Why iPhone switches from LTE to 3G and what to do about it

The use of the Internet in iPhone is the most important function, without which the smartphone actually becomes useless. To save data, users can always choose which data technology to use – LTE, 3G or EDGE, known simply as “E”. But there is one problem: sometimes iPhone switches from LTE to 3G suddenly. Because of this, not only pages do not load, but also the download of iOS updates, applications and synchronization with iCloud is suspended. Why is this happening, can it be fixed and what to do if LTE on iPhone switches to 3G? Let’s try to figure it out.

Switching LTE to 3G on iPhone? We tell you what you need to know about it

Why is the internet switching from 4G to 3G

We noticed that sometimes even indoors iPhone switches LTE to 3G in a short amount of time, even though you haven’t even moved? The main reason for switching the cellular network between different standards is signal instability. It all depends not only on where you stand, but also on what surrounds you.

Let’s say in new buildings network on iPhone can switch even at the window, even in the elevator: what matters here is what the house is built from, how many base stations are around, as well as the presence of interference – for example, airports are nearby. And given that radio waves do not have a constant direction, the quality of the network can change even in one microdistrict. It turns out that the smartphone is simply looking for the best signal quality, which in turn often changes.

Constant switching between LTE and 3G is a real pain for any smartphone owner

If you are in a village, you may notice that iPhone runs on 4Gbut internet speed is slow. The fact is that there can only be one base station near you, so all the smartphones of everyone who is nearby can be connected to it. Accordingly, the signal is good, but the speed is not very good.

You may also notice that sometimes while talking on the phone, iPhone includes 3G. Why is that? The fact is that LTE has VoLTE mode (Voice Over LTE) is a voice communication technology, but not all operators support it yet, plus high-quality LTE reception is still not available everywhere. Add to this the fact that it should work for both subscribers, and such an ideal scenario is not always possible.

What to do if the Internet does not catch well on iPhone

If you’re tired of what LTE and 3G on iPhone keep switching and interfere with the normal use of the Internet, the best way to temporarily enable 3G in the settings. Most often, the network switches due to the fact that LTE is bad in a certain place – you can notice this by 1-2 divisions of the network indication on the screen.

Even the presence of two divisions of LTE does not mean that there will be no communication problems

Thanks to this, the Internet is highly likely to work without failures, but much slower. Keep in mind that with 3G enabled image quality in facetime will decrease, and when making a video call in Telegram, a 1-2-second delay may also appear during the conversation. Fortunately, it disappears if you turn off the camera and use the audio call.

The problem with switching communications from one standard to another is wider than you think, although it often lies precisely in the reception of the signal of one or another operator in a certain place: for example, if one connection in your area does not work well, then it can be solved by changing the provider.

At the same time, there are no guarantees that everything will work perfectly for him: signal reception in one place may improve, and in another it will become worse. Unfortunately, you can only determine this yourself: you can try to test the SIM card of another operator before changing the SIM card. But are there simpler methods to make the reception stable at least for a while?

  • If a smartphone switches between 3G and LTEbe sure to select 3G Only.
  • Turn off data saver in your cellular data settings.
  • Turn on the power saving mode: while it is running, the smartphone will not download data in applications in the background.
  • When using tethering mode, connect your iPhone to a PC: this way, the number of disconnections is noticeably reduced.

Despite the fact that each operator boasts of a large coverage area, not every suburban area has a good connection. My friends put themselves signal amplifiers: this simple device allows you to improve signal reception not only in the countryside, but even in the city on the lower floors of houses. Usually one device is enough for the house to have good LTE reception without switching to 3G.
