Why is My Cell Phone Data So Slow? 4 Causes & Solutions.

Have you ever wondered why your cell phone data is so slow even with 3-5 bars on your phone? There are many reasons for this which actually makes a case for D.P.T. and E.R.T. cell phone boosters. With Smartphones being the perfect and the quickest most reliable way of browsing the web and sharing and communicating via the internet, ensuring your internet speeds are the highest possible and most reliable is key.

However, this usually doesn't happen all the time whether at home, work or in your vehicle or boat. Here we discuss the reasons why your cell phone data speeds are low and how you can deal with this using a new and effective technology in D.P.T. and E.R.T. cellular amplifiers whether you're on your car, home, boat or office.

1. Carrier data throttling.

Is your carrier throttling your cellular data? Did you select a throttled data plan? Throttling the data means slowing down the wireless transfer speed of wireless data. Throttling isn't something new. Putting a limit on the browsing speeds is normal and happens in different ways. For instance, the data plan you may have selected from your prepaid carrier or MVNO might be throttled and indicated so. In most cases, it allows some carriers to offer cheaper data plans than their competitors.

While many carriers offer unlimited plans, the truth is that you can still browse at the speed you want and use the amount of cellular data you need but still remain under the threat of being throttled if you hit a specified threshold. Once you have gone over the specified limit, the carrier simply slows the speed until the monthly data plan cycle is over.

In recent times, major US carriers such as AT&T, Verizon and Sprint now tier their unlimited plans where the throttling threshold for high-speed data is way confusing due to larger data caps. For instance, Verizon's 22 GB "Beyond Unlimited" data plan with 4G LTE speeds is now throttled at 75 GB. Verizon slows down the browsing data speeds once you hit the 75GB ceiling.

With 22 GB unlimited data plans by AT&T, the data speed is slowed down if you hit the cap to a miserable 128 kilobyte per second. Sprint unlimited data plans on the other hand throttle data speeds if the user goes above 50GB per month with capped streaming, gaming and LTE speeds.

Essentially, it is safe to check with your carrier whether the cell phone data has slowed due to throttled data plans before you determine what else could be slowing your cellular data. To remove the cap on high speed data, you may have to shell out a few more bucks each month. A signal booster can help to some extent (atleast enable it to function at slow speed allowed by Carrier) instead of causing the browser to literally halt due to the compounding effect of weak cell signal. While high GB transfer allotment does not directly affect better or worse phone reception, ensure you have enough high maximum speed "GB allotment" to prevent getting throttled before the end of your billing cycle.

2. Have you lately cleared your cache?

In case you have ascertained that the slow data problem still persists, it might be a good idea to check the phone's cache. One of the reasons why you browse fast is due to the cache's ability to save lots of data related to websites you have visited - such as While browsing becomes less of a hustle, with time your phone data does slow quite a lot due to accumulation of all the cached pages, website cookies, etc. While high GB storage phone with lots of available hard drive storage space has no impact on reception, the lack of Random Access Memory (RAM) is akin to taking away air or oxygen which results in choking. Phones need RAM to perform tasks so may even freeze if it runs out of R.A.M., leave alone provide good data transfer speed or reception.

Make the most of cache cleaners on your iPhone or Android phone app stores or preferably clear the cache manually on your Smartphone each day or atleast once a week. You may even restart your phone for quick clearing of RAM (Random Access Memory). Worst case scenario, backup phone data and reset the phone to factory settings which will pretty much guarantee you will get back to the data speed you had when your phone was brand new.

3. Wrong network connectivity.

3a. Playing Ping-Pong Between Cellular and Wi-Fi.

In a perfect world, smartphones should "ping-pong" seamlessly back and forth between the wifi and cellular signals depending on which one is strong and consistent. Unfortunately, that is not the case with most smartphones. Once they have a strong wi-fi connection, they tend to stick with it even though it gets too weak despite the fact that a stronger cellular connection is available. Turn off wi-fi option in your settings to force the phone to use cellular with a strong consistent connection, if available.

3b. Forcing Phone to use faster network 3G -> 4G -> LTE -> 5G.

Did you know that you could force your phone to use a certain network that is faster? If you're at a spot where 3G signal is stronger, you will be stuck with slower speeds. Simply turn on and off your, "Airplane mode" if you have moved some distance. It should reconnect to another faster network like for example 4G, if 4G signals are strong enough at the new spot where you're using your phone. If you have been using the wrong or unavailable connectivity on your phone, chances are that your cell phone data is very slow. If you don't get to make the most of the right network you will definitely browse with low speeds or fail to connect to the web at all due to weak or zero connection.

