The 4 Booster Manufacturers:

Update the phone's preferred roaming list. CDMA phones have a list of carriers and towers in the phone that tells the phone what towers it can use while roaming. Search Glass x. Video of the Day. Brought to you by Techwalla. References Cell Reception: How To: Photo Credits. The closer to dBm, the worse the signal. However, the number of bars on your phone are subjective to the phone manufacturer and carrier. But dBm readings are not subjective. Just plain math and truth.

So how do you find dBm reading on your smartphone? The next best method is performing a speed test around areas inside and outside your home. Field test mode on Android varies by phone model and Android OS version. However, it is generally found under the Settings menu. Once you have your dBm reading through field test mode or app, walk around inside and outside the perimeter of your home.

Make note which areas get the best dBm reading. This shows you the general direction of your cell tower and which rooms inside your home have the best reception. Find cell tower maps and understand cellular signal strength beyond bars. The great thing about cellular or radio frequency waves? They can reach miles in the distance to deliver calls, texts, emails, and internet you need. Almost anything between your phone and the cell site can disrupt your signal.

Cell towers have the ability to transmit signal for tens of miles, which is necessary in the countryside. Literally anything under the sun can absorb or disrupt cell signals: Building material and the layout of your house is the leading cause of poor indoor cell phone signal coverage. The biggest culprit is metal. Anything metal—roof, wall, studs, lining, etc.

Other disruptors are low-e energy-efficient glass, concrete, wood, and other signal-blocking material. Open floor plans generally have better signal than multi-room layouts. Thick walls are a major impediment. Electronics can create RF interference. Same with anything metal again!

These are the smartphones with the best signal strength

Moisture can affect your signal. So rain, snow, and thunderstorms are fair game. Even solar flares have some effect. It feels as if windy days can blow signal to or away from you. Just remember this, less things between your cell phone and the cell tower, the easier the two can keep communicating. Cellular signals are very fickle by nature.

FYI, phones older than years tend to have degraded batteries and components, so that might affect performance.

13 Best Ways to Boost Your Cell Phone Signal

Helps limit battery drain on your phone. A little improvement for better reception. They were a crucial part of the device that gathered and sent signals to the cell tower. However, on most smartphones today, the antenna is now designed to be tucked inside the phone. Great for cosmetic reasons but difficult for increased reception, because those interior antennas still need to do the same job.

By holding your phone in landscape position sideways , your hands may be effectively blocking your antenna from the cell tower.

How the tests were carried out.

Although the newer smartphones have designs to combat this problem, a smartphone in a rugged case and gripped with both hands can occasionally give you the no-signal burp. To avoid such antenna problems, try holding your phone in an upright position with your antenna free of a blockage. It should help increase the flow of signal. An unblocked cell phone antenna is vital for any phone.

Tower congestion is a real pain at concerts, festivals, and crowded public events. With so many people on their smartphones and tablets, it's bound to overwhelm the cell tower or cell site. It all leads to the following problems:.

    Instead of competing for signal bandwidth and clogging up the network, finding a less populated area should help improve your situation. Of course, if you followed Step 5 above, you already know how to find the nearest cell towers. Good for lone wolves. May involve some walking. If your smartphone is about years old or newer, you can skip this part. But for those still hanging onto your Blackberry, Windows Phone, Palm, flip phones, brick phones, etc. Phones, like people, get old. And technology is changing, meaning newer phones support newer technology that may have that reliable coverage and fast internet you need.

    The LG V40 Has the Best Cellular Reception of Any Phone |

    Should make a difference for much older phones. Costly unless provided free by carrier. If your phone is fully paid for or past its two-year contract, it may be time to jump ship and find a carrier better suited to fulfill your mobile needs. And most carriers are eager to get customers to switch, so you might be able to get a new or highly discounted smartphone or bill. For example: Even US Cellular provides deals to switch. If a cheap and simple cellular plan is the goal, Google Fi uses a mixture of carrier networks and secure wifi hotspots to deliver service.

    We recommend using the Open Signal app to research carrier heatmap services for your location. Search by ZIP code and compare network rankings in your area. With that information along with understanding cell tower location, it should give you much better ability to assess the quality of your carrier's and competition's services.

    Perhaps talk and text is more important to you than internet data, so T-Mobile's or Sprint's plans might be more cost effective. No longer paying for deadbeat service. Forget terrestrial-based internet. Look to the skies. Speeds are also slower compared to landline and cellular internet. May be only option in unserved or rural areas.

    Expensive with higher lag and slower speeds than terrestrial-internet. DIY hacks and homemade antennas may slightly help, but you risk damaging your phone. Keep reading. Closer to dBm is good signal. Or, at least, it should be. Whether you make lots of calls or just scroll through your Instagram feed, staying online with your carrier's LTE network is absolutely critical.

    How we came up with this list:

    And while this year's flagship phones all perform pretty well at that basic task, the LG V40 takes the crown as the best. We've been working with Cellular Insights for a few years now to periodically test the RF reception on each year's leading smartphones, as those tests require specialized lab equipment we don't have in PC Labs. For this year's RF testing, we included a whole bunch of recent phones. All of the Android phones we tested this year have Qualcomm's new X20 modem, which promises up to 1. On paper, that's superior to the Intel XMM in today's iPhones, which offers speeds of up to a gigabit.

    Curious about previous test results? The X20 allows for 12 data streams of Mbps each. We're looking for sensitivity as the signal fades, not the absolute maximum speed that can be pumped through a modem. The CMWFlexx can simulate pretty much any signal condition you can think of, including arcane band combinations, signal handoffs, and even 5G.

    It's used by both handset makers and wireless carriers to test and verify their phones. For most levels of signal, there isn't a huge difference between this year's premium smartphones. Putting five models on this chart makes it a bit hard to read; the major takeaway is that the OnePlus 6T is a notch slower than more expensive phones with very good signal, but recovers in weak-signal conditions. In the brutal world of modem manufacturer bragging rights, Qualcomm stays in the lead, but just barely.
