8 Effective Ways to Boost Your Cellphone Signal

Derek Walsh 09-09-2016

We’ve all been there. You need to make a call but you can’t find a signal, or you can’t have a proper conversation because it keeps cutting out. While our cellphones mean that we’re all more in touch than ever before, the devices and the network they use don’t always work as well as they should. What can you do to improve things?


Why You Have Trouble Getting a Signal

Your cellphone uses radio waves to connect to a cell tower, which sends it over a network to another tower and ultimately to another phone. Ideally, these cell towers would all be the same distance apart, comfortably within the transmission range of a phone, and arranged in a perfect honeycomb structure — but they aren’t.

Cell towers are placed where they’re most practical and profitable. Urban areas have a high number of towers close together while towers in rural areas are spread further apart, and the further you are from a tower, the weaker the signal.

Population density is obviously the biggest factor, but there are also extra costs in placing a tower on difficult terrain and far from other infrastructure, and, of course, placing an unsightly cell tower in an area of outstanding natural beauty is often forbidden. People who want to get away from it all don’t want their view of the wilderness blighted, even by something as useful as a cell tower.

As a general rule, the further you are from other people (and therefore the more likely you are to need a phone) the worse your signal will be. Added to that, mountains, buildings, and even trees can block or dampen a signal.


So if you find yourself struggling to get a strong enough signal to make a call, what should you do?

1. Turn It Off and On Again

If the problem you’re having is a one-time thing and there’s no obvious cause, simply power-cycling your phone may fix it. (That’s my solution for everything!)

This allows your phone to look for another tower to connect to, and it may find one with a stronger signal. Switching in and out of Airplane Mode can do the same thing, but won’t fix any other problems with your phone that may be preventing you from making calls.

2. Charge Your Phone

If your battery is low, your phone is likely to go into some sort of power-saving mode, so it will be dedicating less power to transmitting your cell signal. Charge it or, if that’s not possible, turn off any power-saving features (but bear in mind that your battery will drain faster).

3. Move a Bit

The way you hold the phone could be a problem. If you’re covering the antenna, you’ll weaken the signal. Try changing your grip. It’s worth finding out where the antenna is on your phone to see if that’s the cause of the problem.

If you’re indoors, go outside. The walls and/or roof of a building can dampen cell signals. Going outside, or even just opening a window, may be enough to make it work.

Sometimes just walking a few feet in any direction can improve things. Reflected signals can interfere with themselves and lead to dead spots. Other electronic devices can also cause interference. If there’s no obvious cause of interference, just walk around and see if things improve. iPhone users can check their signal strength easily How to See How Strong Your iPhone's Signal Actually Is Did you know that your cell signal strength indicator may not be as accurate as you think it is?

4. Move a Lot

You may just be too far from a cell tower to get a usable signal. If you’re on the road, the best option may be to simply wait a few minutes and try again. But if you’re staying put somewhere and unable to get a signal, traveling towards a center of population or to higher ground might help.

Man Looking for Cellphone Signal

Even if you can see a cell tower, you may still find you have a weak signal. This is because cellular transmitters are often uni-directional. Start walking in a circle around the tower and you’ll eventually hit the right path of its transmission. (Of course, it’s worth remembering that not all towers serve all carriers so you may be wasting your time.)

In a situation where you have a poor phone signal, they may not be accessible to you — but if you’re planning to travel to a remote area, you can check in advance what you’ll need to do to get coverage.


5. Get a Better Phone

If you often find yourself with a poor signal, no matter where you are, your phone could be the problem. It could be faulty or just have a weak antenna. The latter won’t matter that much if you’re somewhere with a good signal, but where the signal is weak anyway, the quality of your antenna could make all the difference. If you constantly have problems in areas where your friends and family don’t, maybe it’s time to upgrade.

6. Get a Better Carrier

The problem may not be with your phone, but with your carrier. It may be that your carrier doesn’t have a very good network or just has patchy coverage where you live or work.

Again, check with friends and family. If people with the same carrier are having problems while people with a different carrier aren’t, then it’s probably time to switch. Even if you’re under contract, if you can argue that the service being provided is sub-standard, you may be able to get out of it without paying a termination fee.

7. Use Wi-Fi Calling

This obviously won’t apply in every situation, but if you have a Wi-Fi connection and a poor cellular signal, you may be able to use Wi-Fi calling instead. This is supported on both iPhone and Android phones and by most cellular carriers.

With Wi-Fi calling, in case of a weak signal, your phone automatically switches to Wi-Fi and you can still make and receive calls and text messages as normal. Check with your carrier if it’s something they support. It’s worth setting up in advance because you never know when it will be useful.

8. Add More Power

If you frequently have a poor signal at home, Wi-Fi calling isn’t an option, and you aren’t prepared to sell up and move closer to a cell tower, then you may want to invest in a signal repeater like a TDicallTM Signal Booster Mobile Repeater.

Similarly, if you often drive through areas where you have a poor signal, an antenna or booster for your car could improve things too.

In the U.S., FCC regulations require carrier approval for signal repeaters. In the U.K., it is legal to buy or sell them but not to use them! In other jurisdictions, check with your carrier whether you can use one, and what type you need.

If none of these options work for you, you may still be able to use your cellphone to communicate in other ways. An SMS message doesn’t need the same strength of signal as calls or internet, and even if it fails at first, your phone will keep trying to send it until it succeeds.

    Thank you for the information as a cell technician and a computer tech for a major corporation I understand the technology most people don't understand the behind-the-scenes and at the end of the day it really doesn't matter as long as you can use your phone that's all that people want... Anyways thanks for your time have a good day keep up the good work.

    Resetting network settings can help also.

    Believe it or not, I have more problems with Wi-Fi calling than I do using T-Mobile 4G! I live in a rural area, and I often get only one or two bars from the tower. But when I switch to Wi-Fi, others often complain they can't hear me or hear an echo. I have pretty good internet service (60 Mbps) and a pretty good router. But my phone is at fault, I believe. It's a ZTE knockoff of Samsung (Axon Pro) with loads of features--high quality audio, video and photo (supposedly). But I notice that nothing seems to work quite as my older Note 3. Ready to switch back.

    You should also try standing on your head while you try to make a call.
    It helps a lot. Trust me.

      Worth a try! Just make sure to turn your phone upside-down too.

    One more tip: it seems the hand you hold your phone in can make a difference. For most phones, you'll get a better signal holding it in your right hand, or better yet using it hands-free.

    I am sorry but to be honest this is the worst article I have come across in years. This is like an amateur teenager without any knowledge of the technology and writing it just for the sake of writing. U just wasted my 5 minutes precious time reading this. More a bit, move a lot, get a better carrier? Are you kidding me? Why is this article even allowed to be published.

      Really. I expected more technical tips, like "got to settings > something tech > disable Radio AGC" or something, not tired-tech-support "turn it off and on again" or "move a little"

      I agree with you. Complete waste of time - useless article.

    I don't want to accuse you of anything but this is clearly a article bait because really when you read it you see that in general these tips are not tips at all,
    Move , keep it charge, move more, or get an adapter.
    There i just resumed it

      Thanks for the feedback, David, but I think your summary does my article an injustice. Not everyone would think to charge their phone to get a better signal, or realize that the problem they're having could be hyper-local.

      Agreed with David. This is an April fool article. What a joke.
