It usually happens on most occasions that once we enter the house we witness that our smartphone coverage drops considerably. This is due to several things, among them, for example, being between four walls, being surrounded by electrical devices that considerably affect this aspect.
Going from having four or five dashes to two or three greatly affects call performance, even losing voice on both outgoing and incoming calls. This is usually fixed by following a couple of tips, for this reason, everything needs to be improved if you want to obtain quality when receiving a call.
Throughout this tutorial we will explain how to improve mobile phone coverage at home, going from having the minimum to several and even all the stripes. Imagine being able to improve this, with this you will always get the maximum and enjoy both the call and the mobile data always at its best.
The loss of coverage, something normal

Throughout the use of the phone at home we will notice how the mobile coverage will vary, for this reason you always have to go from one side to another until you see the site and the best position. Going from one room to another and checking the lines, the difference is to see if it improves, gaining at least one connecting line.
Being between four walls, the loss of coverage becomes normal, although it is true on the other hand that we can improve it several points with some tips and tricks. Today we even have devices that will improve this and we will win in the end in health when talking on the mobile.
The living room is another of the places where we must test to see if it improves the network of our phone, which usually goes down depending on the area of the home. Mention that today there are quite a few people who purchase signal amplifiers, significantly improving the coverage of their device in areas where before it did not have the four or five bands.
Use a signal booster

One important thing to consider is to use an amplifier, it will come in handy if we seek greater coverage, thus improving in the different areas of the house. An amplifier has a small cost, that is why we must look for one capable of giving range to one or several telephones of all the meters that make up the house.
You have them at many prices, they range from 40 to 250 euros, the installation is not too complex and it is valid to expand the coverage, both of the phone in calls and that of 3G/4G/5G. This device is installable, some need an antenna to direct it towards the street and improve ours in the house.
Kafuty is one of the manufacturers that have decided to launch an amplifier For less than 43 euros, specifically 42,41 euros, you can have one and install it. It has its own charger and thanks to it we can have a range of more than 50 meters at home, which is quite a lot if we move from the bedroom to the living room and vice versa.
try to change room

After seeing that in that room it has not improved, as long as you don't install an amplifier, try changing rooms, going from one to another and see if it has improved. It highly depends on the bands, if you get at least one up, always try to use that same room for call use.
Try to use another room to yours, also you can always try in the living room as a suitable place to see if the mobile coverage improves. The spaces so closed mean that we do not get to enjoy the best connection, also try to be as close to the window when talking on the mobile, it is one of the things that always improve coverage.
Try to move through the different rooms, as well as in the living room, if you see that it is improving you can always use a specific point to talk, as well as for navigation if you do it by data. Wi-Fi is an option if you want to browse, make calls using VoIP applications, WhatsApp and other tools.
Check the SIM

Sometimes the problem lies with the SIM card, coverage usually improves sometimes if it is replaced, so check that it has not suffered over this time. Check that there is no dirt when it is used, dust is another element that damages it over time.
Check that the SIM card is not worn out either, if it is ask for a duplicate from the operator you are with, it usually has a fairly low cost. From 6 to 15 euros, it largely depends on what the operator wants to charge, sometimes they usually do it in the day, other times they take a little longer than expected.
There is no need to change the SIM, so a duplicate will take no time not too high a cost, otherwise it is clear that the important step is to replace the card if you see that it has a lot of use. Replacing the card will require you to take out the old one and put the new one in the SIM slot. Sometimes we have a double slot, use 1, it will be marked by a number.
Airplane mode, a solution

Although it seems that airplane mode is useless, this is not the case. Activate airplane mode once you see that you have little coverage and deactivate it after just a minute. The phone usually searches for an automatic network, it will always search for a good one, at least the one that works correctly at the moment.
If you change your location, the phone will search for a different network, it usually searches for the best, the closest and the one that is possibly worth it in every way. Mobile networks are often very important, a connection to a network that is less overloaded and close by will do much better.