To be on the safe side, go to your Smartphone’s settings in mobile data and select network mode. You can then choose the best network possible for your phone from 5G, 4G LTE, 3G to 2G, depending on your phone. You can also select auto option, which gives your phone the option of switching into the best and reliably available network automatically within your locality. Once you do this, do try out your cell phone data to see if the problem has been rectified.

4. Type & condition of phone.

Is the type of phone you’re using affecting your browsing speeds? It is possible that your cell phone signal is superb right off the carrier, cell phone data reception top notch, and the network you’re on just fabulous, fast and reliable. However, due to your phone being slow and unable to connect to the internet fast and normally you might be exposed to unreliable and stumpy data speeds.

It might be due to lots of apps on your device or the hardware of the Smartphone might be outdated or inferior, such as cheap Android devices and older Smartphones. Even so, the type of applications on your phone, cheap or high-end can actually affect your browsing speed.

All your bandwidth can be used up fast by lots of background app activities like downloads and syncing that slows the internet speed. If this be the case, Android download manager apps can help.

Outdated or mediocre apps can also slow your phone. As such, update your apps occasionally and delete apps you don’t need and manage their background activities. Also, it is perhaps time to get a new high-end and efficient Smartphone.

5. Radio frequency interferences.

According to FCC, cell phone reception, radio and television coverage are affected by interference caused by radio frequencies. As a result, cell phone data ends up really slow. As coverage is interfered with, cell signal lost temporarily or the voice/sound/ image quality the TV, phone or radio produces is affected. In most cases, this interference is caused by electrical equipment and transmitters.

Interference is ascertained with ease whether the culprit is electric equipment or transmitter by easily unplugging any of the different electronic equipment and components in the house. Simple tests can then be done to see if the problem is dealt with. In the process, you can actually isolate the source of the electrical interference affecting your cell phone signal.

While cellular phones make use of radio frequencies, interference protection is usually not available. Garage entry openers, doorbell transformers, electrical drills, hair dryers or even equipment such as sewing machines can also release interferences in short bursts. Fluorescent lighting or aquarium heaters have also been mentioned by FCC as causing patterns of cellular signal interference.

With such intrusion, the signal strength will be lost or weaken making it really hard to make calls, use cellular data and send texts and much more. While you can't do much about all the wireless activities going on around you, a cell phone signal booster can help deal with this problem by taking up the weak cell signal, boosting it up to 32x times before spreading it all over the vehicle or building. In the process, browsing the internet with your cellphone won't be any problem.

  • Do cell phone carriers still throttle data? I’ve heard different things about this bad practice, but it wouldn’t surprise me if they still do it. Clearing out your cache sounds like a good idea too. I didn’t know the TV and radio can interfere with your cell phone. Wow. There really are a lot of things that can weaken your signal.

  • my data is so slow and I feel bad because it’s terrible

  • I’m so surprised by how slow data is these days. I realize that some companies do it on purpose, so you pay for upgraded purposes. Why can companies get away with this? It’s a crime.

  • Pretty sweet discovery. I never heard of “forcing phone to use faster network.” I’m pretty sure my phone’s problems are due to my environment, but this is worth looking into. If it helps even a bit, it could be the difference between getting a booster and keeping things as they are.

  • I’ve noticed some problems with my Motorola. It does a good job with watching YouTube videos and accessing sites, but the voice quality is either good or bad. Looking at the price for a booster, I’m thinking I might drop a few books when my stimulus check comes in. For $259 it’s worth my trouble as I don’t use a landline.

  • “Why is My Cell Phone Data So Slow?” Sounds like a great rom-com movie for today’s generation or a new take on “Dude, Where’s My Car?” I’ve enjoyed using a cell phone since the late 90s, but somehow, the technology started getting erratic right around the time of smartphones. Anyone know why this is?

    Monty Samuelson on
  • I remember the first time somebody told me about clearing out the cache on my computer. It was such a big difference and I do it routinely. While I was unaware of clearing out the cache on my cell phone, it makes sense because a cell phone is a mini-computer (sometimes I still have trouble grasping this concept).

    Laura Watson on
  • In a case like this, I’d check the phone manufacturer’s website support section. The only other place I know is to click settings and choose the “update” option which will tell you if the next upgrade requires a new software version. Good luck!

    Peggy Garth on
  • I have an older phone and saw #4 (type and condition of phone). Is there any resource for checking to see if your phone is just too old to get the job done anymore? I’d like to know because I don’t know when I’m going to have money to get a decent upgrade.
