Mobile technologies have undergone rapid changes. Modern phones have several advanced features. Mobile phones can be broadly categorized as SIM-free, contract, and pay-as-you-go. Among these three mobile versions, SIM-free mobile phones are the most popular among customers. The mobile without SIM does not have a SIM card. This card is the network access card of the mobile service company. Without this card, the cell phone user cannot access the mobile company’s network services. The network card is unique by nature. You cannot access a service provider’s network using the access card of the different service company.
SIM free mobile phones are cheaper than the other versions of mobile phones ie contract and pay as you go. The advantages of SIM-free mobile phones are innumerable. The owner of this type of cell phone is free to use the network card of his choice. These categories of mobile phones are generally based on GSM technology. Modern GSM devices are packed with sophisticated technologies such as 3G compatibility, high-quality music players, longer battery backup, and much more. Therefore, the person will enjoy the high class features of these widgets.
There are several mobile service companies that offer deals on SIM-free phones. These offers usually include free offers in terms of airtime, internet download, text messages, etc. In the UK, free mobile phone deals are provided by service companies operating in the region such as T-mobile, O2, Virgin etc. Therefore, customers who buy these widgets can also get free offers from mobile service companies. Sometimes mobile companies also introduce their cardless devices in the market with fabulous freebies like computers, LCD TVs, iPhones etc. The other benefit of this type of mobile deal is that the person is not required to abide by the contract agreement of the network company. If at any time, the phone owner becomes dissatisfied with his existing service company, then he can replace his existing SIM card.
However, there are also some disadvantages of SIM Free mobile phones. People won’t get great free offers like you find with pay as you go and contract widgets. Low cost cardless cell phones do not carry advanced Internet and multimedia applications. Service plans from most GSM providers are not cheap compared to other network carriers. Barring these drawbacks, these phones are suitable for all classes of mobile customers.
