WHATARE SIM CARDS AND UN-LOCKED PHONES?
You have probably heard the terms ‘SIM card’ and ‘unlocked phone’ on more than one occasion. In this age of modern technology, words such as these are fast becoming part of most peoples’ vernacular. However, if you aren’t quite sure what they mean, don’t worry; you’re not alone. You might be surprised at how many people simply nod along when someone uses a technological term he or she doesn’t understand. Well, you don’t have to fret. Read on and you will see what the deal is with those SIM cards and unlocked phones.
The SIM in SIM card stands for Subscriber Identity Model. The SIM card is the memory chip that goes into your cell phone, the one that you replace whenever you get a new phone. This makes upgrading your phone a breeze. This card holds many kinds of data, such as personal information, phone numbers, text messages, and more. SIM cards operate with the GSM network also known as the Global System for Mobile Communication.
An unlocked phone is also simple to understand. It simply means that the phone is able to accept a SIM card from any carrier, not just the one from whom you bought the phone. This opens up a world of possibilities for phone users. Most of the phones in the United States are locked, so when you get on a plan like the ones offered here at Roam4Less, you might need to order one of the phones available to ensure it is unlocked.
As you can see, the above terms are easy to understand and remember. The next time someone tells you that their new phone isn’t unlocked so they won’t be able to transfer their SIM, you will know what they are talking about instead of just nodding along!
