The free phones They are compatible with any operator. Whether Vodafone, Movistar, Orange or MásMóvil, if your mobile phone is free you can change the SIM at any time and use it with your new line. Now, for there to be free mobiles there must be mobiles that are not.
What does it mean that a mobile phone is not free? Simply put, that is restricted to a single operator. This was very common until not so many years ago, when operators gave away phones or offered them much cheaper than their market price when making a portability or extending the rate. Currently it is rarer to see it, since it is more normal to buy phones in Amazon, Phone House or cash with operators. Knowing if your mobile is free or not very simple, so let's do it.
The easy and universal: using a SIM from another operator
The easiest way to know if your phone is free is removing your SIM and entering another operator's. This system works with all phones regardless of their brand for a simple reason: if you cannot access the mobile network, your mobile phone is not free. If you can enter the PIN and connect as you would with your SIM, then it is.
The problem is that it is not always possible to access a SIM from another operator. Some friend or relative may leave yours, but if it is not possible do not worry, there are other methods equally reliable.
Where you bought it?
As a general rule, any phone you buy at Amazon, Phone House, Carrefour, MediaMarkt or any large surface will be free. The same if you buy it in official stores, see a Mi Store or the Samsung website, you will not have problems either. In short, if there has not been an operator involved, with almost total security you will have a free mobile phone in your hands.
As a general rule, if you bought the phone on your own without the intervention of an operator, it will be free
If you bought it with operators and cash, most likely it is also free. In the case of Spain, the majority operators bet on selling free mobile phones at their normal price, only with the option of financing them with the rate in exchange for a permanence.
Even so, if you bought your phone from the operator, the simplest is that call the customer service phone and ask. If they tell you that the mobile is not free, you can ask for the release. It is free, but keep in mind that you may be charged a reduced amount for management fees.
Other alternative methods
The two methods mentioned above are the simplest, but not the only ones. You can try other systems that depend on the manufacturer and some codes That, everything is said, may not work on all devices. We leave you here those of Huawei, Samsung, LG and Sony:
- Huawei mobile: Open the phone app> dial * # * # 2846579 # * # *> in the menu, select Project Menu> Network Settings> SIM Card Lock sate query. If the text "SIM Card Lock state NW_LOCKED" appears, you have a free mobile.
- Samsung mobile: Open the phone app> dial * # 7465625 #. If "OFF" appears, it is free.
- LG mobile: go to Settings> About phone> Software information. If the "Software version" section ends in "EUR-XX", it is free.
- Sony mobile: open the phone app> dial * # * # 7378423 # * # *> Select "Service Info"> Go to "Settings"> Search for "Rooting Status" – If "YES" comes out it's free.
As you can see, there are several methods to follow, but The one that will work on all phones regardless of the brand is the first. If you can access the SIM of another operator you can check it in a second and then yes, call your operator and request the unlock code to proceed.
