Buy a mobile phone installment with an operator is still a convenient alternative for facilitate the purchase of a new smartphone without a large initial outlay and that sometimes can be a definitive price below that which can be accessed on the free market, especially if we take into account that the operators also offer discounts to deliver your used mobile.
If during Christmas it was Vodafone which took the opportunity to extend the discounts in Exchange for mobile used, now it is Movistar that puts the sales as an excuse to increase the discounts with one discount of between 29 and 100 euros the measurement of the delivered mobile.
Additional discounts will depend on the model of phone that you buy and sometimes also of the model that has to deliver, finding a additional discount of 100 euros to buy a LG G4 and deliver a LG G3. For the purchase of a Huawei G8 or a P8, also discounts only when you deliver as mobile used, but additional will be another model of Huawei.
The savers with less conditions since they will be valid regardless of the motive that is delivered are those associated with the purchase of a Microsoft Lumia 435, a Samsung Galaxy S6 edge or a Galaxy S6 edge +.
Discounts are valid if you are contract as if you are only interested in the mobile free but only apply on purchases in physical stores. In this way, Movistar discounts will save between 1 and 4 euros per month.
