The Difference Between CDMA and GSM
After the cellular phone, the next thing on your shopping list is probably going be some cellular accessories, and it’s absolutely astonishing the stuff they’ve invented to go with a handset, many from the Didn’t Know You Needed It Department. But the one true must-have accessory of then all has simply been overlooked, because it’s from the Didn’t Even Know It Was An Accessory Department! Given that all too many wireless providers like locking their phones up so that they can’t work with SIM cards from another provider, it’s possible to reverse this programming with the help of Cell2Get so that your phone can work with any SIM card, from any carrier. And isn’t that just like an accessory, to help enhance your use of something?
More than carrying cases or belt clips, unlocking your GSM cell phone is very important to the use of your phone. After all, what is it that cellular accessories do, anyway? They go with your cell phone to somehow enhance your experience of the device. Unlocking your phone is not a physical accessory, but it definitely enhances your experience, making it not only possible but very convenient to switch carriers while keeping the same phone!
Don’t know what GMS and SIM mean? Well, many kinds of cellular technology exist, with different protocols and standards, and one of them is called GSM. It’s not as common here as another called CDMA, but most countries use GSM primarily, if not outright exclusively. Now all else being equal, it shouldn’t matter much in terms of such issues as call clarity and coverage. However, if you want to switch providers one day, it will make quite a difference, unless you don’t mind throwing away your handset (which you really should recycle instead!).
Now there is a unique electronic serial number for each and every phone, which is used by your carrier to identify your account. Through this identifying number, the carrier knows that a certain phone is yours and routes calls to you this way. But GSM cell phones are not directly linked to their owners, where the phone itself contains the serial number. Instead, each GSM handset contains a removable Subscriber Information Module card, or SIM card, that holds the ID number. This means that you can insert any SIM card into any GSM phone, and vice-versa, and everything works just like you’d expect it to. Thus, when switching carriers, you only insert the new SIM card from your new carrier into your existing phone, and that’s all, with no account set-up or registration on your part!
