Activation codes for free minutes are often used for pre-paid cell phones. These cell phones can only stay active as long as the owner purchases a certain amount of minutes that they can use. In order to obtain minutes for free, it is necessary to either steal a card or hack the codes, both of which are not recommended. Alternatively, cards can be purchased from sites like eBay and Amazon which
. will allow you to add minutes, and these are often not too expensive. Both of these sites allow you to purchase on cards that owners have but are not using, but on eBay sometimes an auction is used to determine who gets the card.This type of plan is ideal for those who do not make many phone calls and do not have a use for a standard cell phone contract. The pre-paid option allows them too still use the phone whenever and as often as they need, while only paying for needed minutes, as opposed to a flat, monthly rate. Children are also great candidates for this option for two reasons. First of all, children do not make calls as often as adults, so they have less use for a full contract. In addition, this option allows the parent to limit their kid to spending only a certain amount of time on the phone, which is great for those with very chatty kids.The two biggest carriers of pre-paid phones include T-Mobile, Virgin Mobile, Sprint and AT&T. In order to decide which carrier is best, make sure to consider the price of cards to add minutes, as well as the different places they can be purchased. The actual phone available to the customer should be another factor, as should the coverage provided in the area. For example, if T-Mobile does not get good service in the customer's location, then that customer should avoid T-Mobile and try Virgin Mobile, Sprint or AT&T.
