Nothing is more frustrating than your iPhone dropping calls, failing to send texts, or taking ages to load. The same applies to cellular-enabled iPads. If you’re looking to improve your iPhone or iPad’s cellular signal for work or play, you’ve come to the right place. There is no better way to do so than with an iPhone signal booster.

Many factors contribute to unreliable iPhone connectivity. iPhone signal boosters take your existing weak 5G/4G signals, boost their power, and deliver them directly to your Apple devices. No matter where you are, if there is a sliver of signal from your carrier, your iPhone or iPad will never struggle to stay connected. Read on for more information on iPhone signal boosting tips, tricks, and FAQs.

Why Does My iPhone Have Poor Cell Phone Signal?

Cell phone signals are radio waves, the AM/FM kind. Like all radio waves, they are easily disrupted by anything and everything. Common iPhone signal disrupters include:

  • Heavy Cellular Traffic – Cell towers have limited capacity. Congestion slows down your iPhone's data speeds to a crawl and causes calls to drop.
  • Cell Tower Distance – Cell signal can only travel so far. The farther away your iPhone is from your carrier’s cell tower, the weaker the signal it receives.
  • Building Material – Metal, concrete, brick, low-e glass, and other materials interfere with cell signals reaching your home, building, or vehicle. Thus, iPhone connectivity may suffer while indoors.
  • Natural Barriers – Trees, hills, mountains, and valleys degrade signal strength and quality. Available signal may be below average, resulting in poor iPhone performance.
  • Weather – Rain, humidity, lightning, and the like affect cell signal. During inclement weather, you may notice a decrease in iPhone reception.

How to IMPROVE iPhone Cell Phone Signal?

There are a few things to try:

  • Toggle Airplane Mode
  • WiFi Calling
  • Update Your iPhones iOS and Carrier Settings
  • Remove Your iPhone Case
  • Switch to 4G Only
  • Change Carriers
  • Upgrade Your iPhone

The #1 solution that has proven to constantly work is a signal booster for iPhones. They significantly mitigate iPhone connectivity issues for the iPhone 14, iPhone 13, iPhone 12...all the way back to the iPhone 4. The:

  • Outdoor antenna communicates with distant cell towers and fine-tunes received signal.
  • Coax cables help bypass troublesome building materials.
  • Amplifier significantly boosts the signal.
  • Indoor antenna(s) broadcast the boosted signal wherever you need it.

See here for a full breakdown of how signal boosters work.

What About 5G? Can iPhone Signal Boosters Boost iPhone 5G Signals?

Yes, but not the “good parts” of 5G. At least for now.

Most boosters on the market only boost 4G and LTE signals. However, there are some low-band 5G frequencies from certain carriers that operate on 4G spectrum. Signal boosters will boost those 5G signals. Performance will likely be similar to that of 4G.

Mid- and high-band 5G, frequencies ranging from 1 GHz to 39 GHz, are the “good parts” of 5G. Signal boosters are not equipped to handle those frequencies yet.

Can the *3370# Code Boost My iPhone Signal?

*3370# or #3370# is supposedly a code iPhone users can dial to boost their cell phone reception. Unfortunately, it doesn’t work. It’s actually a number sequence used to activate Enhanced Full Rate Codec, which improved sound quality for specific devices. The best way to boost your iPhone’s signal is with a cellular booster.

Do iPhone Signal Boosters Work?

iPhone signal boosters work anywhere cell signal is available, even if it’s only a sliver. They’ll enhance existing cell signal for your home, business, or vehicle from any carrier, not create it. All cellular devices within the booster's coverage footprint will receive a significant signal boost. That includes:

  • iPhone 14s
  • iPhone 13s
  • iPhone 12s
  • iPhone 11s
  • iPhone Xs
  • iPhone 8s
  • iPhone 7s
  • iPhone 6s
  • iPhone 5s
  • iPhone 4s
  • Cellular iPads
  • Cellular Apple Watches
  • Even Android Devices!

No more dropped calls, undelivered messages, or snail-like data speeds. Here is a short video proving cell phone boosters work:

As you can see, our customer's cellular reception significantly increased with the weBoost Home Complete. Signal strength improved from -119 dBm to -75 dBm. Generally, signal strength ranges from -50 dBm (perfect signal) to -120 dBm (no signal). The close you are to -50 dBm, the more reliable your connection.

Do iPhone Cellular Amplifiers Work with iPads?

iPhone signal boosters are not designed for just phones. They work with any device that has 5G, 4G, and LTE capabilities. That includes cellular enabled iPad Pros, iPad Airs, iPad Minis, and all iPad Generations that work with 5G/4G.

You’ll know your iPad has cellular capabilities if it takes a SIM card. If your iPad has an active data plan, cellular boosters will help keep your data running smoothly whenever you're away from WiFi. Signal boosters do not improve WiFi connectivity, though.

If you struggle with poor WiFi for your iPad, a cellular router can help you get a better connection anywhere you go. When paired with a signal booster, your connectivity experience increases.

What iPhone Signal Booster Should I Get?

There are a few questions you should ask yourself to find the best signal booster for your needs:

  • What type of iPhone booster do I need? Home or vehicle? Maybe both?
  • If for home, what is your desired coverage area? Are you looking to cover only one room, two rooms, or the whole house?
  • If for vehicle, what type of vehicle do you have? Car, truck, semi, RV, or camper?

Here are some recommendations to help you make the best decision:
