:

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

However, those troubleshooting tips usually provide temporary fixes. The best way to actually boost your iPhone signal is with a cell phone signal booster. They are crafted to take your outside cell signal, even if weak, amplify it, and rebroadcast it inside. Your iPhone will automatically pick up a more reliable signal, keeping you connected for work or play. Here are our best iPhone signal booster recommendations:

Not Sure Which Cell Phone Booster is Best for You?

How Does an iPhone Signal Booster Work, Exactly?

Signal boosters for iPhone get you better signals via three components:

  1. Outside Antenna: This acts as a receiver, capturing the faint cellular signal from the nearest cell tower.
  2. Amplifier (or Repeater): This component uses patented technology to amplify the captured weak signal, significantly boosting its strength.
  3. Inside Antenna: Once amplified, the signal is rebroadcast by the inside antenna, blanketing your desired area (home or office) with a stronger cellular signal. This means more bars on your iPhone and a more reliable connection.

Simply put, if there is any outside signal, a booster 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 an iPhone Signal Booster?

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

  • Eliminates Dropped Calls
  • Crystal Clear Voice Quality
  • Quickly Delivered Texts
  • Faster Uploads & Downloads (Streaming)
  • Reliable Connection
  • Improved Reception
  • Wider Coverage
  • Reduced Dead Zones
  • More Bars
  • Longer Battery Life

Can iPhone Signal Boosters Boost 5G Signals?

The majority of our cell phone signal boosters can boost some 5G frequencies, specifically low-band 5G. The SureCall SpeedLink 5G is the only booster we offer that enhances mid-band 5G, which provides greater speeds, lower latency, and higher capacity.

Do iPhone Cell Signal Boosters Work?

Yes. As long as there is a sliver of cellular signal outside, FCC-approved cell signal boosters really work. Read our case studies for real-world results.

Can a Cell Phone Booster Sticker or Apps Help Boost iPhone Signal?


We’ve tested cell phone signal booster stickers, and they do not work. As far as booster apps go, they do not actually boost signal. They can help smooth out performance making it appear as if your signal is stronger.

To actually boost your iPhone’s connection, we recommend a cell phone signal booster.

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 Nokia devices.
