In case you want to have different numbers for your private and business phone, but you don't want to have two phones with you all the time, you can use a dual sim version, and in the article below I present the steps you have to follow to configure how it serves you best.
If you bought a dual sim phone and do not want to go to the default settings, in which sim 1 is used for voice calls, text messages, data connections, etc., you can follow the steps below to configure which suits you best. Often mobile operators offer different price conditions for certain services (calling, messaging, data service) and you can choose different options depending on coverage or costs. It's not hard and the steps below are for Android phones.
Find the Android version
Initially you need to find which version you have installed on your phone to know exactly where to find the commands you need. Enter the settings and search for the phone box. You can also use the search bar. After entering the field about the phone look for Android version and you will find a number of type: 9, 8.0, 7.0 etc., which have certain correspondences with a specific name that you can easily find on the net, such as for example: Android 9 – Pie; Android 8 – Oreo; Android 7 – Nougat; Android 6 – Marshmallow; Android 5 – Lollipop; Android 4.4 – Kit Kat; Android 4.1 – Jelly Bean etc.
Access dual sim settings
In the next step you look for the settings on your Android phone, access the wireless field and networks and you will find a section called dual card settings (it can be positioned at the beginning or below, so I recommend you to search carefully). Once you find it, click on it to open the next field. Here you will see the two sim cards displayed, remember their names so you can easily identify them in the next steps, and you will see the operating status of each.
You will search for the next field of interest, namely your favorite sim card or the default sim card , in order to be able to see the settings on each sim. Here you have several options and they are structured according to the version of Android you have and the manufacturer, but all refer to voice calls (you can choose the default cards from which to make calls), text messages (see which card is best suited for sending messages), data service (set the active sim for internet connection) and bluetooth calling (if you are behind the wheel or you are very active and use a bluetooth headset for calls you can set the card on which you want to use it in this case). But let's take it step by step.
To choose the default sim card for voice calls you need to access that setting, which can be voice calls or the default calling card . Click on it and you will see a field with the two cards and another option to always be asked which card you want to use.
Depending on what you want, choose a suitable field, either choose a card for which you have a better offer given by the operator, or go for the third option and you will be asked each time which card you want to call ( always wondering or unsettled ). In the third case, when you want to make a call, a box will appear in which you will choose the sim card from which you want to make the call and choose the right card.
Here you have two options depending on what your phone offers, so you can choose different settings for which card to use for text messages and dialing, or the same default card for dialing and text messages. In case your phone allows you to set another card go to SMS messages and choose the most convenient sim in terms of costs offered by the operator. If not, you will have the same default card as for calling.
For a Dual SIM phone you can also choose the default setting for the data connection which can be that of the operator with the best 4G coverage or which offers you the best costs. Access the setting called network for the data service or default mobile data and click on it. A box with the two cards will open and you will choose the one that suits you best.
If you have different operators for the two sim cards, be interested in the 4G coverage map and the related costs or see the offer you included in the subscription to set the sim that offers you the best connection, either locally or in travel time at the lowest possible price.
More modern phones also offer the possibility to choose the default card from which you can make bluetooth calls. Thus, you will search for the setting called preferred bluetooth call settings and press it. A box with the two sims will open and you will be able to check the desired card.
You managed to follow all the steps and now you have the desired settings on each card, depending on your wishes. In case you are not satisfied with what settings you made initially, you can always make certain changes, in case the operator's offer changes and you receive better conditions for calls or data service on the other sim, or you are simply not satisfied with the choices you made.
Now on the market there is a great diversity of models of dual sim phones with Android and some settings may be different from what we presented above, but, after you find the version of Android you have, you can look more focused, in in case you can't find the presented settings or you have a more special model.
